This paper gives an introduction to a key tool that can help provide various self organised solutions in wireless cellu- lar networks. We begin by describing the need for self organised networks and the challenges associated with it. An introduction to cellular automata theory is then given with an easy to follow example. We provide an analysis of such solutions and discuss its stability and convergence criterion. Finally, we formulate a specific problem for Inter-Cell Interference Coordination (ICIC), describing how the cellular automata approach can be applied to achieve ICIC. In addition, we discuss the prospective use case of applying cellular automata in achieving energy efficiency in heterogeneous networks. This paper will serve as a guide for anyone willing to develop self organising solutions in wireless cellular networks.
