In the paper, we concentrate on the influence of heterogeneity on the performance of forwarding algorithms under opportunistic networks. Therefore, we first describe two different heterogeneous network models, and capture the heterogeneity which concern mobile nodes’ contact dynamics under the individual models and the spatial models. Then we investigate inter-contact time is not fully follow exponential...
Understanding the dynamic traffic and usage characteristics of data services in cellular networks is important for optimising network resources and improving user experience. Recent studies have illustrated traffic characteristics from specific perspectives, such as user behaviour, device type, and applications. In this paper, we present the results of our study from a different perspective, namely...
