Pervasive Internet via Wireless Infrastructure-Based Mesh Networks
Abstract
With the arrival of Wi-Fi, WiMax, Zigbee, and other wireless network standards, the penetration of Internet in daily life has surged significantly. While the usage of Internet access in urban areas is steadily increasing in recent years, rural people are still suffering from the effect of the digital divide, mainly due to the poor coverage by Internet service providers in remote areas. This chapter aims to provide a cost-effective reliable broadband Internet access solution for rural people in the form of Wireless Mesh Network (WMN) whose coverage can be easily extended in a multi-hop fashion. Starting from a general description of the WMN architecture and protocol developments, this chapter focuses on the primary design issues and challenges for making Internet pervasive through WMN’s that demand innovations in protocols at different layers and perfect integration. The brief discussion on the research works and related experimental testbeds shows that WMN with its unique features seems to be a promising solution to provide next generation Internet access to areas that are too remote to receive it via cable or DSL, or where upgrading the landlines to broadband is highly cost-prohibitive. Finally, this chapter concludes introducing various open issues and research challenges still to be addressed and resolved in coming days to make this solution commercially viable.
