人类的流动性已被证明对竞争网络（OppNets）的性能有重大影响。如在早期的工作中所示，地理限制的整合不仅是进一步提高OppNet模拟性能评估的可信度，而且还会影响相关指标，如联系持续时间和联系次数。在本文中，我们讨论并提出解决方案，以建模问题相关的地理限制和调查的影响，道路网络的情况下的地图提取。道路网络结构的多样性并没有显著影响相互接触时间（ICT），但东京密集的道路网络报告了相当短的时间和更少的接触，使其成为转发算法性能评估的一个特别具有挑战性的城市场景。
Human mobility has been shown to be of significant impact on the performance of Opportunistic Networks (OppNets). As shown in earlier work, the integration of geographic restrictions is not only a further step to more credibility of OppNet simulative performance evaluation, but also influences relevant metrics, such as contact duration and number of contacts. In this paper, we discuss and propose solutions to modeling issues related to geographic restrictions and investigate the impact of the road network underlying the scenario's map extract. Inter-Contact Times (ICTs) are not significantly impacted by the diversity in road network structure but considerably shorter and less contacts are reported for Tokyo's dense road network, making it an especially challenging urban scenario for forwarding algorithm performance evaluation.
