混合网络研究

Research on Hybrid Network

自组织网和蜂窝网是移动通信系统的重要组成部分,融合两者的混合网络将可能成为未来移动通信系统的重要组成形式之一。文章介绍了混合网络的研究现状,分析了各网络模型的特性,并对混合网络中的关键技术问题,如框架结构、通信模式选择、信道分配、路由、计费、负载均衡,进行了探讨。文章认为混合网络通过其灵活的网络组建能力,不仅提高了对传统业务的支持,同时也为引入新服务创造了条件。自组织网络和蜂窝网络的融合将为构造下一代移动通信系统奠定基础。

The Ad hoc network and cellular network are two main components of the wireless communication system. A hybrid wireless network formed by them may be an important pattern of the next-generation mobile communication system. The paper introduces the status quo of the study of hybrid networks, and analyzes characteristics of various hybrid network models. Moreover, it discusses some key technical issues for hybrid networks, including architecture, communication mode selection, channel distribution, routing, billing and load balancing. The paper concludes that the hybrid networks, with their flexible architecture, not only enhance the support for traditional services, but also create conditions for introducing new services. It thinks that convergence of Ad hoc network and cellular network is the basis of the next-generation mobile communication system.
