In order to evaluate the performance of the network system in MANET field experiments, we have to understand the network topology among mobile terminals in real time and conduct the field experiments efficiently. In this paper, we design a system to visualize a network topology and packet flow in real time, and implement it in Android terminals for MANET field experiments. In case that Android terminals...
Mobile ad hoc networks (MANETs) that consist of smartphones can be configured easily because most of them are equipped with cellular (3G/LTE) connections as well as WiFi/Bluetooth connections, and then new network systems and services over MANETs can be developed and implemented. However, the performance of the new network systems and services should be evaluated in MANET field experiments. In this...
We have been studying and developing dual-purpose systems, which are available in both normal and disaster situations, and which are based on the assurance network design principle. The assurance network design principle makes the dual-purpose systems work stably in both normal and disaster situations. Also we have developed a prototype of network applications for such systems. The prototype has two...
In the Hiroshima National Confectionery Exposition which was held from April 19 to May 12, 2013 in Hiroshima, people who participated in the Expo sampled a wide variety of confectioneries and assessed variously, for example, they are sweet and beautiful. The assessment information acquisition and dissemination system proposed by us disseminates the information using store-and-forward data transmission...
