【 摘 要 】

Wireless Sensor Network consists of large number of Sensor Nodes. The main aim is to increase the lifetime of the network as the sensors are deployed mainly to perform unattended operations like Environment Monitoring, Scientific activity Detection, Industrial Monitoring and Control etc. All these activities require Robust Wireless Communication Protocol with low power consumption. Cluster Based Protocol is purposed with two important changes, first is minimum distance, maximum residual energy, minimum distance used to selected the CH (Cluster Head) instead of probability as used in the LEACH, so that it can be used for the sensor nodes with different initial energy among the sensor nodes so that energy is optimally consumed for the cluster members to interact with Cluster Heads. The role of the Cluster Head is rotated so that the energy consumption can be distributed evenly and the lifetime of the Wireless Sensor Network can be extended. Secondly it selects optimal path and adopts multi hop communication between cluster head and sink is presented here. Experimental results show that the life time of the network is extended as compared to other approaches.
