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.

As an inexpensive, flexible, and scalable Internet-access wireless network, we have studied the architecture, protocols, and design optimizations of the Wireless Internet-access Mesh NETwork (WIMNET) that adopts multiple access-points (APs) connected through wireless links. WIMNET can improve the dependability to failures of APs and/or their links by allocating APs redundantly in the network field. Because redundant APs may increase the operational cost and degrade the throughput due to increasing radio interferences, only the necessary APs for connectivity between the hosts and the Internet gateway should be activated in communications. In this paper, we first define the active AP selection problem of selecting the minimum number of active APs, and prove the NP-completeness of its decision version through reduction from the known minimum set cover problem. Then, we propose an active AP selection algorithm of deactivating APs one by one until no more AP can be deactivated. Due to the limited transmission capacity in WIMNET, we further present an algorithm extension for throughput maximization. We verify the effectiveness of our proposal through simulations in three instances, where the number of active APs is reduced by more than 40% and the throughput is improved by more than 10% from the original in any instance.
