A combinatorics-based wakeup scheme for target tracking in wireless sensor networks

Abstract

Sensor networks deployed for the purpose of target tracking and intrusion detection have very specific requirements in terms of sensing coverage, timeliness of data and network lifetime. Many existing work focus on wakeup schemes that only attempt to prolong network usage but failed to address issues such as coverage, timeliness of data delivery, target tracking continuity and deployment cost all at the same time. Given any maximum target speed, our solution based on a Combinatorics approach, guarantees delay bounds and node lifetime bounds, critical for any practical deployment of a target tracking application. We support our solution further with simulation results. ©2007 IEEE.
