Title: Cell-Phone Based Micro-Location Tracking and Hands-Free Audio Alerting
Author: J. Morrison,Mobile Traffic Network,   Las Vegas, NV USA

Abstract: Services that can track the location of a user via a cell-phone are starting to emerge now that more and more cell phones have GPS chipsets built-in.  However, a network-based solution that could track users indoors (where GPS-based solutions often fail) could have even more applications.  This demonstration shows such a system and provides a peek into the types of services that could be enabled.

Title: A Framework for Mobile Applications based on a structured P2P Overlay
Authors: Mario Kolberg, Evan Magill, Martin Blunn, University of Stirling, UK; Michael Wilson, Peter Burtwistle, Sysnet, UK

Abstract: P2P applications are increasingly popular. Unlike traditional client-server applications they do not require central server resources. This makes them less costly to host and maintain. While there have been a large number of P2P applications been developed for PC based systems, there are only very few for mobile appliances, such as mobile phones or networked PDAs, and even fewer which operate successfully on the public mobile data network (GPRS, 3G), rather than WiFi. This is largely due to the difficulties posed by the restrictive data access to mobile devices (NATs, Firewalls by the network operators) and traditionally high charges for data communications. Recently, the latter point has been virtually removed by the introduction of flat-rate data packages by the operators. This paper (and demo) present a framework and applications based on a structured P2P overlay network which can successfully operate on the public data network.

The current implementation comprises of several types of data acquisition, archival, processing and visualization semantic services. These services interface with the heterogeneous target sensor platforms and use their ontologies to correctly interpret the data they provide and use the services they offer.

Title: Applying the ZigBeeT and Wireless Sensors to Monitor the Efficiency of Workflow
Author: Vincent Tam,   University of Hong Kong, Hong Kong

Abstract: This project focuses on applying the wireless ad-hoc network and sensor technology to monitor the efficiency of workflow. The project aimed at building a working prototype to demonstrate how these technologies can be combined to facilitate the analysis of the workflow efficiency, with the real-time data being captured through numerous low-cost and customizable sensors installed in different corners of a manufacturing plant. Besides, through any WiFi-enabled consumer electronic devices such as a smart-phone or pocket PC, a manager/supervisor can easily access such real-time analysis about a particular machine, a specific pipeline or section of machines anywhere, inside or outside of the plant, through the nearest WLAN access points provided. A wireless sensor implemented with realistic networks configurations will be presented. This research has produced results delineating the performance and limitations as well as the future development.

Title: Demonstration of Call-to-Web Session Linkage System
Authors: Masashi Toyama, Koji Murakami, Yoshiko Sueda, Osamu Mizuno,  
Nippon Telegraph and Telephone Corporation, Japan

Abstract: We demonstrate a prototype of a call-to-Web session linkage system for sharing a Web application between caller and receiver. The system makes a session linkage between Web browsers based on call session information of SIP, which is an application-layer control protocol mainly used for IP telephony systems. After that, the system offers Web servers information for the linkage so that Web servers can provide a shared Web service easily. This system can even be uses by a browser of home appliances, which are difficult to upgrade because those linkage protocols consist of basic browser functions.

Title: Demonstration of First Response Communication Sandbox
Authors: Dirk Bradler, Max Mühlhäuser,   TU Darmstadt, Germany
Jussi Kangasharju,  
University of Helsinki, Finland

Abstract: First response communication is tackled by several independent research groups. While there are existing prototypes and simulated results, comparison of first response solutions is hardly possible so far. We have built an universal XML based description format to handle all relevant settings and actions typical for first response scenarios. In addition we implemented a user-friendly movement and environment simulator which interacts with the network simulation on top of the simulated movement. The chosen data structure have proven to be well suited for describing settings and actions found in a first response scenario. The simulator combines movement and network simulation and therefore enables both, fine grained movement models and location aware network models with reciprocal interdependencies. The simulation results of the chosen communication approach are therefore finer grained than using a network or movement simulator separately. In this demo we show different movement and network models, perform movement simulations and show the interface for using mobility simulation within network simulators.

Title: Demonstration of Home Appliance Control Using Heterogeneous Sensor Networks
Authors: Takahiro Ito, Yuichiro Kato, Masatoshi Ogura, Hideki Kamiya, Hiroshi Mineno, Tadanori Mizuno,  
Shizuoka University, Japan; Norihiro Ishikawa, NTT, Japan

Abstract: This demonstration presents the system showed in the paper accepted at CCNC 2009 "Home Appliance Control Using heterogeneous Sensor Networks". By using this system, control of a network camera based on the value of a sensor is possible. With mobile devices, a user can set or delete the service, which would be executed when a predefined event occurred. When the value of sensors satisfies the event occurrence condition, this architecture detects it, and executes the service which is determined in advance. The definition of the event, which is composed of several types of sensors, is also possible. Therefore, a user can use sensors without being conscious of the difference of vendors. We demonstrate how to define an event and set a service against the defined event.

