Local replacement for route recovery on a collaborative mobile ad hoc network
This paper presents an efficient route recovery approach for a collaborative mobile ad hoc network (MANET). In the collaborative MANET, the movement of a node can be controlled by other nodes. Based on the property of the controllable movement, each active node (each node on a route) can be protected by its neighboring nodes. When the movement of an active node causes a link breakage on a route, its neighboring nodes compete with each other to move to the original location of the moving active node. Using the movements of neighboring nodes, the proposed approach can achieve route recovery without pre-establishing or dynamically finding backup routes. The proposed approach also has much less recovery overhead than previous approaches because of the local recovery. Finally, we perform extensive simulations to compare the proposed approach with previous approaches. The simulation results show that the proposed approach has better recovery performance under dense and sparse MANET architectures. Copyright (C) 2010 John Wiley & Sons, Ltd.
