What is important in location-aware services is how to track moving objects efficiently. To this end, an efficient protocol which updates location information in a location server is highly needed. In fact, the performance of a location update strategy highly depends on the assumed mobility pattern. In most existing works, however, the mobility issue has been disregarded and too simplified as l...

The context in which a moving object moves contributes to the movement pattern observed. Likewise, the movement pattern reflects the properties of the movement context. In particular, big events influence human mobility depending on the dynamics of the events. However, this influence has not been explored to understand big events. In this paper, we propose a methodology for learning about big e...

The increasing amount of mobile phones that are equipped with localization technology offers a great opportunity for the collection of mobility data. This data can be used for detecting mobility patterns. Matching mobility patterns in streams of spatiotemporal events implies a trade-off between efficiency and pattern complexity. Existing work deals either with low expressive patterns, which can...

Since there has been little focus on systematically creating user mobility and communication pattern traces, researchers in the mobile networking community often propose personal models with which to validate their routing algorithms. This approach has two problems: (1) invalid conclusions may be drawn from overly simplistic or unrealistic models, and (2) it is difficult to compare performance ...

This paper describes an advanced simulation environment that has been used to examine, validate, and predict the performance of Protocols for IP Mobility Support. It overcomes many limitations found in existing network simulators, and it provides more support on mobile-related issues. It contains several components that are common to all evaluations of IP mobility, which can model arbitrary net...

Detection of pathogen by pattern recognition receptors leads to activation of inflammasome which plays a crucial role in immune system. The inflammasome regulates the release of cytokines, such as interleukin (IL)-1β, IL-18 and high-mobility group box 1 (HMGB1). Double-stranded RNA-dependent protein kinase (PKR) is a critical component of an inflammatory complex. Recently, the critical role of ...