Title: Demonstration of Non-cluster Based Topology Control Method for Wireless Sensor Networks
Authors: Wenzhu Zhang, Lin Zhang, Jian Yuan, Xiaoxiao Yu, Xiuming Shan,
Tsinghua University, China

Abstract: Environmental surveillance applications usually require a long living cycle of sensor nodes, especially when they are powered by non-charged batteries. Inspired by cellular automata, we propose a non-cluster based topology control method to prolong the lifetime of wireless sensor networks. Differing from the traditional cluster-based methods, our approaches lead a special way to maintain longer system lifetime by sacrificing a small proportion of network coverage and connectivity degrees. The demonstration contains both theoretical simulation and system-level experiment, which will be instructive for future study.

Title:   Demonstration of Spam and Security Mechanism in SIP-based VoIP Services
Authors:   Jaesic Choi, Kangseok Chae, Jaeduck Choi and Souhwan Jung, Soongsil University, Korea

Abstract:   This demonstration presents spam scenarios and a lightweight security mechanism for protecting spam calls in SIP-based VoIP services. Generally, VoIP providers have been applying only the HTTP digest scheme to authenticate a UA. They may be not consider protecting SIP signaling between the light-weight UA and the SIP proxy using the TLS mechanism since it suffers from the heavy overhead for computation on the resource-constrained UA. Therefore, the spammer can send SIP messages such as INVITE or 200 OK directly to the UA or the SIP proxy, and then communicate with the user by establishing a media channel. This paper demonstrates several spam scenarios when the TLS mechanism is not established at the light-weight SIP UA. Besides, we will show that these spam calls can be protected by using our proposed security scheme instead of TLS mechanism.

Title: Demonstration of Standard IPTV Content Delivery Network Architecture Interfaces
Authors: Mohamed Fouz Menai, Frederic Fieau, Orange Labs - France Telecom Group, France; Achraf Souk (Université des Sciences et Technologies
de Lille, France; Sebastian Jaworski, Telecom Bretagne, France

Abstract: This document we suggest a demonstration of standard SIP/RTSP based Content Delivery Networks (CDN). The intended use of SIP based CDNs is in the scope of IMS based IPTV architectures that are being standardized in the Open IPTV Forum [1], ESTI-TISPAN and the ITU-T. The system includes a central server (Content Delivery Network Controller) analyzing all received content delivery requests. The Content Delivery Network Controller chooses the cluster of servers a request should be redirected to. The choice is made depending on client location, content availability, location and servers' global load. Each cluster is controlled by a Cluster Controller that would make the choice of the final VoD server to deliver the content, based on a fine grained analysis of the load of the VoD servers it manages. The system proves the feasibility of the standards and highlights the flexibility of SIP [1] interfaces when coupled with RTSP [2] to organize redirections within a CDN.

Title: DT-Talkie: Interactive Voice Messaging for Heterogeneous Groups in Delay Tolerant Networks
Md. Tarikul Islam, Helsinki University of Technology, Finland

AbstractPush-to-talk, a walkie-talkie kind of communications, has been gaining attention as a service in cellular networks. Unlike traditional walkie-talkies, however, push-to-talk requires network infrastructure for its operation. While infrastructure-less operation in mobile ad-hoc networks has been explored in the past, such approaches attempt to establish an end-to-end path for communications, which may be unstable and exhibit bad performance over multiple hops; and often the node density may be insufficient to establish such paths in the first place. In this demo, we apply the concept of asynchronous message passing using delay-tolerant networking to audio messages which get recorded and then transmitted via store-carry-and-forward from the source to the destination. This decouples audio quality from some extent from the instant dynamics of the network and enables intelligible communications at the expense of some potential extra delay. We present an implementation of the DT-Talkie on the Nokia N810 Internet tablets, leveraging the DTN reference implementation developed in the concept of the DTN Research Group.

Title: GridMedia+: A P2P Streaming System for Live and On-Demand Video

Title: In-network Real-time Adaptation of Scalable Video Content on a WiFi Router
Authors: Ingo Kofler, Robert Kuschnig, Hermann Hellwagner,
Klagenfurt University, Austria

Abstract: One of the most active research topics in the field of video signal processing is scalable video coding (SVC). The recently published extension of the H.264/AVC video coding standard introduces scalability features by employing a layered encoding of the video stream. In our work we investigated the usage of this scalable extension of H.264/AVC for in-network multimedia adaptation. We developed an RTSP/RTP-based proxy which exploits the layered encoding of the video and can perform real-time video adaptation on an inexpensive off-the-shelf WiFi router. This is achieved by applying a stateful, packet-based adaptation approach that keeps the computational costs at a minimum. With that approach it is possible to simultaneously adapt multiple video streams to varying network conditions or to the capabilities of the consumers' end-devices. In our demonstration we show the streaming of two scalable video streams from a server to a client and the in-network adaptation of the video at the WiFi router. The adaptation can be controlled interactively in the temporal, spatial and SNR domains.

