BSS: A Distributed Top-k Processing in Mobile BusNet for Security Surveillance
We consider distributed top-k processing problem in a mobile scenario. Specially, we focus on a real application of a bus network (N nodes), where buses are equipped with cameras for real-time security surveillance. Due to the limited number of screens (k, k<
