An energy-efficient fault-tolerant monitoring system for sensor networks

Published: 01 January 2008 Publication History

Abstract

Because sensors are often deployed in harsh and/or adversarial environments, the sensors or the communication links may fail and hence endanger the mission of the sensor network. Although using more redundant sensors can tolerate some sensor failures, in most cases, only limited sensors are awake to extend the network life time. Therefore, sensor status (such as liveness, density estimation, residue energy, etc.) has to be closely monitored and made known to the sink, which can promptly react to the sensor status changes.
