Wireless Sensor Networks

Wireless sensor networks (WSNs), comprising of tiny, radio-enabled, multi-function sensor nodes, are becoming ubiquitous, thanks to rapidly decreasing hardware costs and advances in miniaturization technology. They open up opportunities to monitor the physical world around us at an unprecedented detail, and have applications in a wide range of domains starting from military applications such as battlefield surveillance to scientific applications such as habitat monitoring. Wireless sensor nodes are typically battery-powered, and in most cases it is not feasible to change the batteries post-deployment, making judicious use of the battery power of paramount importance. Our research in this area spans several problems related to energy efficiency in wireless sensor networks, including target monitoring, model-driven data acquisition, in-network query processing, and lossless and lossy data compression.
