With the rapid development of new applications and services in vehicular environment, there is an increasing demand for mobile users to access data items. Moreover, Road Side Unit (RSU) has been introduced by researchers to facilitate data dissemination in Vehicular Ad-hoc Networks (VANETs). Therefore, it is necessary to design a data access scheme for vehicle-to-roadside (V2R) communications. However,...
Network virtualization has been recognized as a promising solution to enable the rapid deployment of customized services by building multiple Virtual Networks (VNs) on a shared substrate network. Whereas various VN embedding schemes have been proposed to allocate the substrate resources to each VN requests, little work has been done to provide backup mechanisms in case of substrate network failures...
Exploiting path diversity to enhance communication reliability is a key desired property in Internet. While the existing routing architecture is reluctant to adopt changes, overlay routing has been proposed to circumvent the constraints of native routing by employing intermediary relays. However, the selfish inter-domain relay placement may violate local routing policies at intermediary relays and...
The features of P2P networking architecture can contribute to robustness and scalability, however, it also introduces network-oblivious traffic, which brings big pressure to the ISPs. Meanwhile, since traffic of P2P applications occupies much of bandwidth in bottleneck links, non-p2p applications may be severely harmed due to lack of bandwidth. To conquer this problem, previous works mainly focused...
