An Energy Efficient Hybrid routing for Wireless Sensor Network using Fuzzy Logic

Wireless Sensor Networks is a collection of sensor nodes and base station. The nodes have limited battery power. The efficient utilization of sensor node’s energy, clustering is one of the powerful tool. The heterogeneous wireless sensor networks consist of different type of sensor nodes in term of sensing, computation, communication and power. The proposed protocol is An Energy Efficient Hybrid routing for Wireless Sensor Network using Fuzzy Logic provide the multi path routing among the Cluster Head of super node region for transmitting the data to base station. The proposed protocol is efficient for selecting an optimum (cluster head) CH for transmission of data. The proposed Fuzzy Logic Technique, the status of the CH node is verified to transmits the data to base station. The designed fuzzy logic controller determines, best outcome from all the possible combinations of noise, load and residual energy. The CH node with highest Output Membership status will be chosen to send the data to base station . The proposed protocol improved the throughput of network. This increases the stability period of network. The Simulation result shows the improvement of the overall network performance in terms of stability period, alive nodes.
