Abstract

—We discuss a few problems introduced by the
RTS/CTS mechanism of collision avoidance and focus on the
virtual jamming problem, which allows a malicious node to
effectively jam a large fragment of a wireless network at a
minimum expense of power. We propose a solution to this
problem and provide experimental data illustrating the impact of
virtual jamming and the effectiveness of our proposed solution.
