Abstract

In our demonstration, we will show how sChat enables mobile users to chat in groups via a WSN. We will setup a WSN consisting of 40 Tmote Sky motes in a 8x5 grid layout. All motes will run TinyOS and Agilla. We use a laptop as the registry to keep track of the groups in the network. We provide portable wireless devices like Sumsung´s Origami Ultra-Mobile PC with telosb motes attached to them so that they can interface with the WSN. Visitors can use these portable devices to group chat over a WSN. Currently, sChat only supports text messaging due to bandwidth constraints. In the future, our service may be easily extended to support audio and video communication.
