Ad hoc on-demand backup node setup routing protocol

An ad hoc wireless network provides infrastructureless data networking, where users have network services while they are continually moving. Instructureless, and mobility are properties of the ad hoc wireless networks. Furthermore, each move of the mobile host affects the change of network topology, and affects the change of the transmission route. There are numerous routing protocols developed for ad hoc wireless networks, and they may be generally categorized as table-driven or source-initiated on-demand. However, the properties of the ad hoc wireless networks still affect those routing algorithms. The ad hoc backup node setup routing protocol (ABRP) is proposed to lead us pay move attention on the intrinsic properties of the ad hoc wireless networks. It provides a more complete consideration of the routing quality. According to the proposed ABRP, the destination can receive some more routes in a period of time. Those routes from the source node to the destination node may give us ways to analyze and find some good backup routes to get more help for reconnection when a link failure occurs. The backup route information can be saved in a specific on-the-route node. The enables the backup routes to be rapidly found and traced back to these nodes when there are situations such as disconnection or connection loss. Moreover, the ABRP provides a backup node mechanism to reconnect maintenance quickly, so meeting the property of ad hoc wireless networks
