Abstract

The invention discloses a route building method. It includes the following steps: judging whether source node has destination node route or not; if it is, the route is effective which can be confirmed by middle node energy and the data packet traffic capacity and sending data packet by it; if it is not, broadcasting the RPEQ carried with traffic capacity; judging whether the received RPEQ node is the destination node or not; if it is, returning the route from the source node to destination node and the PREP to the source node and transmitting the data packet according to the route; if it is not, confirming the middle node is effective and searching the effective route. Thus the invention can increase route building efficiency.

Description

technical field

[0001] The invention relates to routing technology, in particular to a routing establishment method in a wireless network with nodes having routing functions. Background technique

[0002] Based on people's strong desire to get rid of the shackles of wired networks and communicate freely anytime and anywhere, wireless network communications have developed rapidly in recent years. In order to carry out wireless communication in places without fixed wired infrastructure, wireless ad hoc network (Ad hoc) technology emerges as the times require. In this network, a group of mobile nodes with wireless transceivers form a base station, multi-hop, temporary autonomous network, and each mobile node has a router function, which can perform sending and receiving during data communication. And the function of forwarding data packets.

[0003] Since the Ad hoc network does not need fixed wired infrastructure support, compared with the traditional communication network, ...
