Abstract: Aiming at energy balance routing problem in rechargeable wireless sensor network (WSN), a new multi-path routing algorithm and an opportunistic routing algorithm are proposed in the scenario of stable power wireless charging and monitoring data collection network, so as to achieve the purpose of energy balance in the network. The relationship between the charging and receiving power of wireless sensor nodes is constructed by the theory of electromagnetic propagation. Considering the sending and receiving energy consumptions of wireless sensor nodes in the network, the energy balance routing problem is transformed into the max-min optimization problem of the lifetime of the network. The link traffic obtained by the linear programming is used to guide the data flow allocation in the routing. Then consider a more realistic scenario of low power WSN and propose an energy equalization routing algorithm based on opportunistic routing. The experimental results show that the proposed routing algorithm can effectively improve the utilization ratio of the energy collected and the lifetime of the network in the working period compared with the routing method of the contrasting object.
