An Energy Efficient Dual Sink Protocol for Wireless Body Area Networks

The growing demand for energy-efficient solutions in Wireless Body Area Networks (WBANs) calls for innovative protocols that can optimize energy consumption while ensuring high network performance. This paper introduces the energy-efficient dual sink protocol (EEDSP) designed to enhance the performance of WBANs through a combination of advanced energy management and reliable communication techniques. EEDSP operates with a dual-sink architecture, utilizing any-casting to ensure optimal data routing while minimizing packet loss and communication delays. The protocol also integrates energy-aware routing mechanisms, which dynamically select paths based on residual energy and distance, extending the network's lifetime. Extensive simulation results demonstrate that EEDSP outperforms existing protocols, such as CRPBA and EEDLABA, in key performance metrics, including PDR, network lifetime, residual energy, end-to-end delay, path loss, and CCR. These results confirm EEDSP as a promising solution for energy-efficient WBANs, making it well-suited for applications in healthcare and other energy-constrained environments.
