作为一个灵活的，成本效益高的解决方案，可扩展的互联网接入网络，我们已经研究了无线互联网接入网状网（WIMNET）的体系结构和设计优化问题，它是由无线连接的多个接入点（AP）。WIMNET利用两种类型的AP作为无线网状路由器，以实现足够带宽的可扩展性，同时降低成本。一种是昂贵的可编程智能AP（SAP），它可以使用多个信道进行无线通信，并具有各种互联网接入功能。另一种是一种廉价的、不可编程的传统AP（CAP），它只能使用一个信道。为了提高WIMNET的性能与少量的昂贵的SAP，SAP在网络领域的分配是非常重要的。在本文中，我们提出了一个SAP选择算法选择一个固定数量的SAP从一组给定的分配AP。然后，我们将该算法扩展到寻找最小SAP集，提供最大的吞吐量的有效WIMNET。我们验证了我们的建议，通过广泛的模拟使用WIMNET模拟器的有效性。
As a flexible, cost-efficient solution for a scalable Internet-access network, we have studied the architecture and design optimization issues of theWireless Internet-access Mesh NETwork (WIMNET) that is composed of wirelessly connected multiple access-points (APs). WIMNET utilizes two types of APs as wireless mesh routers to achieve the scalability with sufficient bandwidth while reducing costs. One is an expensive, programmable smart AP (SAP) that can use plural channels for wireless communications and has various functions for the Internet access. Another is an inexpensive, non-programmable conventional AP (CAP) that can use only one channel. To enhance the performance of WIMNET with a small number of costly SAPs, the allocation of SAPs in the network field is very important. In this paper, we propose a SAP selection algorithm of selecting a fixed number of SAPs from a given set of allocated APs. Then, we extend this algorithm to finding the minimal SAP setthat provides the maximal throughput for the efficient WIMNET. We verify the effectiveness of our proposals through extensive simulations using the WIMNET simulator.
