基于用户简档的比例共享调度及MAC协议
User profile based proportional share scheduling and mac protocol for manets
摘要：
服务质量（Quality of Service，QoS）在移动自组网（Mobile Ad Hoc Networks，MANN）中的重要应用，使得QoS成为一个必须解决的问题。为属于不同配置文件并扮演不同角色的用户提供QoS成为时代的需要。本文提出了一种基于比例共享调度和MAC协议（PS2-MAC）模型。它基于用户的简档将用户分类为高简档用户（HP）、中等简档用户（MP）和低简档用户（LP），并分配比例权重。这三种业务类别的业务区分是通过定量出队算法、可变帧间间隔、成比例的优先级退避定时器和增强的RTS/CTS控制分组来实现的。在ns 2中对区分服务进行了仿真，结果表明，我们提出的方案比现有方案减少了9.5%的控制开销，结果也证明，区分服务已经实现了不同配置文件的用户比例份额，从而减少饥饿。
英文摘要：
Quality of Service(QoS) in Mobile Ad Hoc Networks (MANETs) though a challenge, becomes a necessity because of its applications in critical scenarios. Providing QoS for users belonging to various profiles and playing different roles, becomes the need of the hour. In this paper, we propose proportional share scheduling and MAC protocol (PS2-MAC) model. It classifies users based on their profile as High Profiled users (HP), Medium Profiled users (MP) and Low profiled users (LP) and assigns proportional weights. Service Differentiation for these three service classes is achieved through, rationed dequeuing algorithm, variable inter frame space, proportionate prioritized backoff timers and enhanced RTS/CTS control packets. Differentiated services is simulated in ns2 and results show that 9.5% control overhead is reduced in our proposed scheme than the existing scheme and results also justify that, differentiated services have been achieved for the different profiles of users with proportionate shares and thereby reducing starvation.
