“…However, the coupling of one objective to another due to the commonality in the sets of their controlling parameters is still a problem to be addressed. Some authors [154] are of the opinion that a complex coordination plane is inevitable to overcome this challenge. This coordination plane may affect the scalability of the SO solutions.…”

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.

Thus a need for a coordination mechanism has been highlighted in [2] which have split the optimization parameters into different functional groups based on correlation.…”

Abstract-Mobile services have seen a major upswing driven by the bandwidth hungry applications thus leading to higher data rate requirements on the wireless networks. Spectrum being the most precious resource in the wireless industry is of keen interest. Various spectrum assignment and frequency reuse schemes have been proposed in literature. However in future networks, dynamic schemes that adapt to spatio-temporal variation in the environment are desired. We thus present a hybrid spectrum assignment scheme which adapts its allocation strategies depending on user distribution in the system. Results show that the proposed dynamic spectrum assignment strategy improves spectrum utilization thereby providing a higher data rate for the users.

“…In contrast to traditional network operation, the execution of SON function instances is individual and dynamic (i.e., not planned). Therefore SON function instances can have run-time interactions with each other ( [2], [3], [4] Chapter 9). A negative interaction is called a conflict.…”

Abstract-Self-Organizing Mobile Networks contain a potentially large number of SON function instances that need to be coordinated in order to achieve system-level operational goals. Many SON functions (and thus their coordination) will be realized in a centralized way (C-SON) due to the required integration with a (centralized) legacy OAM system. In such systems, many configuration requests ("batches") are treated in regular time intervals For SON functions, this may lead to undesired effects (monopolization by high priority functions and frequent rollbacks of configuration actions). This paper proposes a novel coordination approach combining an output buffer of pending configuration requests with dynamic priorities for different SON function types. A simulated network scenario exhibiting a specific optimization problem (closure of a coverage hole) is used to evaluate the proposed method. The method is able to avoid the undesired effects and approximate legacy workflows in network optimization while still keeping the autonomous characteristic of SON functions.
