A MobileLAN can provide group mobile users the ubiquitous information access capability. In a wireless communications environment, the performance will be affected by various factors such as signal strength, route length, system load, etc. Such a system must manage its topology carefully in order to maintain the quality of service. Routing in a MobileLAN is actually to select a sub-topology from the original network topology and let all the communications follow the paths defined by the selected sub-topology. Current routing algorithms are mostly concerned with the path length, i.e. the number of hops, between the source nodes and the destination nodes. The signal strength and the system load are all ignored. In this study, we proposed a The Ad Hoc Backup Node Setup Routing Protocol (ABRP) and The Ad Hoc Multicast Backup Node Setup Routing Protocol (AMBRP) routing algorithms to focus attention on the intrinsic properties of the ad hoc wireless networks. It more completely considers the quality of routing than the routing protocols proposed in the past. According to the proposed ABRP and AMBRP, many routes can be found to reach a destination in a given period. Those routes, almost more than one, from the source node to the destination node can be analyzed to obtain some good backup routes or multicast backup routes to support reconnection when a link fails. The backup route information can be saved in a specific on-the-route node. These backup routes can be rapidly found in situations involving disconnection or loss of connection. Furthermore, ABRP and AMBRP provides the backup node and the multicast backup node mechanism that reconnects quickly as required for ad hoc wireless networks. In this study can overcome the mentioned above shortcoming. The simulation results show that ABRP and AMBRP approach may reduce the average packet transmission time as well as avoid potential hot-spot effect. Chi Ming Chung 莊淇銘 2004 學位論文 ; thesis 94 en_US |
