An Energy Efficient Protocol Based On Clustering In Wireless Sensor Networks

R.Shakila, S.Ananthakumaran

Wireless Sensor Networks (WSN) are one of the most rapidly developing technologies with a wide range of applications which includes a sensing process, security providence and environmental sensing and military applications. WSN consists of collection of sensor nodes and each sensor nodes are used for sensing the environmental conditions while transmitting data to the base station. Energy consumption is the major issue in WSN. Each sensor nodes can utilize only limited amount of power supply for performing transmission of packets in a wireless environment. Saving Energy and Clustering Algorithm (SECA) is a clustering based algorithm which is mainly used to reduce the energy consumption in each Cluster Head (CH). Clustering is one of the promising techniques for reducing the energy consumption. In a clustered WSN, sensor nodes are partitioned into a certain number of clusters, each of which has a cluster head (CH) and some non-cluster head members. CH collects information from all the cluster members and then forwards to other CH. while non-CHs are responsible for sensing environmental conditions and transmitting information to the corresponding CH. CH will change periodically based on the residual energy available with the nodes in the cluster. SECA algorithm is designed based on the existing LEACH protocol to increase the network lifetime and reduce energy consumption in WSN
