To achieve a smart sensor network with Web-based sensor nodes such as Field Servers, we propose a hierarchical agent system that manages sensor nodes autonomously and flexibly, an...
While by now feasible solutions to protect privacy for complex ubiquitous applications are available, very small devices, called context transponders (CTP) still lack resources to...
The ubiquitous environment enables us to build systems that provide individual users with personalized navigation services in cities. In developing such a system, it is necessary ...
In recent years, it has been reported that several existing networks including the Internet have scale-free structure. In this paper, through a simple numerical analysis, we inves...
AQM (Active Queue Management) mechanism is a congestion control mechanism at a router for controlling the number of packets in the router’s buffer by actively discarding an arri...
