Abstract

In MANETs, development of an energy efficient routing protocol is essential. The cost of the network depends on the energy consumption of each mobile node. Overutilization of energy by a mobile node cannot contribute to the utility of the network as a whole. In order to optimize the utilization of energy at each node, we propose an Energy efficient Clustering using PSO and Fuzzy logic for Hybrid MANETs (EC-PFHM). It can minimize the energy consumption and increases the network lifetime. In our proposed approach, an energy efficient cluster head selection is performed using particle swarm optimization (PSO), where the nodes with high residual energy and connectivity are elected as cluster head (CH). Appropriate super cluster head (SCH) is selected by using fuzzy logic. By this the overall networks overhead is reduced and hence the QoS of the network is enhanced. The result obtained through NS-2 simulation shows that the proposed algorithm performs better than FQ-MP-OLSR and BPSO-TORA approaches in terms of reduced energy consumption, delay and increased throughput.
