QoSTRP: A Trusted Clustering Based Routing Protocol for Mobile Ad-Hoc Networks

One of the secured communication methods in MANET is providing a Trust Management (TM). A TM calculates a trust value for all the participants in the communication for security. TM assigns a predefined threshold value for trust variable where it will be checked during communications. If the node has a trust value greater than the threshold value, then the nodes are selected as a most trusted node among the nodes else it is considered as a un-trusted node which cannot be permitted for communication. Various existing research works proposed various Trust Management algorithms and Trusted Routing Protocols. But the efficiency of the existing approaches is not satisfactory up to the market level. This problem takes into account and it is motivated to design and develop a novel QoS improved Trusted Routing Protocol (QoSTRP) for secured efficient data transmission in MANET. The efficiency of the proposed protocol is verified and the performance is evaluated by comparing the results with other existing methods.
