An Overview of Self-Organizing Networks (SON) in Wireless Networks

Abstract

The latest trend in technological aspect in the arena of telecommunicationsis the progression of Long TermEvolution(LTE) and LTE-Advance that assures exceptional performance and a promising market in the wireless network (WN) domain. Tofulfill promises, new features have been appended with every new release (Release 8, Release 9). This paper aims to give an outline of the Self-Organizing Network (SON) function that was proposed in LTE and carried further to LTE-Advance. There are many beneficial factors about SON like Automatic Neighbor Relation (ANR), Automatic updates, Automatic recovery, adjustment in parameters as per change in the network environment that have been reviewed. The different kinds of architecture that can be applied depending on SON functions have been explained. There are many questionable aspects of SON which have been introduced as its limitations,along with the scope of SON functions in the future in alliance with the developing network.
