摘要: The limited capacity of battery power becomes one the major constraints in applications Internet things (IoT). Ambient energy harvesting technologies and wireless transfer have appeared to resolve supply problem, making it possible for sensor nodes operate perpetually. In this paper, we focus on efficiency maximization network throughput optimization problems cooperation Energy Harvesting Cooperative Wireless Sensor Networks (EHC-WSNs). order maximize charging phase, a Region-based Proactive Cooperation (RPEC) strategy is developed, which used charge life-critical cooperators or receivers time. By introducing novel metric that converts optimal forwarder selection from multi-dimensional problem one-dimensional an Energy-Neutral-based Opportunistic Routing (ENOCR) algorithm proposed optimize relay improve throughput. Extensive simulations show Mechanism (OECM) can significantly lifetime.
