TDMA Scheduling in Long-Distance WiFi Networks

In the last few years, long-distance WiFi networks have been used to provide Internet connectivity in rural areas. The strong requirement to support real-time applications in these settings leads one to consider TDMA link scheduling. Such scheduling takes on a different flavour in long-distance mesh networks due to the unique spatial reuse pattern. This paper considers the FRACTEL architecture for long-distance mesh networks. It propose and substantiate a novel angular interference model. This model is not only practical, but also makes the problem of TDMA scheduling tractable.
