Congestion Control in WBAN in the Field of Heterogeneous Network

Abstract: The Wireless Sensor Network (WSN) technology plays a significant role in the present day applications considering energy, security, routing, load balancing, optimization etc. The application of Wireless Body Area Network (WBAN) in recent times has significantly increased the potential of remote healthcare monitoring systems. However, the issues considering the congestion control and the performance of WBAN with respect to energy is still persistent. This paper intends to develop a heterogeneous WBAN network in order to perform congestion control and evaluate the energy efficiency. The control parameters such as distance and the traffic load were also computed which resulted in a more robust analysis on congestion control. Graphs of Cumulative Distribution Function (CDF) vs. traffic load and Probability Density function (PDF) vs. traffic load were given which shows an improved rate in the flow of traffic with respect to congestion control. Evaluation with respect to energy consumption with respect to WBAN nodes is also performed.

Keywords: WSN, WBAN, congestion control, energy efficiency.
