Abstract

The effect of medium access control (MAC) for information retrieval on signal field reconstruction in large-scale sensor networks with finite density is analyzed. Two MAC schemes are compared: the deterministic scheduling and random access. For fixed sensor density, we show that there is a critical threshold of e/sup -/spl lambda/(1+o(1))/, where /spl lambda/ is the throughput of the random access protocol, on the sensor outage probability P/sub out/ beyond which the reconstruction performance of deterministic central scheduling is inferior to that of distributed random access.
