  • 摘要:In this paper, we have taken out the concern of security on a Medium Access Control layer implementing Assured Neighbor based Security Protocol to provide the authentication, confidentiality and taking in consideration High speed transmission by providing security in parallel manner in both Routing and Link Layer of Mobile Ad hoc Networks. We basically divide the protocol into two different segments as the first portion concentrates, based on Routing layer information; we implement the scheme for the detection and isolation of the malicious nodes. The trust counter for each node is maintained which actively increased and decreased considering the trust value for the packet forwarding. The threshold level is defined differencing the malicious and non malicious nodes. If the value of the node in trust counter lacks below the threshold value then the node is considered as malicious. The second part focus on providing the security in the link layer, the security is provided using CTR (Counter) approach for authentication and encryption. Hence simulating the results in NS-2, we come to conclude that the proposed protocol can attain high packet delivery over various intruders while attaining low delays and overheads.
