For Ad Hoc Network Security Routing Protocol

With the applications of Ad hoc network, the main problems existing are the issues of security and resources consumption. How to ensure safety in the routing processes, to save limited resources and communication bandwidth are the main issues to be resolved.This paper has done the following work to improve the overall efficiency of routing, lengthen life cycle of the network and reduce overall cost of the network system when considering the security of the routing of the Ad hoc network and the increased cost of the system after improving the security of the routing.Firstly, introduce all the aspects of the Ad hoc networks and the Multicast network in brief. Particularly introduce the basic objectives of the Ad hoc network routing security, the current Ad hoc network routing protocols, multicast routing protocols and the security threats encountered by the routing protocols. Also the common mechanisms to protect the safety of the Ad hoc networks and multicast routing are described at current. In addition, the strengths and weaknesses of the work mechanisms of the main security routing protocols are analyzed.Secondly, the routing protocols are designed and improved, the routing mechanisms are proposed and the double routing rules are improved. The selection of routing information references many parameters such as routing hops, the network energy, bandwidth, energy consumption and so on. This kind of selection brings the effective balance of network traffic and extends the network lifetime. Improved Key Agreement Protocol effectively ensures the security of communication and reduces the new issues of resource consumption problems with the improvement of the security.Thirdly, the adaptive multicast routing protocols are designed and proposed to meet characteristics of Ad hoc network which are low overhead and high network performance. According to the mobility of neighbor nodes, changing situations and speeds are determined in multicast of Ad hoc. The appropriate multicast protocol which considers the strengths and weaknesses of the multicast tree and multicast network is adopted to improve the multicast routing protocols.Finally, the simulation and testing of the proposed security routing protocols and the improved multicast routing protocols are made. The comparison and analysis of experiment results are also made after the verification of the safety. Also the future research prospects are proposed.
