Enhanced Combined Multiplexing Algorithm (ECMA) for Wireless Body Area Network (WBAN)

Abstract

A wireless body area network WBAN consists of a medical sensor attached to or implanted in the body through a wireless medium. The physical information of the human body can be collected using this technology. The coordinator node collects information from sensor devices. A WBAN consists of sensors that can collect body variables or body related data using wireless medium attached on or implanted in the body through a wireless medium. The WBAN network consists of coordinator nodes that collect information from the sensing device and transfer this information to the healthcare monitoring system through access point (AP) located nearby. One of the challenges in body area network is to maintain the quality of service (QoS), e.g., throughput and delay, under the dynamic environment dictated by human mobility. In this paper, we are improving the performance of MAC protocol in congested wireless networks by combining carrier-sense multiple access with collision avoidance (CSMA/CA) with that of time-division multiple access (TDMA). The system opt functionality to sends this information to the external monitoring system (usually electronic healthcare system) through nearby access points (APs). The challenge with the body area network is to track and maintain the QoS, e.g., throughput and delay, under the dynamic environment dictated by human mobility. IN this paper, we are improving the performance of the MAC protocol in congested wireless networks by combining CSMA/CA with that of TDMA.
