A survey and comparative study on different energy efficient MAC-protocols for Wireless Sensor Networks

Medium access control (MAC) plays a crucial role in energy consumption, bandwidth utilization etc. for long term WSN deployment. An improved MAC protocol can ensure efficiency of energy for low sensing ranges. There are several MAC-Protocols with different objectives. The aim of this paper is to study on some energy efficient MAC-Protocols in Wireless Sensor Network. This paper also takes a closer look at the performance of the MAC-Protocols in terms of energy efficiency in different situation. Lastly this paper draws a conclusion comparing the protocols. In this paper the energy efficiency is given higher priority than latency, throughput etc for comparison.
