Dynamic Trust Based Secure Multipath Routing for Mobile Ad-Hoc Networks

Abstract

In this paper, we propose a new secure routing protocol for mobile Ad-hoc networks. The proposed new secure routing protocol works by evaluating the trustworthiness of each node to reduce the hazards from malicious mode and enhance the security of network. A new trust computation model is used to calculate the trustworthiness of a node based on the historical behavior. The trust value is evaluated by including the intruder node using Intrusion Detection System (IDS). In this paper, intruder nodes are detected based on the packet delivery mode during the communication. The Ad-hoc on demand multipath distance vector routing protocol is used in this paper which is based on the trust model that computes the trust of nodes and makes decision accordingly. A new dynamic and trust-based routing protocol named Ad-hoc on demand Dynamic Trusted Multipath Distance Vector (AODTMDV) has been proposed for performing effective and secured multi-path routing in MANETs.
