| 摘 要： | 无线Ad Hoc网络具有移动性、分布多跳性和自组织等特性,已经被广泛应用于各种无基础架构的环境中.然而,这些特性使得无线Ad Hoc网络的QoS技术面临着众多的挑战.目前Ad Hoc网络中支持QoS的MAC协议可分为同步MAC协议和异步MAC协议,但现有这些协议普遍存在服务区分粒度过粗、无网络饱和控制机制、公平性和分布式时钟同步机制等问题,支持QoS的MAC协议仍需要在服务区分、接纳控制机制、资源的预约和分配机制以及QoS的维护机制方面进行完善.

| Abstract: | Quality-of-Service(QoS) supported in wireless Ad Hoc networks is very difficult because of the inherent characteristics of sharing channel,mobility and distributed multi-hop.The literature on the QoS supported MAC protocols falls in two categories:synchronous and asynchronous protocols.These protocols have the following problems,i.e.,rough granularity of services differentiation,the lack of schemes of network saturation control,fairness and synchronization.The QoS-aware MAC protocol in Ad Hoc networks needs... |
