【摘要】 针对反向散射通信中无源节点传输范围不同，获得能量不同的问题，提出一种能量优化路由协议(EORP),实现较短路径下节点间的能量均衡。为无源节点调整转发区域，降低转发冗余；动态调整路由度量的权重，实现不同区域能量均衡性和有效性的权衡；划分稳定区域，通过稳定点和备用点之间的协作进一步降低能量消耗。实验结果表明，与AODV和RCRP相比，EORP能有效地延长网络生存期，降低剩余能量方差和能量消耗，提高网络吞吐量。更多还原

【Abstract】 To solve the problems of different backscattering transmission ranges and different energies obtained by passive nodes of backscatter communication, an energy-optimized routing protocol(EORP) was proposed, which achieved energy balance with shorter paths. Different forwarding areas for nodes were selected to reduce forwarding redundancy. Routing metrics weights were dynamically adjusted to achieve tradeoff between energy balance and energy efficiency in different regions. The stable area was divided and the energy consumption was further reduced through the cooperation between stable nodes and standby nodes. Simulation results show that compared with AODV and RCRP, EORP can effectively prolong network lifetime, reduce residual energy variance and energy consumption, and improve network throughput.更多还原
