OFDMA-based network performs well in maximizing the overall throughput, and meanwhile, problems with security requirements are focused to satisfy the increasing needs of confidential data transmissions. According to information theory, however, secure transmission undesirably antagonizes larger flow rate, thus a tradeoff is expected to balance these two matters. In this paper, we consider a downlink...
Considering physical sensors with certain sensing capabilities in an Internet-of-Things (IoT) sensory environment, in this paper, we propose an efficient energy management framework to control the duty cycles of these sensors under quality-of-information (QoI) experience in a multi-task-oriented IoT sensory environment. Contrary to past research efforts, our proposal is transparent and compatible...
A priori knowledge of noise information at array sensors is necessary in the optimization procedure with aim of improving passive broadband detection performance of array. When several noise sources are present and/or an analytical expression of the noise transfer function is not available, the sensor noise needs to be measured in the optimization which is very demanding when an array with large number...
