Based on comparative analysis, a new LSA evolution concept and functional architecture is proposed, and the early results of the world first LSAevo validation are presented. Introduced system architecture can be applied to 3.4-3.8 GHz band so that
fragmentation challenges to take the band into 5G use in the European member states can be solved, while ensuring that the communication of the incumbent users, fixed wireless access, fixed links, and satellite earth stations do not experience any harmful interference. In the end-to-end field trial, local high-quality wireless network use case for an industrial
automation Micro-operator is validated.

for spectrum sharing by focusing on the regulatory framework that has been deployed by the Federal
Communications Commission (FCC) for the 3.5GHz band. Pairing this regulatory approach with WNV
permits us to present a sharing proposal where emphasis is made on increasing resource availability and providing flexible methods for negotiating for resource access. We include an economics framework that aims at presenting an additional perspective on the attainable outcomes of our sharing proposal. We find that by pairing regulatory flexibility with an enabling technology, within an appropriate economics context, we can increase resource access opportunities and enhance current sharing arrangements.

Abstract:
In this paper, we propose a cross-domain optimization (CDO) scheme, which optimizes the MANET topology and enables communication between multiple MANETs via LTE. Particularly, we first deploy a gateway to the center of gravity of all nodes in each MANET so that the network topology is optimized. …In this paper, we propose a cross-domain optimization (CDO) scheme, which optimizes the MANET topology
and enables communication between multiple MANETs via LTE. Particularly, we first deploy a gateway to the
center of gravity of all nodes in each MANET so that the network topology is optimized. Thus, the aggregation cost of intra-MANET traffic in the gateway is improved. Likewise, we then deploy an eNodeB in the center of gravity of all gateways to establish communication connections between multiple MANETs via LTE. Then, the aggregation cost of inter-MANET traffic at eNodeBs can be largely reduced because of the minimization of the distances between eNodeBs and gateways, along with a significant performance improvement of inter-MANET communications owing to the superiority of LTE. Vis extensive simulations, we validate the effectiveness of our proposed scheme. Our experimental results demonstrate that the CDO scheme can greatly improve network performance. Finally, we discuss some other issues.

Abstract:
The majority of existing spectrum prediction models in Cognitive Radio Networks (CRNs) don’t fully explore the hidden correlation among adjacent observations. In this paper, we first develop a novel prediction approach termed high-order hidden bivariate Markov model (H2BMM) for a stationary CRN. …The majority of existing spectrum prediction models in Cognitive Radio Networks (CRNs) don’t fully explore
the hidden correlation among adjacent observations. In this paper, we first develop a novel prediction
approach termed high-order hidden bivariate Markov model (H2BMM) for a stationary CRN. The proposed
H2BMM leverages the advantages of both HBMM and high-order, which applies two dimensional parameters,
i.e., hidden process and underlying process, to more accurately describe the channel behavior. In addition, the current channel state is predicted by observing multiple previous states. Afterwards, the mobility of secondary users is fully considered and we propose an advanced approach based on H2BMM, termed Advanced H2BMM, to accommodate a mobile CRN. Extensive simulations are conducted and results verify that the prediction accuracy is significantly improved using the proposed (H2BMM. The Advanced H2BMM is also evaluated with comparison to H2BMM and results show considerable improvements of H2BMM in a mobile environment.

In order to analyze the communication distance of UWOC, the performance of optical transmitter and receiver, underwater channel characterization and modulation schemes were discussed. The communication link model was established based the
on Beer-Lambert Law. The suitable transmitter power and the maximum communication were achieved in order to achieve communication rate to 1Mbits/s and bit error rate to 10-6.This paper not only provides comprehensive understanding of UWOC, but also aims to provide a theoretical foundation for designing the underwater wireless optical communication system and optimizing the system parameters.
