【摘要】 阐述了无线Mesh网络(WMN)的基本原理,并将其同移动AdHoc网络(MANET)和无线AdHoc传感器网络(WASN)进行简单比较,然后集中分析了WMN的3大优点:高性能、可扩展和低成本。重点讨论设计和构造高性能和可扩展的无线骨干网络面临的3大具有挑战性的技术难题以及可能的解决途径。此3大难题是:如何设计容量高、传输可靠的无线Mesh骨干网络;如何构造高扩展性的联网功能;如何实现系统水平资源管理,为每个用户提供平等接入Internet机会。最后论述了WMN必将在未来宽带无线接入系统中取得广泛应用。更多还原

【Abstract】 First,the basic principle of wireless mesh networks is briefly described and compared with MANET and WASN.We concentrate on discussing three important advantages of WMN as follows: reduction of installation costs,reliability,and self-management.At the same time,the construction of scalable and high-capacity WMN faces three challenging problems as follows: how to design high-capacity and reliable radio interface for wireless backbone;how to provide scalable networking function;how to realize system-level resource management with fair share of system resource for each user.Finally,WMN is shown to have an extensive range of applications in future wireless wideband access system.更多还原
