Mobility Aware Trust Assessment Multipath Routing (Matar) For Mobile Adhoc Networks
A Mobile Adhoc Network (MANET) is an autonomous infrastructureless network that is self-organized by mobile nodes communicating with each other dynamically and freely. In such kind of environments, security provision is a challenging task. Due to the mobility, the mobile nodes moves out and in of radio frequency range which results in the link breakages followed by packet drops. For a packet drop, confusion will arise whether it was happened due to mobility or due to compromised node and results is more number of false positives and less Quality of Service. To overcome these problems, in this paper, a new routing mechanism called as Mobility Aware Trust Assessment Routing (MATAR) is proposed. In MATAR, each node measured its neighbor node’s trustworthiness with respect to its packet forwarding history. Both direct and recommended trusts are evaluated here and also linked the total trust with the mobility of respective node. In this approach, the route trust is computed by the integration of individual intermediate node’s trustworthiness. Further, a trust application is defined with respect to five node classes which helps in the provision of an alternative nodes and results in the QoS preservation. An extensive Simulation experiments are performed over the proposed model and the performance is measured through Malicious Detection Rate, Throughput and Routing Overhead. The results show that the MATAR improves the Quality of Service along with accurate detection of malicious nodes.
