We consider the problem of allocating orthogonal resources in a self-organized manner on conflict graphs that describe discretized interference couplings of wireless networks. The target is to find a global optimum, i.e., a conflict-free allocation. We consider both random planar and nonplanar graphs that result from a path-loss model in a wireless network.… (More)

We consider distributed channel allocation on planar conflict graphs describing interference couplings of wireless networks. We observe that the corresponding graph colouring problem is riddled by topologic defects that are annihilated when they meet the network boundary, or possibly another defect. Greedy algorithms lead to random walk -like motion of… (More)
