Message routing in mobile delay tolerant networks inherently relies on the cooperation between nodes. In most existing routing protocols, the participation of nodes in the routing process is taken as granted. However, in reality, nodes can be unwilling to participate. We first show in this paper the impact of the unwillingness of nodes to participate in(More)
In mobile Delay Tolerant Networks (DTNs), messages are routed in a mobility-assisted manner. Therefore, the willingness of nodes to relay messages for other nodes plays a significant role in the routing process. Moreover, since the resources in mobile devices are generally limited, carriers of mobile devices may be unwilling to relay messages for other(More)
Previous studies demonstrated that the loss of function of the CDKN2A/p16/INK4A gene is mainly caused by the hypermethylation of CDKN2A, however, whether or not it is associated with the incidence and clinicopathological characteristics of endometrial carcinoma (EC) remains unclear. In this study, we conducted a meta-analysis aiming to comprehensively(More)
A prediction-based routing protocol for mobile delay tolerant networks functions by forwarding a message from one intermediate node to another if the latter has higher probability of encountering the destination node. However, this process compromises the privacy of the nodes by revealing their mobility patterns. In this paper, we propose a privacy(More)
In this paper, we present a novel routing protocol for mobile delay tolerant networks, called Community-based Adaptive Spray (CAS). How to maximize routing performance (delivery ratio) and minimize resource consumption (number of message copies) is a common goal in these networks. Our protocol considers the following two aspects toward this goal: 1)(More)
The increasing pervasiveness of mobile devices with networking capabilities has led to the emergence of Mobile Delay Tolerant Networks (MDTNs). The characteristics of MDTNs, which include frequent and long-term partitions, make message routing a major challenge in these networks. Most of the existing routing protocols either allocate an unlimited number of(More)
Solutions for data dissemination in traditional peer-to-peer networks are not suitable for mobile peer-to-peer networks due to the special characteristics of mobile environments, particularly highly variable connectivity, and disconnection. Mobile peer-to-peer data dissemination over Delay Tolerant Networks (DTNs) is a promising paradigm since they can(More)
The vehicular ad-hoc network (VANET) aims to make road traffic safer and more efficient. Security and privacy are two important but somewhat contradictory objectives. On the one hand, vehicle-to-vehicle (V2V) authentication requires drivers to present some individual credentials. On the other hand, drivers need privacy protections on their identities,(More)

Delay tolerant networks (DTNs) are wireless mobile networks in which the existence of an end-to-end path from the source to the destination of a message cannot be guaranteed. This makes message delivery as one of the major challenges in DTNs. Recent studies based on real world traces show that nodes in DTNs exhibit mobility properties such as their(More)
