A Geography-Intimacy-Based Algorithm for data forwarding in Mobile Social Networks

Chinese Journal of Electronics 2016年第5期25卷 936-942页

作者： ZHENG Yi ZHANG Dafang XIE Kun College of Computer Science and Electronic Engineering Hunan University

Due to uncertain network connectivity, efficiently data forwarding in Mobile social networks(MSNs)becomes challenging. To conquer the problem, an Efficient data forwarding scheme based on geography intimacy(GIDF) for MSNs to achieve higher delivery ratio is proposed. In GIDF, we firstly propose an Intimacy based dynamic community detection algorithm(IDCD), which divide the MSNs into several communities. We propose a novel metric geography intimacy which can quantify the node's geographical information and the friendships between nodes. Based on geography intimacy, we further propose a routing algorithm to forward data. Compared with the geography intimacy between nodes, the next hop is found, further find the route of data forwarding by doing the similar operations. Extensive simulations on real data with the ONE simulator show that GIDF is more efficient than the existing algorithms.

Trajectory-Based data forwarding Schemes for Vehicular Networks

ZTE Communications 2014年第1期12卷 17-25页

作者： Jaehoon (Paul) Jeong Tian He David H.C.Du Department of Software Sungkyunkwan University Department of Computer Science and Engineering University of Minnesota

This paper explains trajectory-based data forwarding schemes for multihop data delivery in vehicular networks where the trajectory is the GPS navigation path for driving in a road network. Nowadays, GPS-based navigation is popular with drivers either for efficient driv- ing in unfamiliar road networks or for a better route, even in familiar road networks with heavy traffic. In this paper, we describe how to take advantage of vehicle trajectories in order to design data-forwarding schemes for information exchange in vehicular networks. The design of data-forwarding schemes takes into account not only the macro-scoped mobility of vehicular traffic statistics in road net- works, but also the micro-scoped mobility of individual vehicle trajectories. This paper addresses the importance of vehicle trajectory in the design of multihop vehicle-to-infrastructure, infrastructure-to-vehicle, and vehicle-to-vehicle data forwarding schemes. First, we explain the modeling of packet delivery delay and vehicle travel delay in both a road segment and an end-to-end path in a road net- work. Second, we describe a state-of-the-art data forwarding scheme using vehicular traffic statistics for the estimation of the end-to- end delivery delay as a forwarding metric. Last, we describe two data forwarding schemes based on both vehicle trajectory and vehicu- lar traffic statistics in a privacy-preserving manner.
