A Novel Cross-layer Quality-of-service Model
Abstract
The divided-layer protocol architecture for Mobile ad hoc Networks(simply MANETs)can only provide partial stack. This leads to treat difficulties in QoS guarantee of multimedia information transmission in MANETs, this paper proposes Across-layers QoS Model for MANETs, CQMM. In CQMM ,a core component was added network status repository(NSR), which was the center of information exchange and share among different protocol layers in the stack. At the same time,CQMM carried out all kinds of unified QoS controls. It is advantageous that CQMM avoids redundancy functions among the different protocol layers in the stack and performs effective QoS controls and overall improvements on the network performances.

1 introduction
With the rapid development of multimedia technologies and the great increase of he bandwidth for personal communication,video and Video services begin to be deployed in MANETs. Different from static networks and Internet,multimedia communications in MANETs such as Voice and Video services require strict QoS guarantee, especially the delay guarantee. In addition, communication among different users can be integrated services with different QoS requirements. These lead to great challenges in QoS guarantee of multimedia communication in MANETs. There are two main reasons in these: 1)MANETs runs in atypical wireless environment with time-varying and unreliable physical link, broadcast channel, and dynamic and limited bandwidth and so forth. Therefore, it can only provide limited capability for differentiated services with strict QoS requirements [1].2) It is difficult that traditional flow project and access control mechanism are implemented because of mobility, multiple hops and self-organization of MANETs.
一种新型的移动AD HOC网络跨层服务质量模型
摘要:分层协议的体系结构只能为移动Ad Hoc网络（简称MANETs ）提供部分堆栈。这给移动Ad Hoc网络中的多媒体通信的质量保证带来了很大的困难。为了改进移动Ad Hoc网络中的多媒体信息传输的服务质量，本文将介绍一种针对移动Ad Hoc网络的跨层服务质量模型—-CQMM。CQMM的一个核心组件是网络状态储存库(NSR)，它是信息交换的中心，而且能在堆栈中的不同协议层之间共享。同时，CQMM能够实现所有标准的QoS 控制。另外，CQMM还能消除堆栈中不同协议层之间的冗余功能，并有效的执行QoS控制和网络性能的全面改善。
关键字: 跨层QoS模型，移动Ad Hoc网络（MANETs） ，网络状态储存库（NSR），QoS控制。
1、 引言随着多媒体技术的快速发展，和个人通信带宽的增加，音频和视频服务已开始在MANETs中出现。与静态网络和因特网不同的是，MANETs中的多媒体通信，如音频和视频服务，它们对QoS的保证有非常严的要求，特别是延迟的保证。此外，具有不同QoS要求用户之间的通信可以集成服务。这给MANETs.多媒体通信的QoS保证提出了很大的挑战。主要有两个原因：1 ）MANETs是在一种传统的无线环境下运行的，即，该环境随时间而变化，具有不可靠的物理链接、广播频道和动态的有限的带宽，等等。因此，它只能为有严格QoS要求的被区分的服务提供有限的能力 [ 1 ]. 2 ）由于MANETs的灵活性，多级跳以及自组性，因而，传 统 的流动项目和访问控制机制就非常难以实现。
