Medium Access Control (MAC) in Wireless Networks

Medium Access Control (MAC) is a challenging issue in wireless network environments. In cases of increased mobility and a large number of nodes, challenging performance issues are introduced. Analysis of performance is central in this area and the emphasis is on Time Division Multiple Access (TDMA).

Time frame under both topology-independent TDMA MAC policies: Deterministic and Probabilistic. Black colored time slots are used under both policies whereas, grey time slots are used only under the Probabilistic Policy increasing through put in the expense of determinism.
