Online recommendation systems provide useful information to users on various products and also allow the users to rate the products. However, they do not usually consider the fact that users trust their connections more than others and that the trusts vary from connection to connection i.e., we value the opinions of our connections differently. Moreover, the importance of connections' opinion changes...
This letter investigates inter-arrival time, dwell time distributions and other mobility patterns in mobile cellular networks. It has been generally assumed and widely accepted that both inter-arrival time and dwell time distributions can be well approximated by exponential distribution. However, based on real cellular data measurements, we evaluate the fitness of various typical statistical distributions...
The vertex connectivity of many large networks follows a scale-free power-law distribution. BA model and many other BA-derived models reproduce such property and acquire a special status. The most distinct characteristic of these models is that during the preferential attachment process the choice of old vertices is based on the connectivity of the old vertices and there is no relationship between...
