- 20. Six Degrees ofSeparation
- 21. Six degrees ofseparation Theory In 1929, Hungarian author Frigyes Karinthy in one of his short stories titled Chains, said that “With growing communication and travel, the friendship network would grow irrespective of the distance between two humans.” “The social distance would shrink immensely.” “All the people on the planet could be connected to one another by 5 or fewer people.” This theory captivated millions of mathematicians, sociologists, and physicists and also laid the founding stone of the first online social network. Soon, several “small world” projects were conducted.
- 22. Small world phenomenon •The first significant empirical study of the small-world phenomenon was undertaken by the social psychologist Stanley Milgram. • He chose random people & told them to Forward a letter only to people they know on a first-name basis. • He provided the target’s name, address, occupation, and some personal information, but insisted that the participants could not mail the letter directly to the target.

- 26. Present Scenario • In2011, Facebook and researchers computed that, the average separation across 721 million people using Facebook was only 3.74. • In their research published in February 2016, this number dropped down to 3.57, with more than 1.59 billion people active on Facebook. • On average, Facebook users are connected by 2.9 to 4.2 degrees of separation.
- 27. • Facebook mentionsthat this estimation was done using the Flajolet–Martin algorithm. • With a growing social network, the average separation and connection would soon reduce to possibly 2 to 3 degrees of separation.
- 28. Social Network forIoT • M2M (Machine - to - Machine) communication. • The social aspect of a machine is its ability to form a network with other machines. • It includes information such as the machine's functional details and related neighbourhood details. • This allows other devices to offer their services to the mentioned device based on the needs (requirements), as well as offering services, data, and sensors.
