DA-MAC: Density Aware MAC for Dynamic Wireless Sensor Networks

Abstract : The paper presents DA-MAC, a density aware access method for efficient forwarding in multi-hop dense wireless sensor networks. Its principle is to offer a configurable channel sensing phase during which nodes request transmission opportunity in a way that avoids collisions. The receiver can thus schedule transmissions so that nodes may return to sleep and only wake up at their scheduled transmission instants. Allowing burst transmissions improves network capacity and the network can handle load fluctuations. The paper presents simulation results on the performance of DA-MAC compared with two other adaptive access methods: B-MAC with Contention Window and SCP-MAC. They show excellent performance of DA-MAC with respect to latency, packet delivery ratio, and power consumption.
