An Energy Efficient Clustering Method for Wireless Sensor Networks

چکیده
Wireless sensor networks have many sensor nodes with a limited energy in a limited area. One of key issues in wireless sensor networks is to prolong the network lifetime. In this paper, we propose a scheme to construct an energy-efficient cluster structure in wireless sensor networks. Our scheme considers both the residual energy of sensor nodes and the number of neighbors around each node when selecting cluster heads. Simulation results show that our scheme can successfully prolong network lifetime by evenly distributing energy consumption over all sensor nodes. Key-Words: wireless sensor networks, clustering, energy efficiency, energy-aware, neighbor-aware, network lifetime

An Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
