ABSTRACT: Evaluation of
IEEE 802.11 Mobile Ad Hoc Networks (MANET) security issues becomes significant
concern for researchers since Denial of Service (DoS) attacks are recognized as
one of the most harmful threats. A variety of security mechanisms are proposed
to solve security dilemma in MANETs against different layers of DoS attacks.
Physical Layer jamming attacks exhaust the victim’s network resources such as
bandwidth, computing power, battery, etc. Unified Security Mechanism (USM) and
Rate Adaptation Scheme (RAS) are two of the proposed methods by researchers
against DoS attacks. USM and RAS mechanisms are simulated through OPNET
simulator and Jamming Attack is generated on the network for each security
mechanisms to compare specific performance metrics on the network.
