Abstract

As an enabling network technology, energy efficient Medium Access Control (MAC) protocol plays a vital role in a battery-powered distributed sensor network. MAC protocols control how sensor nodes access a shared radio channel to communicate with each other. This chapter discusses the key elements of MAC design with an emphasis on energy efficiency. Furthermore, it reviews several typical MAC protocols proposed in the literature, comparing their energy conservation mechanism. Particularly, it presents a Collaborative Compression Based MAC (CCP-MAC) protocol, which takes advantage of the overheard data to achieve energy savings. Finally, it compares the performance of CCP-MAC with related MAC protocols, illustrating their advantages and disadvantages.
