What Does Cognitive Network Mean?

A cognitive network is a network that uses cognitive processes to perceive current internal conditions, make decisions based on its findings and then learn from those decisions. A cognitive network is different from other intelligent communicational technologies because it has its own end-to-end goal regarding data flow and is designed to go beyond self-modification.

Techopedia Explains Cognitive Network

A cognitive network runs parameters of varied layers in the protocol stack. In this kind of network, its protocol are further divided into joint-layer optimization design and cross-layer adaptive design, which is why it can accomplish more than an ordinary cross-layer design.

A cognitive network uses a networking architecture called Embedded Wireless Interconnection (EWI). A cognitive network uses abstract wireless linkages in which each link is created arbitrarily and can be redefined as needed.

Traditional networks work with wireless linkages using predetermined links acting as virtually wired links. There are certain requirements that must be met in order for a network to be cognitive. First, it should perform high level end-to-end work over a long period of time. Second, being a cognitive network gives an improved Quality of Service (QoS), secured communication, control over access and other general networking goals.
