BurstMAC - An Efficient MAC Protocol for Correlated Traffic Bursts

Free registration required

Executive Summary

Many sensor network applications feature correlated traffic bursts: after a period of idle time with almost no network traffic, many nodes have to transmit large amounts of data simultaneously. One example is volcano monitoring, where rare eruptions trigger many nodes simultaneously to transmit seismic data traces. For such applications, a MAC protocol should exhibit a low overhead both in idle mode and during correlated traffic bursts. Existing MAC protocols only meet one of these requirements, but not both at the same time.
