Trust-based Approachesto Solve Routing Issues in Ad-hoc Wireless Networks: A Survey
ABSTRACT Trust is important in Ad-hoc networks because collaboration and cooperation among nodes are critical towards achieving the system's goals, such as routing reliability. In this paper, we seek to provide an understanding of the process of reputation-based trust approaches and related issues as they apply to routing in ad-hoc networks. We discuss the concept and properties of trust. We survey the following issues: the way wireless ad-hoc nodes first assume trust; the evidences that are collected to calculate trust; the calculations that are performed over the evidences; the way the decision is made to determine a trusted node; and how trust is updated to maintain a trusted environment. We provide a comparison of three well-established approaches and discuss some potential attacks against reputation-based trust.
Conference Paper: Administrator and Trust Based Secure Routing in MANET[Show abstract] [Hide abstract]
ABSTRACT: The advent of mobile ad hoc (MANET) network had spurred in a new era of communication where users (nodes) communicate with each other via a self configuring infrastructure less network of mobile devices connected by wireless links. Nodes can participate both as a host as well as a router willing to forward packets for other nodes. So here arises the need of a routing protocol. Now the dynamic topology of the network owing to the node mobility becomes the most challenging part of a routing protocol as it demands a protocol which quickly adapts to topology changes with minimizing control traffic such as periodic update message because of limited resource like storage capacity, battery power and bandwidth. In this paper, we have proposed a new routing scheme, Administrator and Trust Based Secure Routing in MANET (ATSR) which provides routing by making an important use of a parameter, trust, an integer value, helping in the selection of administrator inside the network for routing. The message confidentiality and integrity has also being implemented. The simulation result shows the efficiency, lustiness and trustworthiness of our proposed routing scheme.Advances in Mobile Network, Communication and its Applications (MNCAPPS), 2012 International Conference on; 01/2012
Conference Paper: Secure Multipoint Relay based Routing in MANET[Show abstract] [Hide abstract]
ABSTRACT: Security in routing is a challenging issue in mobile ad-hoc (MANET) network because of its open nature, infrastructure less property, mobility and energy constraints. Messages typically roam in multi-hopped fashion and nodes may be powered by limited energy source and with limited physical security. So we proposed a new scheme which is significantly different from others available schemes to provide security during routing in mobile ad hoc networks. In this paper, our proposed scheme, Secure Multipoint Relay based Routing in MANET (SMRR) provides routing based on trust, which is an integer value that helps to select Multipoint Relay (administrator) inside the network for routing. We have also implemented the message confidentiality and integrity in our proposed scheme. Our simulation results show the robustness, reliability and trustworthiness of our scheme.Proceedings of the Second International Conference on Computational Science, Engineering and Information Technology; 10/2012
