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

Abstract

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.

Description

technical field [0001] The present invention relates to a communication network, especially a computer network in a wireless self-organizing network, and specifically relates to a hybrid routing mechanism for forwarding packets using network monitoring technology and an address resolution protocol (ARP) proxy mode, which can be used in ordinary wireless In the Ad-Hoc multi-hop self-organizing network composed of network cards. Background technique [0002] The wireless Ad Hoc network is composed of a group of wireless mobile nodes. It is a network system that can be quickly deployed without relying on the existing fixed communication network infrastructure. Self-healing network; each network node cooperates with each other, communicates and exchanges information through wireless links, and realizes the sharing of information and services. Each node of the wireless Ad Hoc network must be both a router and a host, capable of wireless communication by sending and receiving dat...

Problems solved by technology

However, when the farther away node A joins in, because A can only communicate with B at the farthest distance, the other nodes and A are beyond the communication range, and there is no multi-hop routing and forwarding function between nodes, so A Nodes cannot communicate with nodes C, D, E, and F
