This work considers a multi-hop sensor network which is comprised of a large number of sensor nodes communicating with RF links. The authors assume that sensor nodes are deployed in an ad-hoc fashion to cover a specified area with their sensing capabilities. Sensors monitor, sense and collect data from a target domain, process it and transmit the information back to the specific sites (e.g., headquarters, disaster control centers). There are many potential applications of sensor networks including military, environmental and health related areas. Although the sensor nodes communicate using wireless links, there are fundamental differences between a sensor network and other wireless ad-hoc networks.
