Abstract

In recent years, many major cities in the world are considering turning
themselves into a vibrant Wi-Fi city, where mobile users may access the
Internet through Wi-Fi connections anytime and anywhere. Due to the
relatively short coverage range of Wi-Fi in indoor environment, in almost
all proposals, the service provider supports only outdoor wireless
broadband access. In order to provide Wi-Fi service with complete coverage,
wireless mesh network (WMN) technology has been actively researched aiming
to improve the citywide Wi-Fi service. Although people are talking about
WMN for several years, however, we have not seen many large-scale real world
deployment of WMN. The main reason is that the implementation usually requires
additional hardware devices and requires proprietary software. In this article,
we present a practical approach for building an efficient wireless mesh network
(Pi-Mesh - A Practical Implementation of Mesh) to extend the Wi-Fi coverage
to indoor environment. Pi-Mesh is a non-proprietary off-the-shelf solutions
for building WMN. To improve its performance, Pi-Mesh runs an access tree
algorithm to improve user throughput by finding quality links dynamically.
Moreover, Pi-Mesh is fully compatible and interoperates with the existing
Wi-Fi access points and devices. These design decisions contribute to ease of
deployment, a very important requirement for large-scale deployment.
