Monitor observation is possible by inserting sensor nodes in network, and monitor these nodes behavior. Sensor nodes placed in network gather information about states of nodes as discussed in Section 1.5.1.2.3. Monitor observation is one of the factors and is useful in identifying source in network. There is chance of missing information about some nodes where sensor nodes are not placed and if number of sensor nodes increases then system performance decreases. But if this observation is considered for source identification, then on collected information use rumor centrality measures to find source of rumor either in tree-like network or general network. In Ref. [49] proposed sensor nodes do not contain any textual information in the network to detect rumor source.

The above three observations are used to detect RS in social networks.
