Hard energy constraints impose huge challenges to wireless communication under the constraint of communication delay. In this paper, we consider the problem of energy-efficient point-to-point transmission scheduling of delay sensitive multimedia data over a fading channel. We first formulate the transmission scheduling problem as a Markov Decision Process (MDP) and systematically unravel it by the...
In cognitive radio networks (CRNs), TCP goodput is one of the key issues to measure it's performance. However, most existing research efforts on TCP performance improvement have two weaknesses as follows: first of all, most of them only consider the underlying parameters to optimize the physical performance, the TCP performance have been neglected; Second, they are largely formulated as a Markov Decision...
Cognitive radio (CR) is an intelligent wireless communication system which can dynamically adjust the parameters to improve system performance depending on the environmental change and quality of service. The core technology for CR is the design of cognitive engine, which introduces reasoning and learning methods in the field of artificial intelligence, to achieve the perception, adaptation and learning...
