Wireless TDMA mesh networks are multi-hop wireless networks which give various nodes access to the wireless medium based on a time-division schedule. Such networks have the potential to provide QoS for triple-play over a large coverage area. It is hard to give equivalent QoS with Wi-Fi based networks which are fraught with various hidden terminal problems.

At IIT Delhi, we have built a rapidly deployable wireless TDMA network with similarities to the WiMAX-relay standard. Our network will be useful in disaster management and military battelefield scenarios which cannot depend on any prior existing network for communication. We have chosen a software-defined radio, called wireless open access research platform (WARP), to build our backbone mesh network.

In my talk, I will explain our network design, provide experimental results, and describe applications we are building for disaster management. I will also highlight our experiments with commercial wireless TDMA mesh equipment which we leverage as a second-tier in our own mesh network.
