An improved the DSR routing protocol in mobile ad hoc networks

摘要

In the MANET with high mobility, many routing responses of the contiguous nodes in the DSR routing protocol can not arrive to the resource nodes. So the routing requests which broadcast to these nodes produce much unnecessary use. We can acquire relatively steady routing responses if we chose the contiguous nodes to start the routing require which with less mobility compare with resource nodes. This routing protocol (M-DSR) can improve the efficiency and reduce the use of the limited network resources. The simulation result shows that M-DSR routing protocol has more improvement than DSR routing protocol in terms of route discovery time, routing length, routing error, propagating requests and route replies.
