Research On Secure Routing Protocols In Ad Hoc Network

Such convenience and fast to built, and unrestricted by the time and space,Ad hoc networks have got wide and deep application .But due to some of its characteristics such as the absence of infrastructure, frequent changes in network topology, Ad hoc networks can be attacked easily. Consequently, it is more difficult to design security routing protocol for Ad hoc networks.The thesis researched on routing protocol security in Ad hoc networks. First of all, an attempt had been made to compare the performance of four prominent routing protocols (AODV, DSR, DSDV and TORA) for mobile Ad hoc network. By comparing the packet delivery ratio, average end-to-end delay and normalized routing overhead with different node connections for these four routing protocols, the simulation method and results were presented; the dynamic effect can be seen by the "nam". Then, analyzed several typical security routing protocols in Ad hoc networks. On the basis of comprehensive analysis in the routing attack carried out the insufficiency. Finally, in view of the insufficiency, we brought forward a new thought.
