Energy Conservation in Wireless Body Area Network Using Optimal Route Selection and Node Configuration

Wireless body area networks (WBAN) are becoming increasingly popular nowadays due to their wide range of applications, particularly in the field of healthcare systems. In the medical field, a WBAN is frequently used to collect biomedical signals and monitor vital signals from a patient on whose body sensors are placed at points of interest. In WBAN applications such as disease analysis, diagnostic monitoring and tracking, a number of hardware and software factors must be considered. Optimization of energy consumed by a WBAN is a significant problem that should be addressed especially when its application is in mobile or outdoor environments where batteries are the main source of power. In this paper, an optimal route selection and node configuration method (ORS-NCM) is proposed to reduce energy consumption. It finds an optimal route by considering all the related metrics and also maintains the link stability to prolong the network lifetime. The proposed ORS-NCM scheme is implemented using MATLAB simulation tool, and its results are compared to the state-of-the-art Energy Optimized Congestion Control Based Temperature Aware Routing Algorithm (EOCC-TARA). In terms of energy consumption, latency, throughput, and hop count, simulation results show that ORS-NCM exhibits better performance than EOCC-TARA in delivering packets from source to the destination.
