摘　　要：对物联网高效服务路由的选择,能够有效保障物联网络下的无线传感网络的通信质量。对高效服务路由的优化选择,需要对参与节点进行约束,组建新的相遇节点的数据分组机制,完成路由选择。传统方法先组建基于模糊决策理论的时延路由选择模型,定义各目标的优化贴近程度,但忽略了组建新的相遇节点的数据分组机制,导致路由选择精度偏低。提出新的物联网高效服务路由选择方法。该方法先利用分组索引增量交换方法组建无线传感网络路由模型,计算出数据分组传送成功概率,依据经典Epidemic机制得到数据分组从源节点传送到目的节点的概率,对参与数据分组转发的节点进行约束,组建新的相遇节点的数据分组机制,并完成物联网络技术下的高效服务路由选择。仿真证明,所提方法路由选择成本较低,为保障物联网络的服务质量奠定了基础。This paper presents a selection method of new efficient service routing in Internet of things. The group- ing index increment exchange method is used to build wireless sensor network routing model, and success rate of data packet transmission is calculated. According to classical Epidemic mechanism, probability of data packet transmitting from source node to destination node is obtained, then nodes involved in forwarding data packet are constrained, and new data packet mechanism of encountered nodes is built. Finally, the routing selection of efficient service in Internet of things is completed. Simulation results show that the proposed method has low cost routing selection. It lays the foundation for the service quality of Internet of things.
