Secure routing protocol in MANET using TAC

MANET is the self-organized and distributed system with no central administration and requires no infrastructure. Due to this, the MANET is used in emergency services and during natural calamities. Nodes have to co-operate with each other for routing packets. Security is the major challenge for these networks. The compromised node can adversely affect the quality and reliability of data. To improve the security of the MANET, it is essential to evaluate the trustworthiness of nodes. In this paper, we have used the scheme that evaluates the trusted communication path with the help of Trust Allocation Certificate TAC. TAC declares the degree of trustworthiness of particular node. TAC can be used to detect the spoofed ID, trust falsified and packet dropping behavior of nodes.
