Power Adaption Routing Protocol For Realtime Applications In Wireless Sensor Networks

One of the most important and challenging issues in real-time applications of resource-constrained wireless sensor networks (WSNs) is providing end-to-end delay requirement. Many wireless sensor network (WSN) applications require real-time communication. In order to address this challenge, we propose the Power Aware Routing Protocol, which attains application-specified communication delays at low energy cost by dynamically adapting transmission power and routing decisions. Extensive simulation results prove that the proposed Protocol attains better QoS and reduced power consumption.
