摘　　要：电力物联网前端传感器网络受到应用场景的多样性,适宜采用自组织网进行数据传输,针对移动自组织网中网络路由可靠运行性和QoS保证问题,提出了一种基于模糊理论的节点信誉度评估模型,在此基础上建立跨层的多参数QoS路由模型。模型利用节点参数信息评估直接信誉度,通过邻居节点的推荐值计算间接信誉度,最后对直接、间接信誉度进行权重修正得到节点综合信誉度。利用该信誉度模型对网络节点进行评估,提出一种节点独立的多径路由协议RMQR。协议中只有目的节点应答路由请求,中间节点仅转发RREQ到可信节点。经过仿真表明,对比AODV和DSR协议,RMQR可以发现和有效抑制自私节点,实现网络负载均衡,有效提高移动自组织网的可靠性和容错性。Aiming at the reliability and security problems in Mobile Ad hoc networks,a reputation evaluation model based on fuzzy theory was proposed.On this basis,a cross-layer multi-parameter QoS routing model was established.The direct reputation was evaluated by nodes’parameter information and the indirect reputation was obtained from neighbor nodes’recommendations.The direct reputation and indirect reputation were combined with weights to obtain the node’s comprehensive reputation.On this basis,nodes were evaluated with the reputation model and then a reputation-based multipath QoS routing protocol(RMQR)was proposed.In this protocol,only the destination node can respond to the route request(RREQ),and intermediate nodes only forward RREQ to trusted nodes.Simulation results show that RMQR can accurately discover and suppress selfish nodes,realize the load balance of network services,and thus effectively improve the reliability and robustness of MANET,which also proves the validity and rationality of the reputation evaluation model.
