Abstract

A Wireless Body Area Network (WBAN) is considered as a special type of a Wireless Sensor Network (WSN) with its own challenges and requirements. A traditional WSN is designed to achieve higher efficiency, however, WBAN is designed to achieve maximum throughput, minimum delay and to maximize the energy efficiency, all together. Our analysis indicates that available protocols for WSN are not easily portable for WBAN, specifically Medium Access Control (MAC) Protocols. Thus, we have proposed a new WBAN MAC Protocol based on Aloha protocol which differentiates and preferred various types of traffic based on emergency case. The proposed protocol has been simulated using different scenarios and the obtained results are analyzed and compared using NS-2 Simulator.
