AESCRT: Agent enabled secure CRT based routing topology for MANET

In a MANET, existing techniques for secure routing involves key generation, encryption and decryption logics besides secret sharing. The dynamic nature of MANETs leads to insecurities and inconsistencies in secret sharing. The existing logics for securing the packet delivery seem to involve too many control signal interchanges. This often leads to congestion in the network, thus causing degraded performance. This paper proposes the use of multiple agents to detect secure routes with minimum load on the network. The Chinese remainder theorem is used in generating the secure key by the source node. Source node shares the secure key among all probable routes using multiple agents. These agents reduce control packet overheads and thus reduce congestion in the network. The final route is selected based on the highest weighted trust value of the routes. The three phased approach is aimed to increase the overall performance in the network and also control congestion in the network using agent based approach. Simulation results have been included to justify our claim.
