W F - MCHEL : Fuzzy Based Master Cluster Head Election

Wireless Sensor Network is the network of powerlimited sensing devices called sensors deployed in a region to sense various types of physical information from the environment when these sensors sense and transmit data to other sensors present in the network; considerable amount of energy is dissipated. In this paper, an effort has been done to propose F-MCHEL, a homogeneous energy protocol. In LEACH protocol the clusters are formed randomly on the basis of threshold values; whereas, in the proposed protocol a fuzzy logic approach is used to elect the cluster-head based on two descriptors energy and proximity distance .Out of these elected cluster heads one Master cluster head has been elected .The cluster head which has the maximum residual energy is elected as Master cluster head. In conventional Leach approach all the Cluster heads are used to sends the aggregated information to the base station, however in the proposed protocol only Master cluster head sends the aggregated information to the base station. Simulation results on MATLAB shows that the proposed protocol provides higher energy efficiency, better stability period and lower instability period as compared to LEACH protocol in spite of overhead of election of Master cluster head. Results obtained shows that an appropriate Master cluster-head election can drastically reduce the energy consumption and enhance the lifetime of the network.
