Abstract

A node in an ad hoc network is accountable for routing the packets to neighboring nodes. This evolves trust factor among nodes on the basis of which packets are forwarded to other nodes if it is trusted and thereby furnishes a secure & reliable communication. This trust can be defined by several approaches which are based on node's behaviour, monitoring, reputation etc. In this paper, an approach is proposed to establish trust among nodes which can be evaluated by monitoring the nodes for their behaviour. The values are defined for trust is dynamic in nature and depends on the behaviour of nodes. Moreover, a table of trust is maintained by all the nodes.
