We present a simple, local protocol, {\protocol}, which
provides partial (but high) coverage in sensor networks. Through
{\protocol}, we demonstrate that it is feasible to maintain a high
coverage ($\sim$90\%) while significantly increasing coverage duration
when compared with protocols that provide full coverage. In particular,
we show that we are able to maintain 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, i.e., the desired level of coverage is maintained (almost)
until the point where all sensors deplete their batteries.
