多代理系统在异构无线网络资源管理中的应用

在网络向着高速化、宽带化、泛在化发展的过程中,出现了多种多样的无线通信系统,给网络带来了丰富的异构性。然而异构网络缺少互通机制,缺乏有效的协调,具有系统间的干扰、单一网络业务提供能力有限、频谱资源稀缺等问题,网络资源利用率低下。为使网络资源能够高效使用,联合资源管理必不可少。而传统的集中式资源管理架构不能满足异构网络环境的需求,分布式基于多代理的网络资源管理架构将是未来异构无线网络联合资源管理的主要形式。

The Application of Multi-Agent System for Resource Management in Heterogeneous Wireless Networks

With the development towards high speed, wideband and ubiquity, various wireless access technologies are emerging, which brings heterogeneity to wireless communications systems. However, heterogeneous networks lack interactive mechanisms and effective co-ordination, and have many problems such as the inter-system interference, limited service providing capability and spectrum resource scarcity, which result in the low network resource utilization. To take full advantage of network resources, joint resource management is absolutely necessary. Whereas, under heterogeneous network environment, traditional central resource management architecture can not satisfy the requirements, distributed multi-agent based network resource management architecture will be the main mechanism in the future for joint resource management.
