To model and control such complex organizational systems, the use of scientific methodologies, such as participatory simulation and agent-based modeling, is becoming increasingly common. Further, users of these collaborative systems demand the availability of sophisticated tools that are able to present visually the results of cooperative simulation activities on the screen of handheld devices. We have designed and developed a software architecture able to support the execution of agent-based participatory simulation activities, and to render them in a 3D virtual world over wireless devices. We report on several experiments, gathered in the field, showing that the architecture we have developed is able to render, in a timely fashion, on a wireless device, the results of cooperative simulation activities performed by agent-based programming platforms.","PeriodicalId":316094,"journal":{"name":"First IEEE Consumer Communications and Networking Conference, 2004.

Due in part to the decreasing price of gas plasma, and other display technologies, digital signage networks are now rapidly growing in popularity and prevalence. Augmenting digital signage with wireless LAN technology enhances the narrowcasting model by enabling consumers to interact with the narrowcaster to obtain additional information from particular narrowcasters, e.g., advertisers, of interest. When explicitly permitted by the consumer, this enables the narrowcaster to obtain more information about the consumer. We describe the cost reduction and increased effectiveness of advertising that is displayed and managed using digital signage networks as opposed to traditional signage. We present an enhanced narrowcasting model created by augmenting the network with wireless LAN technology. We describe several scenarios where a system based on the model enables novel interaction between the narrowcaster and consumer. These features provide new support for mobile commerce. We then propose an architecture that implements the enhanced narrowcasting model that we have implemented in our system prototype.","PeriodicalId":316094,"journal":{"name":"First IEEE Consumer Communications and Networking Conference, 2004.

The role of clusterhead is a temporary one, which changes dynamically as the topology or other factors affecting it change. Finding the minimal set of CHs is an NP-complete problem. We study the performance tradeoffs between two clustering approaches. The first one is a simple clustering strategy, called virtual grid architecture (VGA), which is based on a fixed rectilinear virtual topology, while the second one is an optimal clustering strategy. We consider homogeneous as well as heterogeneous networks. First, for homogeneous MANETs with a large number of users and under the VGA clustering approach, we derive expressions for the number of CHs, worst case path length, and average case path length. We also derive expressions for the communication overhead. Second, we develop an integer linear program (ILP) that finds the optimal number of connected CHs in small to medium sized heterogeneous MANETs. Analytical and simulation results show that our proposed clustering algorithm (VGA), although being simple, is close to optimal.","PeriodicalId":316094,"journal":{"name":"First IEEE Consumer Communications and Networking Conference, 2004.

We describe a wireless video delivery system, WiVision, which uses IEEE 802.11 wireless LANs as the last mile for both real-time video distribution and on-demand video playback. WiVision can air both live events, such as on-campus seminars and sports activities, and prestored video streams, such as course lectures and financial analysis sessions, to mobile users, who can tune in to selected channels of their choice from their laptops or PDAs. An innovative feature of WiVision is the support for random video access based on keyword-search, where keywords are extracted from the closed-caption text embedded in TV programs. In addition, WiVision is able to broadcast video streams on the wireless link while seamlessly working with commercially available media players. The paper presents the implementation details of the real-time acquisition and network transport components of a fully operational WiVision prototype, and the results of a performance evaluation study on that prototype.","PeriodicalId":316094,"journal":{"name":"First IEEE Consumer Communications and Networking Conference, 2004.
