Abstract

The invention discloses an Ad Hoc network on-demand routing protocol establishing and maintaining method based on path collecting. The Ad Hoc network on-demand routing protocol establishing and maintaining method based on route collecting includes the following steps that multiple paths based on the link non-intersect multiple path algorithm are established, a sequential node ID of a whole path in each path is recorded, a loop-free mechanism using a downlink node to transmit an identification achieves the fact that a route is free of loops. When selection is made among multiple paths, the most-recently established path is selected in priority. Only the used path is maintained. The Ad Hoc network on-demand routing protocol establishing and maintaining method based on routine collecting can improve the routine discovery efficiency, reduce routine expenditure, improve stability of the communication paths, relieve influences of breakage of the communication paths and improve the capability of obtaining routine information, wherein the breakage of the communication paths is caused by node movement.

Description

technical field

[0001] The invention relates to a network routing protocol, in particular to a method for establishing and maintaining an Ad Hoc network on-demand routing protocol based on path collection. Background technique

[0002] The Ad Hoc network is composed of many communication terminals with wireless transceiver devices. It does not require existing infrastructure and can be dynamically reconfigured. It has the advantages of quick establishment, flexibility, and strong indestructibility. It is suitable for battlefields, disaster relief, and environmental protection Monitoring and other fields have broad prospects for development. However, while the Ad Hoc network has the above advantages, the characteristics of high dynamics, limited energy, and low wireless bandwidth also pose a huge challenge to the design of Ad Hoc routing protocols. On-demand routing protocols in Ad Hoc networks have the problems of "broadcast storm" and communication path interruption ca...
