Battery life is a very precious resource in sensor networks to provide high-quality multimedia communications among wireless nodes. For reducing power consumption and satisfying QoS requirements, we propose a routing scheme with efficient power management and on-demand quality control for wireless sensor networks. Two cost functions are developed to minimize the transmitting power and maximize the link quality under the constraint that an end-to-end frame error probability should be met. The heuristic problem on minimizing power consumption under frame error constraints can be derived as a closed-form solution in this paper. Therefore, an optimal route can be rapidly determined by accurately calculating the power requirement for each sensor node. Finally, our analytical results indicate that the proposed scheme is superior to a previous work with the same constraint and is also comparable to the results obtained from a heuristic simulation.
