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.
