Energy efficient cluster head selection algorithm in mobile wireless sensor networks

摘要

In Wireless sensor networks, existing energy efficient routing algorithms assumed that the sensor nodes are stationary. Some of the applications in WSN must combine with both mobile sensor nodes and fixed sensor nodes in the same networks. When mobility is functioned there should be performance degradation. Because these nodes are equipped with a lesser amount of memory, restricted battery power, little computation capability, and small range of communication. So there is a need for energy efficient routing protocol to forward the incoming packet. In this paper, we propose Energy Efficient Cluster Head Selection Protocol in Mobile Wireless Sensor Network (EECHS-MWSN). The cluster-head nodes are selected from the residual energy, lowest mobility factor and density of the node. It is also used that the Gateway nodes are act as an intermediate node to transfer the data to the Base station. Simulation results show that the EECHS-MWSN protocol has more Energy consumption, network lifetime and throughput than the existing LEACH-Mobile protocol.
