Using a Directional Antenna to Achieve Quality Transmission on a Wireless Ad Hoc Network Under Jamming Attacks

Wireless ad hoc networks are constructed in such a way that the total available bandwidth is shared among all the transmitting nodes at any given time. Consequently, it is very easy for adversaries to launch jamming attacks. Jamming attacks target the network service availability by either blocking communication links between network devices or by blocking a single device from sending data hence making the instance of communication useless. In this survey, the authors model a project using OPNET Modeler 10.5 in which they demonstrate the negative effects of jamming signals on the quality of transmission between two wireless stationary ad hoc nodes, which are communicating using only Omni-directional antennas.
