Backgrounds/Objectives: Method/Statistical Analysis: The objective is to determine an energy efficient, MAC protocol for wireless sensor networks. All the sensor nodes communicate through a Medium Access Protocol (MAC). Energy is wasted while communicating data among sensor nodes. Since wireless sensors nodes are unwired they do not have any means of external power supply and it is only battery operated. Hence designing energy efficient MAC Protocol to expand battery span is very important. A thorough survey on various contention based and hybrid protocols has been done in this paper. Findings: Hybrid MAC Protocol implements the combined advantages of CSMA and TDMA. A clear comparison of some of the best Hybrid MAC protocols and contention based protocols has been explained in this paper. Applications: Based on the performance of various MAC protocols, it is found that contention based MAC protocols can be implemented for low traffic level networks, hybrid MAC protocols can be implemented for high traffic level networks including industrial critical processes.
Keywords: Energy Efficiency, Latency, Packet Delivery, Throughput
