Research Agenda
Wireless mesh networking based on WiFi technology is an exciting technology that has huge potentials for the future of network connectivity. It has the ability to greatly increase the coverage of the current hotspots with significantly lesser deployment cost. To fully exploit the utility of this technology, a multi-radio setup is needed with appropriate channel configuration and route planning components. We introduced a self-configurable channel assignment protocol that able to provide substantially higher network capacity than current hotspots configurations. Such a multihop network is able to support real-time applications such as VoIP and video streaming through clever interference control and route planning.
Another exciting ongoing research agenda is the design of appropriate middleware and network stack for the future of sensing technology, namely wireless sensor networks. These networks afford unimaginable utility in diverse areas of applications such as environment monitoring, security surveillance, structural monitoring, target tracking and health monitoring. We have introduced different network protocols to enable scalable network operations using swarm-intelligence techniques. We have also introduced different in-network processing capability for sensors to perform distributed event processing for intelligent network self-operation in face of interesting event detections. We are able to apply this these components in diverse customisable applications. Numerous funding have been obtained for these activities both from federal funding through ARC and its affiliates, industry partners such as Sun Research as well as the university itself.
