Evaluations of secure MANET routing protocols in malicious environments.

摘要

The characteristics of self-organization and wireless medium make Mobile Ad hoc NETwork (MANET) easy to set up and thus attractive to users. The open and dynamic operational environment of MANET makes it vulnerable to various network attacks. A common type of attacks targets at the underlying routing protocols. Malicious nodes have opportunities to modify or discard routing information or advertise fake routes 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 in these simulated malicious scenarios, including ARIADNE [1] and the Secure Ad hoc On-demand Distance Vector routing protocol (SAODV) [2].
