为解决现有依赖具体链路探测包的物联网路由方案易遭受干扰的问题，给出了一种基于虚拟网络估计的物联网路由方案。所给方案首先利用网络状态矢量和活动共享估计每条链路的成功传输数据率，然后根据节点局部产生流量、邻居节点的流入流量和重传流量估计节点流量，最后选择能够增加网关流量的节点作为下一跳节点，并按照这一原则建立物联网路由。仿真分析结果表明，所给路由方案估计的传输数据包数与仿真实验结果一致，并且所给路由方案的吞吐量优于基于负载感知的物联网路由方案。因此，所给路由方案可以很好地用于寻找物联网的有效传输路径，具有较好理论研究价值和实际推广应用价值。

Research on internet of things routing scheme based on maximizing gateway traffic

In order to solve the problem that existing internet of things routing schemes relying on specific link detection packages are vulnerable to interference, an internet of things routing scheme based on virtual network estimation is proposed. Firstly, the proposed scheme uses the network state vectors and the activity sharing to estimate the successful transmission rate of each link. Secondly, the traffic of the node is estimated according to the local traffic generated by the node, the inflow traffic of the neighbor node and the retransmission flow. Finally, the node that can increase the gateway traffic is selected as the next hop node, and the internet of things routing is established according to this principle. The simulation results show that the number of the data packets estimated by the proposed scheme and the simulation results are consistent, and the throughput of the proposed routing scheme is superior to that of the load-aware routing scheme. Therefore, the proposed routing scheme can be well used to find the effective transmission path of the internet of things, which has good theoretical research value and practical application value.
