the rapid expansion of the Internet of things (IoT) poses challenges to certain applications, such as Digital Twin (DT). While data from user devices can be filtered by human intelligence, this is not feasible for IoT devices. Owing to the voluminous data generated by IoT devices that require transmission and computing, traditional cloud computing architectures may no longer guarantee the Quality of Experience (QoE), even causing network congestion. To address this issue, we propose a novel Cloud-Network-Edge-Terminal (CNET) model, which includes an intelligent edge layer for filtering IoT data. the computing paradigm shift indicates that the network will provide services at the edge rather than in the cloud, which is so-called service localization. To demonstrate the benefits of service localization, we use integrated user requirement descriptions to measure QoE, specifically the concepts of Service Requirement Zone (SRZ) and User Satisfaction Ratio (USR). Additionally, we conduct extensive numerical simulations to evaluate the model's performance under varying Degrees of Localization (DoL). Our results show that service localization can significantly improve USR even in changing network conditions.

Geo-distributed (GD) training is a machine-learning technique that uses geographically distributed data for model training. Like Federated Learning, geo-distributed machine learning can provide data privacy and also benefit from the cloud infrastructure provided by many vendors in multiple geographies. However, GD training suffers from multiple challenges such as performance degradation due to cross-geography low network bandwidth and high cost of deployment. Additionally, all major cloud vendors such as Amazon AWS, Microsoft Azure, and Google Cloud Platform provide services in several geographies. Hence, finding a high-performance as well as cost-effective cloud service provider and service for GD training is a challenge. In this paper, we present our evaluation of the performance and cost associated with training models in multi-cloud and multi-geography. We evaluate multiple deployment architectures using computing and storage services from multiple cloud vendors. the use of serverless instances in conjunction with virtual machines for model training is evaluated in this study. Additionally, we build and evaluate cost models for estimating the cost of distributed training of models in a multi-cloud environment. Our study shows that the judicious selection of cloud services and architecture might result in cost and performance gains.

Withthe increasing penetration of renewable sources, distributed Energy Resources (DER) are emerging as a crucial components of modern power systems. In a distribution system integrated withdistributed Generation systems (DG's), efficient power management is crucial to minimize energy losses and maximize effective utilization of electrical energy. the power losses in distribution system have been on higher side due to low X/R ratio and high AT&C losses. this paper presents the minimization of power losses in a radial distribution system integrated with DG's. the load flow analysis is carried out using Forward-Backward Sweep (FBS) method. the optimal power levels of DG's for power loss reduction are obtained by using Particle Swarm Optimization (PSO) algorithm. the proposed method is efficient on a standard IEEE 15 bus radial distribution system.

We propose using a hierarchical retail market structure to alert and dispatch resources to mitigate cyber-physical attacks on a distribution grid. We simulate attacks where a number of generation nodes in a distribution grid are attacked. We show that the market is able to successfully meet the shortfall between demand and supply by utilizing the flexibility of remaining resources while minimizing any extra power that needs to be imported from the main transmission grid. this includes utilizing upward flexibility or reserves of remaining online generators and some curtailment or shifting of flexible loads, which results in higher costs. Using price signals and market-based coordination, the grid operator can achieve its objectives without direct control over distributed energy resources and is able to accurately compensate prosumers for the grid support they provide.

the protein-I project is a cross Ireland initiative that takes a food systems approach to enhancing the sustainability of protein production across the island of Ireland, as part of the protein-I project, this study aims to produce a smart agricultural supply chain solution. there is a need for the requirements of the system to be tailored for the specific use case, agriculture on the island of Ireland is different from agriculture in other parts of the world. the average size of a farm in the Republic of Ireland is 32.4 ha [8], compare this to Australia where the average is 4,331 ha [7], therefore farm practices in Australia will be different. To develop a solution that is catered to the needs of the Agri-food sector on the island of Ireland this study gathered requirements from a series of workshops and interviews with stakeholders. Several use cases were presented by the stakeholders to identify the deficiencies in the current supply chain, and to address these challenges, a custom solution has been designed and implemented.

Cloud and Fog computing are complementary technologies used for complex Internet of things (IoT) based deployment of applications. With an increase in the number of internetconnected devices, the volume of data generated and processed at higher speeds has increased substantially. Serving a large amount of data and workloads for predictive decisions in real-time using fog computing without Service-Level Objective (SLO) violation is a challenge. Integration of multiple cloud services and platforms with fog computing can resolve this issue by providing additional resources. In this work, we present a general-purpose System for Inference Request Management (SIRM) aimed at automatically generating a suitable execution workflow to execute ML/DL inference requests using fog with Function-as-a-Service (FaaS) and Machine Learning-as-a-service (MLaaS) offered by cloud vendors. Generated workflow minimizes the cost of deployment as well as SLO violations. the use of SIRM results in less than 5% violations when tested using health domain and recommender system based applications.
