ABSTRACT

In MANET(Mobile Ad-Hoc Network), providing security to routing has been a significant issue recently. Existing studies, however, focused on either of secure routing or packet itself where malicious operations occur. In this paper, we propose SRPPnT(A Secure Routing Protocol in MANET based on Malicious Pattern of Node and Trust Level) that consider both malicious behavior on packet and secure routing. SRPPnT is identify the node where malicious activities occur for a specific time to compose trust levels for each node, and then to set up a routing path according to the trust level obtained. Therefore, SRPPnT is able to make efficient countermeasures against malicious operations. SRPPnT is based on AODV(Ad-Hoc On-Demand Distance Vector Routing). The proposed SRPPnT, from results of the NS-2 network simulation, shows a more prompt and accurate finding of malicious nodes than previous protocols did, under the condition of decreased load of networks and route more securely.
