VillageNet, the Bangalore initiative, is a low cost IEEE 802.11 WiFi based mesh network designed for connecting villages in rural India, providing low-cost broadband Internet access for wide regions. It targets the rural market around the world, where large populations live but paying capacities are low. VillageNet offers a low-cost, high performance alternative to traditional wireline and cellular technologies that have prohibitively expensive deployment costs. VillageNet connects villages in a mesh using long-distance wireless links. The cost of building the network is kept low by using off-the-shelf IEEE 802.11 equipment and optimizing the network topology to minimize cost.

Jaiswal spoke about the unique interference models for such point-to-point mesh networks, and then introduced challenges around channel allocation and scheduling of links in the network (which are independent of the underlying wireless technology – WiFi or WiMAX).

He also discussed network planning problems unique to such point-point mesh networks, and not surprisingly many of them were similar to the ones encountered in implementing the Mesh network at Mahavilachchiya.

Paper titled ‘Wireless Mesh Networking as a means of connecting rural communities: advantages, constrains and challenges – an analysis based on a case study from rural Sri Lanka’ co-authored by Chanuka Wattegama (LIRNEasia) and Rehana Wijesinghe (Enterprise Technology) has been accepted to be presented at the Wireless World Research Forum Meeting to be held 5-7 November, Chennai, India. 

The objectives of this paper are to discuss the appropriateness of Wireless Mesh Networking in a rural environment in empowering the community, the design and implementation challenges and how they were addressed, related policy issues including the unlicensing of 2.4 GHz and 5.1 GHz bands and explore the possibilities of replicating the Mahavilachchiya model. 

WWRF (http://www.wireless-world-research.org) is a global organisation, founded in August 2001 and now having over 140 members from five continents, representing all sectors of the mobile communications industry and the research community. The objective of the forum is to formulate visions on strategic future research directions in the wireless field, among industry and academia, and to generate, identify, and promote research areas and technical trends for mobile and wireless system technologies. 

The full paper will be available shortly.
