Energy Efficient Approach for Wireless Sensor Network: A Survey
Keywords:
Clustering, Energy Efficiency, LEACH, Cluster Head, LifetimeAbstract
Energy Efficiency is the major issues in wireless sensor network (WSN). Hierarchical routing protocol or
clustering is the best solution for reducing energy consumption in WSN. LEACH (Low energy Adaptive clustering
Hierarchy) is good hierarchical protocol .There are many protocols based on LEACH but still have issue of energy
efficiency. In this paper we have mention how to increase energy efficiency of WSN. There are lots of works going on for
the Cluster Head selection for increase network lifetime. If Cluster head (CH) is properly selected then efficiency of the
particular cluster is increase and due to this efficiency of the network will increase. In this paper survey of different
method to improve energy efficiency of wireless sensor network is given.
