Fuzzy Logic Based Energy Efficient Network Lifetime Optimization in Wireless Sensor Network

摘要

Energy conservation is prime issue for wireless sensor network due to their limited battery life. Energy losses are occurring mostly on the edges of wireless sensor network, where most of the packet drops are occurred. In order to avoid this energy loss problem this paper has introduced concept of advance/ super node which can be deployed at edges of the network or inside to the network. For the cluster head selection both the methods e.g. clustering technique and direct communication are employed to minimize energy consumption loss. Proposed algorithm is improved form of E-zone model. The simulation is done with the help of MATLAB toolbox and result shows that our proposed model is better in terms of energy saving, reaming alive nodes and improved network lifetime for Wireless Sensor Network.
