Radio Resource Sharing Model for Coexisting IEEE 802.11e Wireless LANs

摘要

A game model is developed and evaluated to analyze the Quality of Service (QoS) support in IEEE 802.11e Wireless Local Area Networks (WLANs) that share radio resources in a coexistence scenario. In such scenarios, QoS cannot be supported by the 802.11e Medium Access Control (MAC) protocol because of the unsolved competition between WLANs that operate in an unlicensed spectrum. A stage-based game model is introduced here in which WLANs are modeled as players. A player represents a Quality of Service Basic Service Set (QBSS). The interaction of the players within the Single Stage Game (SSG) is analytically modeled and evaluated with simulation.
