摘要

A Wireless Sensor Network (WSN) provides a significant contribution in emerging fields such as ambient intelligence and ubiquitous computing. In WSNs, the optimization and the load balancing of network resources are a critical concern to provide intelligence for a long duration. Since the clustering of sensor nodes can significantly enhance the overall system scalability and energy efficiency of the network, this paper presents a distributed energy-efficient clustering-based hierarchy protocol to achieve the network longevity in WSN. Indeed, the proposed algorithm partitions the network evenly into different clusters based on the size of cluster, the transmission power, and the energy level of nodes with one node acting as a cluster head (CH). Additionally, the routing paths between CHs are dynamically formed using a geographical and energy aware neighbors' selection to achieve inter-clusters communication. Finally, the intra-cluster scheduling is the last major issue related to the setup phase. Simulation results show clearly that our scheme reduces the overall energy consumption of the network and improves its lifetime compared to other energy-saving-based mechanisms.
