A Paper on Implementation of Adaptive Load Balancing Technique in E-Leach?

In Wireless Sensor Networks (WSNs), minimizing energy consumption of available resources remains unsolved. To reduce power consumption many types of routing protocols have been developed. In these protocols, cluster-based routing protocols are found to be more energy efficient. In cluster-based routing, a cluster head is selected to aggregate the data received from root nodes and forwards these data to the base station. The selection of cluster heads should be efficient to save energy. In our proposed protocol, we use E-LEACH (Low energy adaptive clustering hierarchy) protocol with ALB (Adaptive load balance) technique where E-LEACH improves the performance of basic LEACH protocol whose aim is to elect the cluster-head on the basis of remnant energy of sensor node in WSN and ALB avoids congestion. The proposed routing protocol works efficiently in large as well as small areas. For an optimal number of cluster head selection we divide a large sensor field into clusters. For efficient communication between a base station and cluster heads these clusters are further grouped into zones. We perform MATLAB simulations to observe the throughput, average jitter, energy consumption, end-to-end delay and network lifetime. Our proposed ALB routing protocol outperforms in large areas in comparison with the E-LEACH and E-LEACH with TSP routing protocols.
