Abstract

This project investigates energy usage in three energy-efficient WSN MAC protocols (AS-MAC, SCP-MAC, and Crankshaft) on TelosB wireless sensors. It additionally presents BAS-MAC, an energy-efficient protocol of our own design. Our evaluations show that in single-hop networks with large send intervals and staggered sending, AS-MAC is best in the local gossip and convergecast scenarios, while SCP-MAC is best overall in the broadcast scenario. We conjecture that Crankshaft would perform best in extremely dense hybrid (unicast and broadcast) network topologies, especially those which broadcast frequently. Finally, BAS-MAC would be optimal in networks which utilize hybrid traffic with infrequent broadcasts, and where broadcasting is performed by motes that do not have an unlimited power source.
