A new LEACH-based routing clustering protocol in WSN

Aiming at the disadvantages of LEACH protocol, a new multi-hop WSN cluster routing protocol was proposed, realizing the purpose of saving energy. The election of each cluster heads is on the basis of the residual energy of the node and the distance between the node and the base station. The non-cluster head nodes has taken into account of factors, such as Received Signal Strength Indicator (RSSI) and the energy of cluster heads joining the cluster. A method of establishing a hierarchical routing tree with hop count is used for data transmission, the count which is obtained with division area by fixed energy-broadcast message. Results of simulation indicate that the improved protocol can balance the network load and enhance the network operation cycle. © 2013 Binary Information Press.
