Forwarding method used for constructing multi-hop routing in wireless self-organizing network

The invention provides a forwarding method used for constructing multi-hop routing in a wireless self-organizing network, which is based on an ARP proxy system and a mixed routing system. The method comprises the following steps that: a monitoring module of each node monitors each message sent and received by the node in real time; adjacent hosts interact respective routing information in a single-hop range in real time; each node stores a partial or complete topology table of the whole network; when a certain node of the network sends an ARP request to a node which is not directly connected with the certain node, the certain node searches for a next-hop node and sends a routing detection message to the next-hop node according to a routing list; and if the route is reachable, the detection message is transmitted to a target node step by step and returns a routing reachable message, and ARP proxy tables are arranged at various nodes along the route, so a multi-hop route is established. The invention also comprises a method for maintaining and updating the route through modification of network topology detection. The invention also comprises a device used in the network, and describes a complete communication system shown in graph 1.
