Abstract (sommario):
Approved for public release; distribution is unlimited<br>This thesis solves the problem of a lack of a complete, simple ground station network interface standard. A federated satellite ground station network (FGN) model and computer interface are developed that extend the use of ground stations to external users across the Internet. This should allow for reuse of existing ground stations, reducing costs and complexity of space missions. An improved model describing FGNs is proposed that defines a hierarchy of the components of the network, allowing for scalability and unified interfaces, and

Abstract (sommario):
Federated approach for the distributed simulation of a network, is an alternative method that aims to combine existing simulation models and software together using a Run Time Infrastructure (RTI), rather than building the whole simulation from scratch. In this study, an approach that significantly reduces the inter-federate communication load in federated simulation of communication networks is proposed. Rather than communicating packet-level information among federates, characteristics of packet flows in individual federates are dynamically identified and communicated. Flow characterization

An information technology that can combine the physical world and virtual world is desired. The Internet of Things (IoT) is a concept system that uses Radio Frequency Identification (RFID), WSN and barcode scanners to sense and to detect physical objects and events. This information is shared with people on the Internet. With the announcement of the Smarter Planet concept by IBM, the problem of how to share this data was raised. However, the original design of WSN aims to provide environment monitoring and control within a small scale local network. It cannot meet the demands of the IoT becaus

Federated learning faces a challenge when dealing with highly heterogeneous data and it can sometimes be inadequate to adopt an approach where a single model is trained for usage at all nodes in the network.

Federated learning poses a statistical challenge when training on highly heterogeneous sequence data.

These distinct distributions are an inconvenience when a node not only plans to contribute to the creation of the global model but also plans to apply it on its local dataset. In this scenario, adopting a one-fits-all approach might be inadequate, even when using state-of-the-art machine learning techniques for time series forecasting, such as Long Short-Term Memory (LSTM) netwo

Abstract (sommario):
A enorme e rápida adesão ao uso das redes sociais, leva-nos a inferir que representam um dos mais relevantes fenómenos ligados à internet e às Tecnologias de Informação e Comunicação (TIC) em geral. Na generalidade dos casos, sempre que um comportamento assenta num rápido “crescimento”, um conjunto de questões serão levantadas. As redes sociais federadas surgiram no seguimento deste fenómeno, procurando colmatar algumas das lacunas identificadas nas redes sociais atuais, nomeadamente ao nível da portabilidade dos dados, da identidade, da referenciação e da privacidade. Após uma análise cuidada

Abstract (sommario):
<div>Federated learning (FL) is a decentralized privacy-preserving learning technique in which clients learn a joint collaborative model through a central aggregator without sharing their data. In this setting, all clients learn a single common predictor (FedAvg), which does not generalize well on each client's local data due to the statistical data heterogeneity among clients. In this paper, we address this problem with PersFL, a discrete two-stage personalized learning algorithm. In the first stage, PersFL finds the optimal teacher model of each client during the FL training phase. In the se

Abstract (sommario):
The term Softwarized Networking encapsulates technologies that allow the use of software to program a communication network. These technologies, predominantly Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), have dominated the scientific interests of the networking community in the last decade. Leading companies already adopted SDN in large-scale deployments (e.g., Google’s B4 Project, Microsoft Azure). According to Cisco, 76% of all data centers will apply SDN by 2021. Along with a hand full of valuable advantages, the foundation of the success of Softwarized Ne

碩士<br>育達科技大學<br>資訊管理所<br>106<br>In recent years, unmanned aerial photographing of flying robots has become increasingly popular, and accidents have occurred due to improper operation of personnel, and even shooting in military forbidden areas has been heard. In view of this, the government revised the relevant laws to regulate the prohibition of over flight. When enforcing the law, the current policy must be reported by the public or patrolled by relevant law enforcement agencies personnel to the relevant locations.

Abstract (sommario):
Research Doctorate - Doctor of Philosophy (PhD)<br>Next-generation wireless communication systems are expected to deliver extreme improvements in throughput and energy efficiency, in an era of pervasive machine learning applications. Meeting the ambitious technical objectives set out in beyond-5G visions requires a collaborative effort among a large number of wireless access points. Leveraging advances in optimisation theory, this thesis studies collaborative radio resource management for the two most promising cloud-based wireless network architectures: Cloud Radio Access Networks (C-RANs) an
