Protecting Transmissions When Using Power Control on 802.11 Ad Hoc Networks

Overview This paper presents the ALCA (Asymmetric Link Collision Avoidance) protocol. ALCA was designed to deal with a known deficiency of the Basic Scheme Gomez et al., 2001 for power control in 802.11 ad hoc networks, which occurs when links become asymmetrical as a result of power control. The proposed ALCA mechanism conveys transmission duration information to these terminals through a simple modification of the 802.11 MAC protocol. Through extensive simulation, the performance of ALCA is investigated and compared to PCM (a solution that requires major hardware updates).
