Energy conservation is the major concern of Wireless Sensor Networks, as the energy is the determining factor of the network lifetime. The reason is that the energy level of sensors has a great impact on the network lifetime. Several mechanisms have been proposed to minimize the energy consumption of nodes. In this paper, a cluster based, trustworthy topology management mechanism is presented and is proved to be energy efficient. The entire work relies on three important phases and they are cluster formation, chief node selection, trust degree computation and node’s state control. The cluster is formed by taking the location coordinates into account. This is followed by the selection of chief node. The chief node is responsible for computing the trust degree and to control the state of the constituent nodes. As limited count of nodes is involved in the process, the lifetime of the network is considerably improved. Finally, the proposed work is tested for its efficacy and the experimental results are satisfactory with respect to network lifetime.
