Modulo and grid based channel selection in ad hoc networks

In this paper, we describe several approaches to spatial-reuse in ad-hoc networks using multiple channels. We analyse many techniques requiring only information available locally and those that do not collaborate with neighbouring nodes. Our justification for this is to avoid extra network overhead. The results we obtain show that intelligent allocation of channels can make a significant performance improvement over that of simply using all available. We propose several approaches to allocating the channels intelligently and a grid-based approach that only requires Global Positioning information.
