Enhanced cluster based routing protocol for mobile nodes in wireless sensor network

Mobile Wireless Sensor Networks (MWSNs) are a current encouraged technology which is used to help many civilian, military and industrial services. Energy saving is the critical issue while designing the wireless sensor networks. In order to enhance the network life time there are many routing protocols have been developed. One of these is clustering based in which network is partitioned into small clusters and each cluster is examined and controlled by a single node called Cluster Head (CH). In this paper, we propose an enhanced algorithm for Low Energy Adaptive Clustering Hierarchy-Mobile (LEACH-M) protocol called ECBR-MWSN which is Enhanced cluster based routing protocol for mobile nodes in wireless sensor network. ECBR-MWSN protocol selects the CHs using the parameters of highest residual energy, lowest Mobility and least Distance from the Base Station. The BS periodically runs the proposed algorithm to select new CHs after a certain period of time. It is aimed to prolonging the lifetime of the sensor networks by balancing the energy consumption of the nodes. Then compare the performance of our proposed algorithm with the cluster based protocols using ns2 simulator. The simulation result indicates that the proposed algorithm gives better performance in terms of higher packet delivery ratio, throughput, energy consumption, routing overhead, and delay.
