Impact of mobility on aggregate traffic in mobile multimedia system

In the wireless context, the underlying user behaviour together with the unpredictability of the air interface will have a high impact on traffic (both in space and time) shaping the traffic over the mobile network. We investigate the impact of mobility on the aggregate traffic for a wireless packet data networks in the city area of Bristol, UK, in order to show if the mixture of voice and data applications exhibit self-similarity. We also compare the queuing performance of these new data models with the traditional Poisson model to investigate how these new models affects the provisioning and dimensioning of future wireless data networks.
