Comparison, evaluation and characterization of MAC protocols in Wireless Body Area Network

The advancement in technology, Wireless Body Area Network (WBAN) is one of the increasing interests for various purpose, such as health monitoring, defense, sports etc. by the help of inbuilt human body-sensor networks. Wireless body area network monitoring by used to supervise vital signs sensor node of human body in or around the outside body. This paper analysis the main characteristics of MAC protocol for used in body wireless network. The most common protocols for Wireless Body Area Network (WBAN) is S-MAC TMAC, ZigBeeMAC, Baseline-MAC protocols. Here study and survey of these MAC Protocols in WBAN regarding to characteristics of these Protocol. After that simulation of these MAC protocol and what we find out the result after simulation is described in the paper. Here consider the main factor of MAC protocol is energy efficiency, latency, throughput, transmission packet rate, receiving packet rate, fade-depth distribution and many other objective factors. The simulations are conducted by Castalia 3.2 simulator under the environment of Omnet++4.5 as like on human body in different scenarios. After analysis, comparison, and evaluation to conclude which MAC protocol is best other than comparison MAC protocol in different point of view.
