EH-SCSD: A Semi Centralized and Semi Distributed Clustered Routing Algorithm Based on EHWSN

Wireless Sensor Networks (WSN) play a important part in collecting and transmitting information. However, the limited energy supply of sensor nodes poses a significant challenge to the longevity and performance of these networks. Energy Harvesting Wireless Sensor Networks (EHWSN) have been proposed as a solution to this problem. This paper presents a novel routing algorithm for EHWSN with the aim of improving energy efficiency, stability, and reliability. Initially, a centralized approach is employed, utilizing the k-means algorithm for clustering and genetic algorithms for optimizing cluster head routing. Subsequently, a distributed approach is employed to replace cluster heads if their energy levels fall below the predetermined threshold. Simulations conducted in MATLAB showcase advantages over conventional routing algorithms in terms of prolonging the lifespan of networks and enhancing energy utilization.
