Performance Analysis of MAC Layer Protocols in Wireless Sensor Network

Access Control (MAC) layer protocols have a critical role in making a typical Wireless Sensor Network (WSN) more reliable and efficient.Choice of MAC layer protocol and other factors including number of nodes, mobility, traffic rate and playground size dictates the performance of a particular WSN.In this paper, the performance of an experimental WSN is evaluated using different MAC layer protocols.In this experiment, a WSN is created using OMNeT++ MiXiM network simulator and its performance in terms of packet delivery ratio and mean latency is evaluated.The simulation results show that IEEE 802.11MAC layer protocol performs better than CSMA, B-MAC and IEEE 802.15.4 MAC layer protocols.In the considered scenario, IEEE 802.15.4 is ranked second in performance, followed by CSMA and B-MAC.
