An Improved Equal Hierarchical Cluster-based Routing Protocol for EH-WSNs to Enhance Balanced Utilization of Harvested Energy

Enhancing harvested energy utilization and balancing consumption are the main challenges in designing routing protocols for harvesting wireless sensor networks (EH-WSNs). This paper considers efficient hierarchical cluster-based method enhancing while ensuring balancing, reliability connectivity of EH-WSNs. For these aims, a new protocol EH-WSNs is proposed. contains two phases: cluster-route establishment data transmission. Cluster-route phase including CH selection, next-hop selection joining CMs to proper CH, performed using multi-criteria such as residual energy, distance BS, node adjacency degree, link statistics rate nodes. Moreover, modified sensing radius adjustment scheme introduced further improve balance each from time. In transmission phase, an adaptive power proposed use more effectively considering current predicted ambient environment. improves by mobile sink. Extensive simulations conducted demonstrate that achieves better network performance than other existing
