Description

This item was taken from the IEEE Conference ' Queue and power control for rechargeable sensor networks under SINR interference model ' Renewable energy sources can be attached to sensor nodes to substantially improve the performance of sensor networks. In networks with renewable energy sources, conservative energy expenditure may lead to missed recharging opportunities due to the batteries being full, while aggressive usage of energy may cause the network to be intermittently disconnected and reduction in coverage. Thus, new techniques and algorithms must be developed for networks with replenishment to balance these seemingly contradictory goals. In this paper, we consider an uplink wireless senor network with renewable energy sources attached to sensor nodes under the SINR interference model, where the achievable transmission rate of each sensor node depends on its SINR. We develop a provably efficient solution to maximize the total sensing rate subject to quality of service constraints.
