Internet-of-things ad hoc network maneuvering routing selection method based on channel competition mechanism

The invention discloses an Internet of Things ad hoc network maneuvering routing selection method based on a channel competition mechanism. The method comprises the following steps: when an intermediate node receives a network access request message, determining a channel competition estimated value according to the trying forwarding times of the network access request message; updating the routing channel competition value in the network access request message according to the maximum value between the routing channel competition value and the channel competition estimated value in the received network access request message, and updating the number of competition nodes in the network access request message according to the number of nodes with the routing channel competition value; trying to forward the network access request message to a next-hop node until the next-hop node receives the network access request message and continues to search a destination node, so that the destination node selects a target
