Wireless mobile ad-hoc networks are those networks which has no physical links between the nodes. Due to the mobility of nodes, interference, multipath propagation and path loss there is no fixed topology in this network. Hence, some routing protocol is needed to function properly for these networks. Many Routing protocols have been proposed and developed for accomplishing this task. The intent of this paper is to study three ad-hoc routing protocols ZRP, DSR and STAR in the presence of some misbehaving nodes and analyze them. This paper concentrates evaluating the performance of routing protocols when some nodes behave as malicious ones. The performance analysis for above protocol is based on variation in speed of nodes in a network with 50 nodes.
