Context Aware Design of Wireless Sensor Networks

Ashfaq A. Khokhar

Due to advances in computer/network technologies and emerging ability to embed sensors in VLSI, existing computation and information paradigms have begun to acquire new dimensions.

Deployment of a vast array of tiny smart sensors (sensor devices with processors) interconnected over wireless channels are enabling their pervasive use in a variety of defense and commercial applications, such as environmental monitoring (e.g. traffic, habitat, security), industrial sensing and diagnostics (e.g. factory, appliances), infrastructures (e.g. power grid, water distributions, waste disposal), and battlefield awareness (e.g. multi-target tracking). While the task of developing and implementing pervasive applications for such a scenario is exciting, it poses tremendous challenges. In this talk we will discuss research issues related to context aware design and management of heterogeneous wireless sensor networks, and present results on the design of power efficient routing and MAC protocols for such networks.
