Route recovery based on anycast policy in mobile ad hoc networks

Mobile ad hoc network (MANET) is a special wireless network, which is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of pre-established network infrastructure. Because of its dynamic topology and mobility, the path for transmitting the date is easy failure in MANET. For the real-time transmission, route must be rebuilt rapidly after route failing. In the paper, we mainly discuss the route recovery problem and propose an efficient route recovery method based on anycast policy. By using the method, the route could be found rapidly after the transmitting route fails. But possibly the recovery route is not the best path for transmitting data. The simulation results show that the protocol gets lower average route recovery delay than others.
