A sensor is a battery-operated small computer with an antenna and a sensing board that can sense magnetism, sound, heat, etc. Sensors in a network can use their antennas to communi...
This paper presents a sentry-based approach to power management in wireless sensor networks for applications such as intruder detection and tracking. To minimize average power cons...
In this report, we will provide the detailed theoretical analysis including some omitted proofs in our latest submission to Infocom 2008. For more details about the framework prot...
Abstract— Energy efficiency is a fundamental issue for outdoor sensor network systems. This paper presents the design and implementation of multi-dimensional power management st...
