【摘要】 随着通信技术的发展,移动自组网络得到了越来越广泛的应用,网络也在朝着大规模的方向发展。如何设计出一种高性能的分层路由协议是一个具有挑战性的任务,本文介绍了Ad Hoc网络中现有的路由协议,并针对分层Ad Hoc网络的特点提出了一种基于网络编码理论的路由方法CLGSR(Coding cLusterhead Gateway Switch Routing)。该方法将网络编码理论引入路由协议的设计,以提高网络性能。由于群内和群间的网络拓扑特点不同,结合不同的网络编码技术提出不同的群内和群间路由算法,群内路由算法通过监听发现在广播过程中的编码机会,而群间路由算法在路由发现过程中可以主动的发现编码机会,将其带入到路由抉择过程中。在OPNET10.5软件平台上对CLGSR协议进行了仿真,将储存转发方式和两种编码方式进行了对比。仿真结果表明,在吞吐量和时延等网络性能方面CLGSR要优于其余的方法。更多还原

【Abstract】 With the development of the communication technology, the application of Mobile Self-organized Network is becoming more and more widely. At the same time, the network is developed to the large scale. How to design a well hierarchical Routing Protocol is a challenging task. In this paper, the existing Routing Protocols for Ad Hoc Network are introduced. Then, considering the layered characteristics of Ad Hoc Networks, we proposed a Coding cLusterhead Gateway Switch Routing protocol, in which network coding theory is applied to improve network performance. As the difference in network topology between the Intra-cluster and Between-cluster,The intra-cluster routing algorithm found the opportunity to coding by listening in the process of broadcasting. The between-cluster routing algorithm can take the initiative to find opportunities for code in the routing discovery process. Simulations of the proposed routing protocols are completed by OPNET Modeler. Results show that the proposed CLGSR is superior to the traditional algorithms, and network coding explicitly improve the performance of network.更多还原
