SLEEP SCHEDULING MECHANISM IN INTER-CLUSTER COMMUNICATION FOR WSN

Wireless Sensor Network is easy to configure and deployment of network is also simple. It is very useful in gathering the information. As sensor device are small in size and it is operated by the battery which once die is not rechargeable, so minimizing energy consumption and node death rate is challenging issues in WSN. Once node die it can’t take part in information gathering which is not good for the overall system performance. Making cluster is a way to reduce the energy consumption in WSN by making cluster head which only communicate with base station and rest of the node communicate with cluster head, because distance is major factor for energy consumption in transmission of data. Wireless Sensor Network need more improvement and hence proposed intra and inter-cluster communication with sleep/active rate of node in WSN. Author establish a tradeoff between active node and energy consumption because if more node in sleep state then for achieving the target packet failure probability or error free communication all node take more energy take part in Sub-cluster head communication or more hop-distance communication with more energy. Result in terms of network life time, energy consumption, node decay rate and communication overhead shows that presented work performed well when compare with existing technique.
