— In this paper, we propose a simple but effective VPN mechanism called RING-VPN (Ring-based Virtual Private Network) that realizes a high scalability in terms of the number of V...
The study in mobile ad-hoc networks (MANET) is facing challenges brought by recent discovery of non-exponential behavior of the inter-contact time distribution of mobile nodes. In...
— Search and rescue of people in emergency situations, e.g. lost hikers, stranded climbers, or injured skiers has been difficult due to lack of information about their location ...
The purpose of this work is to automate the analysis of ad hoc routing protocols in the presence of attackers. To this end, a formal model of protocol behavior is developed in whi...
This paper introduces a novel probabilistic activity modeling approach that mines recurrent sequential patterns from documents given as word-time occurrences. In this model, docum...
