Deployment of the nodes in a wireless sensor network to satisfy continuous sensing with extended network lifetime while maintaining uniform coverage in the deployment region is the major challenge in wireless sensor networks. Various architectures and node deployment strategies have been developed for wireless sensor network, depending upon the requirement of application. Node deployment in wireless sensor network is application dependent and can be either deterministic or randomized. In this paper we present the relation between the energy consumption and the deployment strategy. We present a comparative investigation of the random and grid deployment strategy of the sensor nodes in wireless sensor networks based on energy consumption. We have also compared the energy consumption by the few commercially used chipsets based on two deployment strategies.
