self organized network (SON)

Self-organized networks(SONs) exist in ad hoc networks, IP-basedpeer-to- peer networks, WLANs, mesh networks and higher-generation mobile networks. These SON networks decide on the cooperation of the nodes with neighboring nodes according to their own algorithms. They decide themselves based on experience with whom to cooperate and with whom not to cooperate. The experiences and recommendations can be economic, social or computer-technical.

Self Organized Networks (SON) simplify the configuration, management and optimization of networks. SON networks are about self-configuration of added network components, self-optimization, and restoration of functionality in case of failure.

As far as self-configuration is concerned, it is plug-and-play, so that newly added base stations configure themselves automatically. Since cellular networks are subject to constant changes in field strength, throughput, user behavior, number of subscribers, etc., these networks respond to these changes by changing their configuration within a predefined framework and communicating these changes to the network center.

Self-optimization first uses Automatic Neighbor Recognition( ANR) to connect to the neighbor node. It receives exact configuration parameters from other base stations. When recovering from faulty functions, SON networks relied on adjusting parameters in neighboring radio cells. Thus, a SON network can change the relationship with the neighboring node or radio cell if, for example, a base station fails to reroute traffic accordingly, or a new radio cell is inserted to relieve traffic congestion.

In mobile communications technology, SON concepts are used in High Speed Packet Access Plus( HSPA+), in Long Term Evolution Advanced( LTE-A), and in 5th generation ( 5G) mobile networks, among others.
