The building/environment data and information system (BeDIS) described here is a part of infrastructure needed to support location-specific, active emergency preparedness and responses within large buildings. Building/environment data and information (BeDI) based indoor positioning system (BeDIPS) is one of its components. BeDIPS can provide people in large buildings with sufficiently accurate location...
In addition to being able to provide accurate location information, indoor positioning services/systems (IPS) for large public buildings/facilities should be easy to deploy and maintain, stay scalable in response to surges in crowd density and location queries, minimize the capabilities required of user devices to use the service and degrade gracefully to be disaster resilient. This paper describes...
Synchronous e-training is emerging as an alternative for developing human resources training plans in large organizations. However, synchronous e-training platforms must face many issues affecting their resilience. Self-recovering and self-protection software techniques should be implemented to enable the continuity of e-training activities faced with network failures or entities of the platform going...
Synchronous e-training is emerging as an alternative for developing human resources training plans in large organizations. Real-time communications are used to emulate face-to-face interaction that occurs in on-campus learning environments. However, the security concerns that a synchronous e-training platform must face may compromise the integrity, availability and confidentiality of corporate information,...
Many large-scale distributed systems can benefit from a service that allows them to select among alternative nodes based on their relative network positions. A variety of approaches propose new measurement infrastructures that attempt to scale this service to large numbers of nodes by reducing the amount of direct measurements to end hosts. In this paper, we introduce a new approach to relative network...
