Energy efficient scheme based on low energy adaptive clustering hierarchical protocol for wireless sensor network

Energy is the key concern area in Wireless Sensor Networks due to lack of power source, maximum energy is used in transmission of data. This paper proposes a new routing approach based on hierarchical routing protocol LEACH where clusters are refreshed periodically based on remaining energy and distance. We propose that the network area in Q-LEACH protocol on the basis of dividing whole network into four quadrants and each quadrant performs individually. In LEACH-E protocol, all nodes have same energy and same probability of suitable the cluster head. After the first round, energy level of each node changes and then the amount of residual energy of each node is used to select cluster head nodes. The nodes with highest residual energy are chosen on rest of the nodes. In this protocol, cluster head (CH) selection is based on the highest energy by the base station.
