Secure Trust Management with Source Routing Protocol for MANETs

Abstract

A MANET, in order to work properly, needs its nodes to work collaboratively. This is not always the case, and thus tools are developed to detect and identify uncooperative nodes. In this paper we present TADSR, a protocol based on an already existing secure routing protocol on top of which it adds trust management features. Our aim is to detect rogue nodes, and also to improve the overall performance of the original protocol. The information gathering process will encompass both direct means and an indirect process through which other nodes will provide their own assessments. Then, a punishments and prizes system will try to get involved as many nodes as possible to improve the network performance.
