A node's centrality score is an index that identifies its importance inside a network. Depending on the goal of the study, different writers define different centrality measures. Numerous fields, including sociology, neurobiology, communication networks, electrical networks, etc., find use for these measurements. The goal of this work is to provide a thorough overview of degree, closeness, eigen vector, and betweenness centrality.

Keywords : Centrality Measure; Degree Centrality; Closeness Centrality; Eigen Vector Centrality; Betweenness Centrality.
