Ad-hoc wireless networks consist of mobile hosts in anetwork without of base stations and characterized by ahighly dynamic network topology. The network topologychanges frequently due to host migration, signalinterference and power outages. This makes routingmaintenance challenging for routing protocol design. Inthis paper, we present an active route maintenanceprotocol to prevent the existing route from disconnecting.By monitoring the status of signal strength and stability ofindividual hosts, an active node that causes the route tohave a weak connection will actively issue a routereestablishing process in which the active host selects oneof its neighbors as the candidate to partially reconstructthe weak connection. An enhanced active routemaintenance protocol is also proposed to reduce theprobability of route breakage and enhance the routeefficiency. Performance simulation results show that theproposed route maintenance protocol effectively reducesboth the overhead and route maintenance, as well asalleviating the route-break phenomenon.
