What are the complex network models?
Complex networks are used to model real-world systems using sets of nodes and edges that represent elements and their interactions, respectively (the term ‘complex’ refers to any collection of interrelated things in which the pattern of links is meaningful1).
What is complex network theory?
Complex networks theory is a statistical physics interpretation of the old graph theory, aimed at describing and understanding the structures created by the relationships between the elements of a complex system [6–9].
What is meant by complex network?
In the context of network theory, a complex network is a graph (network) with non-trivial topological features—features that do not occur in simple networks such as lattices or random graphs but often occur in networks representing real systems.
Why are complex networks important?
Indeed, complex networks allow us to understand various real systems, ranging from technological to biological networks [1]. These systems are called complex systems because it is not possible to predict their collective behavior from their individual components.
What is the most complex network topology?
Tree Topology A hierarchical layout that links together groups of nodes. Creates parent-child dependencies between root nodes and regular nodes. This layout can be vulnerable to failure if a root node has a problem. This topology is complicated and difficult to manage and it uses a lot of cable.
Who developed complex network theory?
Famous mathematician Erdos and Renyi proposed a mathematical theory currently being called ER random graph model in 1959, and the model has been the basic model of complex networks research in nearly 40 years after that.
What is the best network topology for a large business?
star topology
The best cabled network topology for large businesses is the star topology. This is because it is easier to control from a central console as the management software just needs to communicate with the switch to get full traffic management features.
Which topology is the cheapest?
Bus topology is the easiest and cheapest type of topology to install. With a one-to-one ratio of devices to drop lines, this topology requires less cable than other topologies, reducing the installation time and expenses. Adding new devices to the network is also straightforward.
Which area network is more complex than other networks?
Wide Area Network (WAN) Slightly more complex than a LAN, a WAN connects computers together across longer physical distances. This allows computers and low-voltage devices to be remotely connected to each other over one large network to communicate even when they’re miles apart.
What network topology is used in computer shops?
Type of LAN Architecture Used The topology that is used by Trez Computer Shop was star topology. As compared to Bus topology, it gives far much better performance; signals don’t necessarily get transmitted to all the workstations.
Which network topology is the cheapest?

Which is the most expensive network topology?
Explanation: Star topology is the most popular way to connect a computer in a workgroup. It is expensive due to the cost of the hub. Star topology uses a lot of cables, which makes it the most costly network to set up as you also have to trunk to keep the cables out of harm.
