Abstract: With the growing need for Internet connectivity in rural areas, an alternative to the wired technology need to be used to provide Internet connectivity because of cost constraint. Wi-Fi can be a cost effective and efficient solution to provide Internet connectivity in rural areas. Wi-Fi based long distance networks with long distance outdoor links have become an attractive option to provide low cost internet connectivity to rural areas. The existing MAC protocol, CSMA/CA used by Wi-Fi has its coverage on comparatively smaller range and this aspect puts a hurdle in providing Internet, when it comes to rural areas. So, for practical applicability of Wi-Fi in long distance networks, modifications need to be made in the MAC protocol. As this protocol is originally not fit for long distance Wi-Fi networks, we have taken an initiative to tune certain parameters in this protocol and proposed two algorithms (Pre_BackOff algorithm, BackOff algorithm) to make it acceptable operable for long distance Networks.
