Dear all ns users, For the following topology i am using DSR and AODV routing protocols. I define two ftp traffic from node 0 to node 3 and node 1 to node 3. When i use DSR, there is no problem, packets are flowing in the routes 0->2->3 and 1->2->3. But when i use AODV, traffic cannot be started because node 3 (sink node) is not in the communication range of node 0 or node 1, AODV cannot find a route to node 3. When i close the node 3 to node 0 and node 1 (that is into the communication range), traffic is flowing in the route 0->3 and 1->3. It seems AODV cannot define a route with intermediate route. The aim of a routing protocol should be to find a route to destination. But I don't understand why such a situation occurs. If you know the problem for such a situation, please help me. Many thanks in advance. Semra
