Lower power RF transceiver modeling and design for wireless microsensor networks

The design of wireless microsensor systems has gained increasing importance for a variety of civil and military applications. With the objective of providing short-range connectivity with significant fault tolerance, these systems find usage in such diverse areas as environmental monitoring, industrial process automation, and field surveillance. The main design objective is to, maximize the battery life of the sensor nodes while ensuring reliable operations. To achieve this goal, the microsensor node has to be designed in a highly integrated fashion and optimized across all levels of system abstraction. For microsensor networks, the RF transceiver dominates the power consumption. The concept of transceiver power efficiency is introduced, which defines the ratio of RF transmit power to transceiver electronics power, to show that short-range RF transceivers have low transceiver power efficiency. A system energy model is developed to show that the battery life of the transceiver not only depends on its power consumption, but more importantly, on its energy dissipation over the operation cycle.
