In this paper, we propose a distributed joint relay selection and power allocation scheme in wireless multi-hop cooperative networks, taking both instantaneous channel state information (CSI) and relay nodes' residual energy into consideration. Specifically, we formulate the cooperative relaying network as a restless bandit system, which has been successfully applied in stochastic control and operations...
In this paper, we propose a distributed best-relay node selection scheme to maximize the achievable data rate for cooperative communications over underlay-paradigm based CR networks, and meanwhile guarantee that the primary link is provided with a minimum-rate for a certain percentage of time. Specifically, we formulate the CR relay network as a restless bandit system, where the finite-state Markov...
Most previous work in CR relay networks concentrates on maximizing physical layer QoS (e.g., capacity, spectral efficiency and achievable data rate) as relay selection criteria. However, the energy state of relay nodes is largely ignored, which has significant effects on the network lifetime. This paper proposes a distributed relay selection scheme for cooperative transmissions over underlay CR networks,...
Post-evaluation of wind power construction project has great significance to improve the project decision-making and management, it is the urgent need to improve on post-evaluation theory and method. This paper builds the post-evaluation management system based on the study of post-project evaluation theory, which is suitable for the characteristics of wind power projects, describes indicators, methods...
This paper studies the methods and strategies of the network update of the land survey spatial data based on embedded terminal equipment and server and application of multi-level distributed heterogeneous land spatial database.Web services network model has been used to do the design and implementation work of embedded system of land survey data update. The main procedure of spatial data real-time...
