[书籍] Distributed Medium Access Control in Wireless Networks (SpringerBriefs in Computer Science)
出版社:
Springer
简介:
This brief investigates distributed medium access control (MAC) with QoS provisioning for both single- and multi-hop wireless networks including wireless local area networks (WLANs),wireless ad hoc networks,and wireless mesh networks. For WLANs,an efficient MAC scheme and a call admission control algorithm are presented to provide guaranteed QoS for voice traffic and,at the same time,increase the voice capacity significantly compared with the current WLAN standard.In addition,a novel token-based scheduling scheme is proposed to provide great flexibility and facility to the network service provider for service class management. Also proposed is a novel busy-tone based distributed MAC scheme for wireless ad hoc networks and a collision-free MAC scheme for wireless mesh networks,respectively,taking the different network characteristics into consideration.The proposed schemes enhance the QoS provisioning capability to real-time traffic and,at the same time,significantly improve the system throughput and fairness performance for data traffic,as compared with the most popular IEEE 802.11 MAC scheme.
