Leach Protocol

In order to prolong the lifetime of wireless sensor networks, improvement of cluster-head selection mechanism based on LEACH protocol is proposed. To make the energy distribution more uniform, we consider the relationship of the density of nodes, residual energy of nodes and distance between nodes and Sink node. It eliminates the defect of energy consumption imbalance in the network caused by random position of cluster-heads and the problem of premature death of nodes caused by low energy nodes becoming cluster-heads. Simulation results show that compared with LEACH algorithm, the improved algorithm extend the network lifetime.

Leach Protocol

In WSNs, the only source to save life for the node is the battery consumption. During communication with other area nodes or sensing activities consumes a lot of power energy in processing the data and transmitting the collected/selected data to the sink. In wireless sensor networks, energy conservation is directly to the network lifetime and energy plays an important role in the cluster head selection. A new threshold has been formulated for cluster head selection, which is based on remaining energy of the sensor node and the distance from the base station. Proposed approach selects the cluster head nearer to base station having maximum remaining energy than any other sensor node in multi-hop communication. The multi hop approach minimizing the inter cluster communication without effecting the data reliability.