Title: Media Delivery to Remote Renderers Controlled by the Mobile Phone
Authors: Andreas Fasbender, Martin Gerdes, Takeshi Matsumura, Ericsson, Germany; Andreas Häber, Frank Reichert,   University of Agder, Norway

Abstract: Nowadays, in most content delivery solutions the servcice is typically delivered to the same device that controls the session - thus, service delivery and control are tightly coupled. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the media player device and the targetremote environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials is performed. This paper describes a demonstration scenario and our prototype implementation.

Title: Mobile P2P Fast Similarity Search
Authors: Thomas Bocek, Fabio Hecht, David Hausheer, Burkhard Stiller,  
University of Zurich, Switzerland; Ela Hunt, University of Strathclyde, UK

Abstract: In informal data sharing environments, misspellings cause problems for data indexing and retrieval. This is even more pronounced in mobile environments, in which devices with limited input devices are used. In a mobile environment, similarity search algorithms for finding misspelled data need to account for limited CPU and bandwidth. This demo shows P2P fast similarity search (P2PFastSS) running on mobile phones and laptops that is tailored to uncertain data entry and uses available resources efficiently. In this demo, users publish and search for textual content containing misspellings without relying on query logging, as done by Google, and with a minimum distributed indexing infrastructure. Similarity search is supported by using the concept of deletion neighborhood to evaluate the edit distance metric of string similarity.

Title: Mobile Touch: NFC-like Interaction with Yesterday's Phones
Authors: Victor Klos, M. Oskar van Deventer, Mark van Staalduinen, TNO, Netherlands

Abstract: Near Field Communication (NFC) enables fast interactive mobile services as it allows two mobile devices to quickly and securely exchange information when they are within touching range. However, NFC-enabled phones are virtually absent on the market today, which impedes the break-through of these useful services. This paper presents the Mobile Touch Technology, which utilizes the mobile phone's microphone plus its connectivity capabilities to effectively emulate NFC with mobile phones that are already widely available on the market.

Abstract: In this demonstration we present an ubiquitous health monitoring system based on the NGN/IMS (Next Generation Network/IP Multimedia Subsystem). It enables us to be taken care of by medical professionals anytime, anywhere using portable medical sensors and mobile networks. To provide seamless health monitoring services, an open, secure and functional platform is required. Such a platform should support multiple functions such as real-time transfer, event notification, and continuous data accumulation. The NGN/IMS is a potential platform to fulfill these requirements, because it is a standard-based open platform, which provides AAA (Authentication, Authorization and Accounting), QoS (Quality of Service) support, event notification and a data management server. We present a system design and a prototype implementation on a NGN/IMS testbed.

Title:   Prototype Demonstration: Trojan Detection and Defense System
Ting Liu, Xi'an Jiaotong University, PRC, P.R. China

Abstract:    This paper presents a novel Trojan detection and defense system. The prototype searches the important files which contain users' confidential information on disk. All processes that access those files will be monitored by capturing and analyzing the IRPs (I/O Request Packets). The prototype can distinguish Trojans processes from regular ones by evaluating their API-calls with several machine-learning models, rather than traditional signature-based mechanism. Trojan's IRPs and processes will be suspended and killed to protect users' confidential information from attackers. Testing results indicate that this prototype can detect and defend unknown Trojans quickly and accurately.

Title: Remote Management of Non-TR-069 UPnP End-User Devices in a Private Network
Authors: Ben Hillen, Igor Passchier, Bas van Schoonhoven, Frank den Hartog,   TNO, Netherlands

Abstract: End-to-end broadband service delivery requires remote management of devices in the home network, beyond the home gateway (HG). The service provider can only put limited requirements to these of-the-shelf devices, and therefore has to make intelligent use of their given control and management protocols. We developed a demonstrator for the remote management of Universal Plug and Play (UPnP) devices in the home with a simple TR-069/UPnP proxy on the HG. It shows how UPnP devices can be discovered, configured, controlled and monitored with a legacy TR-069 auto-configuration server.

Title: Using SNS as Access Control Mechanism for DLNA Content Sharing System
Authors: Taeyoung Song, Yoshihiro Kawahara, Tohru Asami,
University of Tokyo, Japan

Abstract: The home networking becomes more interesting if users can share high quality contents with friends and colleagues living away from the user. DLNA certified devices allow users to share or access digital media contents on the same home network. However, the sharing of the content is only limited inside local area networks. In this paper, we propose a global content sharing home gateway named DAS (DLNA Agent for SNS). Different from exiting approaches using VPN, DAS enables to share specified contents to selected users with support of access control functionality provided by Social Network web services. As DAS behaves as a DLNA certified server, there is no need to modify commercial DLNA CE devices.

Title: Vanets: Case Study of a Peer-to-peer Video Conferencing System
Authors: Tareq Hossain, Yi Cui, Yuan Xue,
Vanderbilt University, USA

Abstract: We present a peer-to-peer video conferencing system, Vanets. Our system takes advantage of transcoding to optimize the video streaming rate of the participating peers. We use the active peer participant focus technique to allocate higher bandwidth to the user currently talking. Each participant maintains a local tree topology where the participant is the root and uses this topology to stream video. Therefore, passive participants receive higher quality video from an active participant, while receiving lower quality video from the rest of the participants.
