Extended energy model for the low rate WPAN

Energy efficiency is a major concern in wireless sensor networks (WSNs) and as such power control policies play an essential component in maximizing a network´s lifetime. Optimal power control policies provide the correct trade-off in balancing packet transmission reliability within the operational environment with expanded energy based on the wireless transceiver characteristics. In this paper, an extension of an energy model previously developed for the Chipcon CC2420, an IEEE802.15.4trade device, is presented. The approach provides an extended energy model taking into account transitions energy cost between the Chipcon CC2420 operational states. The empirical testbed used to obtain the measured data is presented along with a summary of the measurements. A comparison is made between the extended model and the previous model to illustrate the importance of incorporating the transition energy requirements
