pCover: Partial Coverage for Long-Lived Surveillance Sensor Networks

Abstract

We present a protocol for partial (but high) coverage in sensor networks. We demonstrate that it is feasible to maintain a high coverage (>90%) while significantly increasing coverage duration when compared with protocols that provide full coverage. In particular, we show that our protocol maintains 94% coverage for a duration that is 2.3-7 times the duration for which existing protocols maintain full coverage. Through simulations, we show that our protocol provides load balancing and that the desired level of coverage is maintained (almost) until the point where all sensors deplete their batteries.
