A Proposal of a Smart Access Point Allocation Algorithm for Scalable Wireless Mesh Networks

Free registration required

Executive Summary

As a flexible, inexpensive, and extensive Internet access network, the authors have studied WIM- NET (Wireless Internet-access Mesh NETwork) composed of multiple Access Points (APs) as wireless mesh routers. WIMNET utilizes two types of APs to achieve the scalability with sufficient bandwidth while reducing costs. One is the expensive, programmable Smart AP (SAP) that can use plural channels for wireless communications and has various functions for the Internet access. Another is the inexpensive, nonprogrammable Conventional AP (CAP) that can use only one channel. To enhance the performance, the proper SAP allocation is critical, because the number of SAPs is much smaller than that of CAPs.
