Abstract |
|
Wireless Sensor Networks consist of small, low-power, low-energy nodes used for monitoring environmental parameters such as temperature, humidity and motion. The sensor nodes run on batteries that are not recharged during the network’s lifetime. Therefore, increasing WSN lifetime is a significant problem. In this article, We propose an improvement on the LEACH routing protocol to decrease energy consumption and increase network lifetime. Modified LEACH selects the cluster head node not only by considering residual energy of the node greater than the average residual energy level of nodes in network, but also on the basis of the distance between the candidate sensor node to the BS as a key parameter. The results of simulation show our proposed algorithm outperforms Basic LEACH protocol in terms of throughput and network lifetime. |
