Abstract :
Power conservation is an issue which is to be dealt in sensor networks. The nature of sensor networks and their deployment makes it difficult for the optimal transmit power to be modified after they are deployed so a common transmit power has to be selected in such a way that makes the deployment more feasible and easier. An optimal transmit power can ensure better connectivity and longer battery life. Excessive interference can also be eliminated by choosing a common and minimal transmit power for all nodes. In this paper we have investigated the interference powers introduced due to the different ways of deployments of wireless sensor networks over a certain area and we also used the graphical approach to look at the effects of distance from the central receiving node and densities on the BER and the interference powers while also changing the transmission data rates. We have also investigated the phenomena through simulations and the main aim is to optimize the performance of sensor networks by observing their behavior in various regularly placed deployments.
