TLDR
A novel secure routing protocol for MANETs that extends the widely used AODV (ad hoc on-demand distance vector) routing protocol and employs the idea of a trust model to protect routing behaviors in the network layer of MANets.Abstract:
Security issues have been emphasized when mobile ad hoc networks (MANETs) are employed into military and aerospace fields. We design a novel secure routing protocol for MANETs. This protocol TAODV (Trusted AODV) extends the widely used AODV (ad hoc on-demand distance vector) routing protocol and employs the idea of a trust model to protect routing behaviors in the network layer of MANETs. In the TAODV, trust among nodes is represented by opinion, which is an item derived from subjective logic. The opinions are dynamic and updated frequently as our protocol specification: if one node performs normal communications, its opinion from other nodes' points of view can be increased; otherwise, if one node performs some malicious behaviors, it is ultimately denied by the whole network. A trust recommendation mechanism is also designed to exchange trust information among nodes. The salient feature of TAODV is that, using trust relationships among nodes, there is no need for a node to request and verify certificates all the time. This greatly reduces the computation overheads. Meanwhile, with neighbors' trust recommendations, a node can make objective judgement about another node's trustworthiness to maintain the whole system at a certain security level.read more

Ad-hoc on-demand distance vector routing
C.E. Perkins,E.M. Royer +1 more
TL;DR: An ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure and the proposed routing algorithm is quite suitable for a dynamic self starting network, as required by users wishing to utilize ad- hoc networks.
Dynamic Source Routing in Ad Hoc Wireless Networks.
David B. Johnson,David A. Maltz +1 more
TL;DR: In this article, the authors present a protocol for routing in ad hoc networks that uses dynamic source routing, which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently.

Highly dynamic Destination-Sequenced Distance-Vector routing (DSDV) for mobile computers
TL;DR: The modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile hosts.

Mitigating routing misbehavior in mobile ad hoc networks
TL;DR: Two techniques that improve throughput in an ad hoc network in the presence of nodes that agree to forward packets but fail to do so are described, using a watchdog that identifies misbehaving nodes and a pathrater that helps routing protocols avoid these nodes.
