Route switching is an important issue to connection-oriented communication that needs to maintain a route for a certain period. This paper suggests a new approach to ease the route switching problems in a network with higher migration rate of hosts. By monitoring the signal strength of messages, a host in a route that receives an incoming message can detect possible route fluctuations locally. As the average signal strength declines into a dangerous level, the host that receives the message will send an advance-warning message to the route source host. If the source host can find more stable routes locally, it will adapt a substitute route and will complete the process of adaptation before the breakdown of the original route actually occurs. If the route source host cannot adapt a new route locally, the source host will be forced to search for a new route by considering the entire network.
