We study the collaborative data offloading problem for earth observation satellite networks (EOSNs) that allows light-loaded satellites to assist heavily-loaded ones offload data. First, we propose a task flow graph (TFG) depict procedure. Based on proposed TFG, formulate studied as integer linear programming (ILP) maximize weighted sum of successfully offloaded tasks. Then, leverage underlying structure ILP fast yet efficient algorithm. Finally, our simulation results demonstrate can...
Bluetooth Low Energy Mesh (BLE Mesh) is a promising protocol to interconnect massive transceivers in low-power, high-flexibility and wide-coverage way. It applies managed flooding realize efficient many-to-many communication, especially the small packet scenario. However, traditional approaches usually generate too much redundant packets, resulting severe collision even broadcast storm. Related works deal with this problem mainly from aspects of transmission mode, probabilistic node...
An electromagnetic simulation model of REPMM under normal state was built and the modified to accommodate diversified faults including converter switch fault, winding fault hall effect position sensor fault. The were simulated performance waveforms relevant different obtained. Characteristics recognized by comparing faulty states those state. Results analyzed references diagnosis strategies coordinate control for lunar rover's wheels provided.
Recent research shows that antenna correlation plays a crucial role in diversity and capacity of MIMO system. In order to obtain lower coefficient many methods have been developed, e. g.. using antennas orthogonal polarization for transmitter or receiver. But few paper considers the arrays with arbitrarily oriented antennas. this kind arrays, each element has different radiation pattern. paper, we express closed form function two This array will cause then z-axis array. Our work gives...
The present study evaluated the β recrystallization behavior and deformation microtexture evolution of TB6 titanium alloy (Ti-10V-2Fe-3Al) taking place during isothermal compression. hot tests were carried out in temperature range below phase transition spanned a wide strain rate 0.0001~1 s−1. Microstructure on phase, including its formation, is sensitive to rates, whereas average grain size equiaxed α exhibits slight increase with decreasing. Moreover, not homogeneous among prior grains,...
The unmanned aerial vehicle (UAV) swarm is a self-organizing composed of multiple UAVs, and achieves mission objectives in an adaptive way. At present, the model UAV based on complex network. Each represented as node, each link represents information exchange between UAVs. However, existing researches do not consider cascading failure phenomenon swarms, that is, one or more nodes network will propagate to other through connection nodes. In this paper, combined with characteristics...
Internet of Things (IoT) is a promising technology for realizing massive interconnection, especially when it enabled by Unmanned Aerial Vehicles (UAVs) in terms flexibility and operability. However, limited cache resources channel limit the implementation high throughput low loss communication systems. Furthermore, order to better user experience system resource utilization, imperative different services acquire individualized configurations. This paper proposes Service-Oriented Resource...
As the number of antennas goes large in massive multiple-input multiple-output (MIMO) scenario, large-scale fading plays an increasingly important role system performance. In this paper, we investigate uplink sum rate a distributed MIMO over composite channels portrayed by Rayleigh–Lognormal (RLN) model, where both zero forcing (ZF) and ZF decision-feedback receivers are considered. By exploring novel generalized method based on integral limit theories, is expressed as series with regard to...
