Evaluation of shared bandwidth for mobile multimedia networks using a diffusion model
This letter proposes a diffusion model that considers hath mobility and multimedia based on the user population process to examine the effects of multimedia in mobile communications. As an application example of this model, the shared bandwidth that can be used by one user in packet communications is evaluated. In this model, the user speed and variation in the number of users in a cell are interrelated with respect to mobility. By examining the shared bandwidth behavior based on multimedia teletraffic characteristics assuming that the number of simultaneously-communicating users within a cell have selfsimilarity, we found that shared bandwidth and its variance are not dependent on self-similarity but that variance in the shared bandwidth is dependent on user speed.
