Enhanced with wireless power transfer capability, cloud radio access network (C-RAN) enables energy-restrained mobile devices to function uninterruptedly. Beamforming of C-RAN has potential to improve the efficiency of wireless power transfer, in addition to transmission data rates. In this paper, we design the beamforming jointly for data transmission and energy transfer, under finite fronthaul capacity...
Quality of Service (QoS) routing is one of the key enabling techniques for multimedia wireless sensor networks (WSNs). However, the multi-constraints QoS routing problem is an NP-hard problem, and the computational complexity of an exhaustive search over all the paths is too high for large scale multimedia WSNs. In this paper, a novel parallel elite clonal quantum evolutionary algorithm is proposed...
In fire fighting having prompt and reliable tracking and communication in case of emergency is of paramount importance. We developed an integrated positioning, sensing and communication platform for tracking first responders in urban fire fighting. A Quality of Service (QoS) enabled TDMA MAC (QT-MAC) was designed to provide a low latency and high reliability service for critical data transfer, as...
