Many problems in reality take the forms of complex networks and their underlying organization exhibit the property of containing communities, i.e. groups of tightly internally-connected and sparsely externally-connected nodes in the network structure. Community detection is the problem of identifying those communities in a given network with or without extra information such as the number of communities, and with overlapping or non-overlapping communities.

Objectives:

• Community detection methods are of great advantages in social-aware routing in MANETs and worm containment on social networks.
