Media Access Control (MAC) layer is a very important layer in Wireless Sensor Network (WSN). MAC layer is a major reason to provide the reliability and efficiency for WSN for accessing the media. Media Access Control (MAC) is responsible for channel access regulations, scheduling, buffer management and error control. In Media Access Control (MAC) they need a MAC protocol to consider energy efficiency, reliability, low access delays and high throughput as major priorities to accommodate with sensor's limited resources and to avoid redundant power consumption. This paper proposes performance comparison of WSN specific MAC protocols with energy efficient features.
