Abstract
A network device that determines RACH root sequences for AP devices within a given market. The network device can utilize a specialized graph coloring process or algorithm that has been adapted to, e.g., ensure that no two neighboring AP devices share the same RACH root sequences, provided certain additional constraints not found in graph coloring theory are met. For example, AP devices can have multiple RACH root sequence, whereas in traditional graph coloring problems, each vertex typically has only one color.
