Energy Efficient Cluster based routing in MANET

Energy efficient cluster formation of nodes in Mobile Ad-Hoc Networks (MANETs) is very important as nodes in MANETs typically operate unattended with a limited power source. Cluster based routing protocols in MANETs must minimize the energy costs in nodes due to message passing during cluster formation. In this paper, we propose a “Signal and Energy Efficient Clustering (SEEC)” algorithm based on signal strength and energy level of nodes in MANET to improve system performance. The algorithm focuses on cluster head formation and maintenance, and prevents death of cluster head by making another cluster node as the cluster head when power level falls below certain threshold value.
