The pervasiveness of small mobile devices equipped with multiple wireless interfaces enabled novel communication paradigms: opportunistic data transfer between the mobile devices. In this paper, we consider the heterogeneity in forwarding mechanisms as one of the major reasons which affects the performance of forwarding algorithms. Heterogeneity arises in different contexts, for example in device...
Mobile Device Clouds are becoming a reality with the quantitative and qualitative upgrades on mobile devices such as smart-phones and tablets. This proliferation renders mobile devices capable of initiating sophisticated cyberattacks especially when they coordinate together and form a distributed mobile botnets which we call “MobiBots”. MobiBots infect a large number of mobile devices and schedule...
The fundamental challenge in opportunistic networking, regardless of the application, is enabling node cooperation in order to forward a message. While node cooperation is considered as a fundamental property in such networks, ensuring such a property between two devices in mobile opportunistic networks remains largely unexplored. In this paper, we investigate the potential impact of the lack of trust...
Social forwarding, recently a hot topic in mobile opportunistic networking, faces extreme challenges from potentially large numbers of mobile nodes, vast areas, and limited communication resources. Such conditions render forwarding more challenging in large-scale networks. We observe that forwarding techniques based on social popularity fail to efficiently forward messages in large scale networks...
The fundamental challenge in opportunistic networking, regardless of the application, is when and how to forward a message. Rank-based forwarding techniques currently represent one of the most promising methods for addressing this message forwarding challenge. While these techniques have demonstrated great efficiency in performance, they do not address the rising concern of fairness amongst various...
In opportunistic networks, end-to-end paths between two communicating nodes are rarely available. In such situations, the nodes might still copy and forward messages to nodes that are more likely to meet the destination. The question is which forwarding algorithm offers the best trade off between cost (number of message replicas) and rate of successful message delivery. We address this challenge by...
