This paper introduces a novel energy-efficient routing algorithm designed to enhance the performance of Wireless Sensor Networks (WSNs) by incorporating mobile sink support. WSNs are widely deployed in diverse applications, ranging from environmental monitoring to surveillance, where energy efficiency is crucial for prolonged network lifetime. The proposed algorithm aims to mitigate energy consumption disparities among sensor nodes by dynamically adapting the network topology through the introduction of a mobile sink.

The algorithm utilizes an intelligent approach for sink mobility, strategically relocating the sink node based on network conditions and energy levels of sensor nodes. The routing protocol employs a combination of distance metrics and residual energy information to optimize the path selection process, ensuring balanced energy utilization across the network. The mobility of the sink facilitates efficient data collection, reducing the energy burden on sensor nodes and prolonging the overall network lifetime.

The paper presents a comprehensive analysis of the proposed algorithm’s energy efficiency, including simulations and performance evaluations. Comparative studies against traditional routing protocols underscore the advantages of the energy-efficient algorithm, demonstrating its efficacy in achieving prolonged network operation and reduced energy consumption.
