Abstract

Wireless sensor network is the group of sensor nodes that may be in a well-defined manner or may be in
any fashion performs the function related to the environment by sensing the environment through sensor
nodes and transfer the data forward to the sink for taking the necessary decisions. Due to the random and
thickly distributed it is difficult to recharge or to replace the battery of a node or even the node. For this
reason the major design challenge for this is the energy efficient for these networks. In this paper a new
approach of selecting the cluster head for sending the data to the base station has been proposed. The
selection of cluster head is based on the distance between the nodes and that value is updated into the
routing table of the target node. Then the residual energy is considered for the selection of cluster head .
then the packet loss is taken into the consideration if the nodes are having same residual energy and at last
he trust factor is taken into the consideration for the selection of cluster head .The performance of
proposed algorithm compared with other known algorithm is shown .
