A Wireless Sensor Network (WSN) consists of tiny sensor nodes capable of sensing some physical attribute, processing and communicating to other nodes in the network. WSNs are very much applicable for health tracking, environmental monitoring, soil monitoring etc. Energy is a major constraint in Wireless Sensor Networks. Medium Access layer is one of the means to conserve the limited energy. This paper analyzes and compares different types of MAC protocols in Wireless Sensor Networks
