Evaluating performance of two-hop routing in DTN based on Home-MEG model

Performance analysis in delay tolerant networks (DTN) is often based on unrealistic mobility models. Recently, the Home-MEG model is proposed. This model is able to accurately reproduce the power law and exponential decay distribution of inter-contact times between mobile nodes which has been observed in many real motion traces. This letter proposes a theoretical framework to evaluate the performance of two-hop routing based on Home-MEG model for the first time. Simulation results show the accuracy of our theoretical model. Using the model, we explore the impact of some parameters (e.g. the number of relay nodes) on the routing performance.
