Abstract�� In a mobile Ad Hoc network, routing salvage is used to decrease routing overhead and ensure high delivery rate. The ratio of cached routes between the intermediate node and the determination to the total routes in the network was used to estimate the probability of the routing salvage from the breakage. Based on the routing salvage the formula for the routing overhead was advanced with time to live(TTL), and TTL is to eliminate the impact of expired routes. The optimal TTL was used to minimize the routing overhead. The simulation demonstrates: ��the formula for the probability of routing salvage is accurate compared with the simulation; ��routing salvage and TTL can cut down routing overhead and improve the delivery rate nearly 20%.
