MobiCom Poster Abstract: An Energy-Efficient Fault-Tolerant Monitoring System for Sensor Networks
Oct 2007
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...
