PERFORMANCE IMPROVEMENT OF CLUSTERED NETWORK THROUGH DATA REPLICATION AND SECONDARY CLUSTER HEAD SELECTION

Abstract

The objective of the proposed system is to augment the efficiency of the clustered wireless sensor network using Game theoretic approach. In WSN the Cluster Head (CH) has the responsibility of gathering data from the members of its group and transmitting it to the sink. In this approach CH is selected by taking into consideration the residual energy. A periodical change of the head happens when the CH energy drops below the energy of other nodes present in the same cluster. Data replication is done if either CH fails to work or the link between CH or sink gets disconnected.
