“…Over the last several years, a lot of research has taken place in this domain, with some quite interesting examples having been published. For example, [5] evaluates QoS in downlink OFDMA wireless cellular networks, [6] presents the challenges and recent advances in QoS provisioning for wireless mesh networks, [7] discusses the provision of QoS guarantees in next generation heterogeneous networks], [8] presents a QoS adaptive framework for WiMax networks and [9] provides a hierarchical QoS framework for wireless multimedia networks. In addition, [10] discusses the subject of QoS in multihop wireless mobile networks, [11] compares centralised and decentralised QoS management policies, whereas [12] presents a game-theoretic analysis of QoS in the wireless medium access control (MAC) layer.…”
