CCMP-AES Model with DSR routing protocol to secure Link layer and Network layer in Mobile Adhoc Networks
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 5
Abstract
Mobile Adhoc network is a special kind of wireless networks. It is a collection of mobile nodes without having aid of stablished infrastructure. Mobile Adhoc network are vulnerable to attacks compared to wired networks due to limited physical security, volatile network topologies, power-constrained operations, intrinsic requirement of mutual trust among all nodes. During deployment, security emerges as a central requirement due to many attacks that affects the performance of the ad hoc etworks. Particularly Black hole attack is one such severe attack against ad hoc routing protocols which is a challenging one to defend against. The proposed model combines the On demand routing protocol DSR with CCMP-AES mode to defend against black hole attack and it also provides confidentiality and authentication of packets in both routing and link layers of MANET. The primary focus of this work is to provide security mechanisms while transmitting data frames in a node to node manner. The security protocol CCMP-AES working in data link layer keeps data frame from eavesdropping, interception, alteration, or dropping from unauthorized party along the route from the source to the destination. The simulation is done for different number of mobile nodes using network simulator qualnet 5.0. The proposed model has shown better results in terms of Total bytes received, packet delivery ratio, throughput, End to End delay and Average jitter.
