本文提出了一种联合物理MAC层的设计框架，估计以及提高无线局域网的容量。该框架基于无线电传播建模的集成（即，物理层）和第二层网络协议（即，MAC层）。其概念是收集无线信道条件的信息，并与MAC协议共享这些信息，以便网络即使在恶劣的干扰环境中也能有效地运行。所提出的框架是简单的，易于实现，并可用于需要大规模的无线网络，如校园范围内的无线局域网的应用。本文描述了跨层设计框架，并给出了实现该框架的两种算法。
This paper proposes a joint physical-MAC layer design framework for estimating as well as improving the capacity of wireless LANs. The framework is based on the integration of radio propagation modeling(i.e., the physical layer) and the layer-2 network protocol (i.e., the MAC layer). The concept is to gather information of wireless channel conditions and share this knowledge with the MAC protocol, so that the network can operate efficiently even in the harsh interfering environments. The proposed framework is simple and easy to implement, and can be used for applications requiring large-scale wireless networks such as a campus-wide wireless LAN. In this paper the cross-layer design framework is described and two algorithms for the implementation of the framework are presented.
