An efficient voice over internet telephone call network (TCN) model based on user perspective for analyzing the dynamic behavior of the telephone calls

An appropriate telephone call network (TCN) model is very important for any VoIP provider to analyze the practical scenario of the telephone network. Telephone call network model on user perspective is another significant research area as this type of model is particularly useful in predicting the dynamics of the telephone calls during incidents like earthquakes or typhoons, when there is a sudden surge in the number of telephone calls. Again telephone call network (TCN) model on user perspective plays significant importance in detecting spam call. It is found that in a telephone network, the call distribution over the user is not uniform. Some users originate or receive more calls than others. Again, real-life data have proved that the number of calls received by a user in a network has a power-law property. Another important perspective is that usually the receiver of a call is found from the neighbor group of the caller as people generally make call to others whom they know. In this paper, we have analyzed and develop the appropriate telephone call network model considering all these real-life user behavior in a VoIP telephone network.
