Medium Access Control in Wireless Sensor Networks [chapter]

Wei Ye, John Heidemann
Wireless Sensor Networks  
This paper reviews medium access control (MAC), an enabling technology in wireless sensor networks. MAC protocols control how sensors access a shared radio channel to communicate with neighbors. Battery-powered wireless sensor networks with many nearby nodes challenge traditional MAC design. This paper discusses design trade-offs with an emphasis on energy efficiency. It classifies existing MAC protocols and compares their advantages and disadvantages in the context of sensor networks. Finally,
