On-demand ad hoc routing protocol with backup node

An ad hoc wireless network provides infrastructureless and mobility data networking, each move of the mobile host affects the change of network topology and the route of transmission. The ad hoc backup node setup routing protocol (ABRP) provides more complete consideration of the routing quality. In ABRP, the destination can receive more routes in a given period of time. Those routes from the source node to the destination node may give us ways to analyze and find some backup routes to get more help for reconnection when a link failure happens. The backup route information can be saved in a specific on-the-route node. The backup routes can be rapidly discovered and one can trace back these nodes when there would be situations such as disconnections. Moreover, ABRP provides a backup node mechanism to reconnect maintenance quickly for fitting the property of the ad hoc wireless networks.
