Network structure can be derived from two parameters: network topology and network observation [9]. Network topology describes the structure of network either in tree or graph. Source identification is more complex in the graph topology than tree topology, as tree has exactly one root node and no loops are allowed, Graph doesn’t have any root node and loops are allowed in network. Network observation is the second type of network structure and it is useful to observe the network during rumor propagation to get the knowledge about states of nodes in particular time. Network can be observed possibly in following three ways [11]: Complete, Snapshot and Monitor.
