— This paper presents the ALCA (Asymmetric Link Collision Avoidance) protocol. ALCA was designed to deal with a known deficiency of the Basic Scheme [1] for power control in 802...
Network congestion occurs when offered traffic load exceeds available capacity at any point in a network. In wireless sensor networks, congestion causes overall channel quality t...
IEEE 802.11 Distributed Coordination Function (DCF) guarantees fair transmission opportunity to stations. Channel occupation of low rate stations in IEEE 802.11 Wireless Local Area...
—In this paper, we present a model to analyze the performance of three transmission strategies with smart antennas, i.e. directional antennas with adjustable transmission power. ...
Abstract--This paper addresses the fairness of Medium Access Control (MAC) protocols that are capable of handling interference on the physical layer to a varying extent. The variat...
