We consider the Courier Delivery Problem, a variant of the Vehicle Routing Problem with time windows in which customers appear probabilistically and their service times are uncert...
Introducing mobile data sinks into wireless sensor networks (WSNs) improves the energy efï¬ciency and the network lifetime, and is demanded for many application scenarios, such a...
Abstract—WiFi-enabled buses and stops may form the backbone of a metropolitan delay tolerant network, that exploits nearby communications, temporary storage at stops, and predict...
