Safe And Efficient Ad Hoc Pathfinding Mechanisms

This thesis 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.First, analysing the current work of the main security mechanisms and routing protocols'strengths and weaknesses and proposing an improved ant colony algorithm to improve the efficiency of the existing route.Second, proposing new route routing rules. For example routing hops, the network energy, bandwidth and energy consumption rate and other parameters.This work effectivly balances the network traffic and extends the network lifetime. Improved Key Agreement Protocol to ensure effective communication session security, and reduce the accompanying increase in security after the new issue of resource consumption.Finally, NS-2 on improving the safety and efficient performance of dual-route mechanism made in terms of experimental results from a comparative analysis of the final results obtained and to analyze its security.
