Bluetooth is a low-energy consumption communication technology and a prospective communication method for emergency situations. A Classic Bluetooth communication network has been proposed and designed to establish an emergency mobile ad hoc network (hereinafter referred to as Classic Bluetooth MANETs). In Classic Bluetooth MANETs, a terminal can cause an excess of connection retries and connection...
The assurance network design principle makes systems work stably in both normal and disaster situations. We have been studying and developing assurance-based dual-purpose systems, which are available in both normal and disaster situations. Also we have developed a prototype of network applications for such systems. The prototype has two types of graphical user interface (GUI) for both situations....

Mobile ad hoc networks (MANETs) are networks consisting of wireless communication terminals such as cell phones and smartphones without any communication infrastructures (e.g. base stations). Therefore, MANETs can be utilized for networks in disasters. Moreover, there are some MANET-oriented applications that are developed for day-to-day life. In this paper, we propose a new self-organized communication...
Summary A novel cyclic macromonomer based on a cyclic polystyrene was prepared. Its radical copolymerization with vinyl acetate was carried out to give a mechanically cross-linked poly(vinyl acetate) which was converted to a mechanically cross-linked poly(vinyl alcohol) with high swellability.
