An energy-adaptive multiple paths routing approach for wireless sensor networks

摘要: A wireless sensor network (WSN) is expected to have a significant impact on military and civil applications such as target field imaging, intrusion detection, weather monitoring. Sensors are battery-powered, hence energy-conserving communications essential prolong the network's lifetime. Also, given unreliable nature of channels high failure rate individual sensors, fault tolerant routing protocol with energy-efficiency getting more attention. In this paper, we propose an energy-adaptive multiple paths algorithm (EMRA) for networks. It consists three elements: (i) gradients disseminate data over from source sink, (ii) rules used setting up disjoint paths, (iii) policies selecting paths. By limiting maximum number gradients, exploratory messages forwarded decreased efficiently. using sink node can get sufficient which enables EMRA recover quickly. Our analysis simulation results reveal that performs better than existing algorithms in terms average dissipated energy delay set
