This article surveys the literature over the period of the last decade on the emerging field of self organisation as applied to wireless cellular communication networks. Self organisation has been extensively studied and applied in adhoc networks, wireless sensor networks and autonomic computer networks; however in the context of wireless cellular networks, this is the first attempt to put in perspective the various efforts in form of a tutorial/survey. We provide a comprehensive survey of the existing literature, projects and standards in self organising cellular networks. Additionally, we also aim to present a clear understanding of this active research area, identifying a clear taxonomy and guidelines for design of self organising mechanisms. We compare strength and weakness of existing solutions and highlight the key research areas for further development. This paper serves as a guide and a starting point for anyone willing to delve into research on self organisation in wireless cellular communication networks.

Abstract-A fundamental challenge in Orthogonal FrequencyDivision Multiple Access (OFDMA) based cellular networks is Inter Cell Interference Coordination (ICIC) and to meet this challenge, various solutions using Fractional Frequency Reuse (FFR) have been proposed in the literature. However, most of these schemes are either static in nature, dynamic on a large time scale or require frequent reconfiguration for event driven changes in the environment. The significant operational cost involved can be minimised with the added functionality that Self Organising Networks (SON) brings. In this paper, we propose a solution based on the Centre of Gravity (CoG) of users in each sector. This enables us to have a distributed and adaptive solution for interference coordination. We further enhance our adaptive distributed FFR scheme by employing Cellular Automata (CA) as a step towards achieving an emergent self organised solution. Our proposed scheme achieves a close performance with strict FFR and better performance than SFR in terms of the edge user's sum-rate.

This paper looks at the implications, benefits and opportunities for integrating satellite links into the Future Internet specifically to provide resilient backhauls in the 5G networks that will emerge. This analysis is based on the study performed under ESA ARTES 1 "Service delivery over integrated satellite and terrestrial networks", contract 4000106656/12/NL/US. This study considered the integration of satellite networks with the Future Internet and 4G networks. This paper extrapolates this ESA study to providing 5G resilient backhaul links. It identifies a number of operator and user benefits for such integration and shows that modern satellite networks can be readily integrated to support the emerging standards

Recently both academic and industry worlds have started to define the successor of Long Term Evolution (LTE), so-called 5G networks, which will most likely appear by the end of the decade. It is widely accepted that those 5G networks will have to deal with significantly more challenging requirements in terms of provided bandwidth, latency and supported services. This will lead to not only modifications in the access segment and parts of core networks, but will trigger changes throughout the whole network, including the Back-haul segment. In this work we present our vision of a 5G Back-haul network and identify the associated challenges. We then describe our Wireless Back-haul (WiBACK) architecture, which implements Software Defined Network (SDN) concepts and further extends them into the wireless domain. Finally we present a brief overview of our evaluation results.
