Abstract
The characteristics of self-organization, wireless medium, and the absence of fixed infrastructure make Mobile Ad hoc NETwork (MANET) easy to set up, and thus attractive to users. However, the open and dynamic operational environment of MANET makes it very vulnerable to attacks such as denial of service attacks, radio–jamming attacks, impersonation attacks and fabrication attacks. Another common type of attacks at MANET targets at the underlying routing protocols. Because every network node in a MANET can be a router for data transmission, malicious nodes have opportunities to modify or discard routing information or even to advertise fake routes in an attempt to attract user data to go through themselves.
Some new routing protocols have been proposed to address the issue of securing routing information. However, a secure routing protocol cannot single-handedly guarantee the secure operation of the network in every situation. The objectives of the thesis are two-fold: (a) To simulate various scenarios of attacks at MANET; (b) To study the performance and effectiveness of some secure routing protocols, including the Secure Ad-hoc On demand Distance Vector routing protocol (SAODV) [8] and ARIADNE [6], in these simulated malicious scenarios. If time permits, I would like to propose an optimal security solution to improve the
