The effects of an Adaptive and Distributed Transmission Power Control on the performance of energy harvesting sensor networks

摘要: Abstract The design of routing protocols for wireless sensor networks (WSNs) has been traditionally tackled by assuming battery-powered sensors, in which minimizing the power consumption was main objective. Advances technology and ability to harvest energy from environment enabled self-sustaining systems thus diminish significance network lifetime considerations WSNs. Although WSNs operated energy-harvesting sensors are not limited lifetime, they still pose new challenges due unstable uncertain amount that can be harvested environment. In this paper, we propose a protocol uses adaptive transmission maintain connectivity, distributes traffic load on network. Based local information, each node dynamically adjusts its order maximize network’s end-to-end performance. simulation results indicate proposed keeps connected at most times using an efficient management, outperforming greedy forwarding dynamic duty cycle terms packet delivery ratio, delay, management.
