Survey on Energy Efficiency MAC Protocols in Wireless Sensor Network

Abstract

One of the dynamic and active research area for researchers is on Wireless sensor networks (WSNs) It is popular worldwide in the real time application such as Tracking target and tracking, monitoring in the field of environmental and industrial issues. Usually, deployed nodes work with restricted energy resources.So the parameter energy efficiency becomes one of the objects of exercise for these sensor nodes in the networks. To make WSN more energy efficient, researchers have developed quite a large number of MAC protocols. In this paper, description of various energy efficient MAC protocols of WSNs in three categories: contention based, scheduled based, hybrid arepresented emphasizing their strengths and weaknesses. Design proposed by various MAC protocols is discussed. Comparison study is made with various protocols on attributes.
