This paper presents a scalable and robust scheduling algorithm for a set of wireless stations. Recently, road-side access points for vehicular networks and outdoor WiFi stations are deployed in wide urban areas and compete with each other for limited wireless resources. We focus on pursuing the best balance among (i) optimality of resource utilization, (ii) robustness to new station installation and...
To support rescue activities of first responders is crucial at disaster sites. Especially, provisioning location and situation information is indispensable for those first responders to efficiently rescue injured people in unknown places with a lot of buildings such as private properties (like factories) and university campus. In such an extreme situation, seamless indoor/outdoor maps will be of substantial...
The electronic triage system developed by our research group is a wireless sensor network, constructed by electronic triage tags composed of vital sign sensors and ZigBee modules. The system assumes a network of hundresds of patients, simultaneously transmitting data to a remote sink. We have investigated the performance of a simple data collection mechanism in real scenarios, based on IEEE 802.15...
