Low-Power Wide-Area Networks (LPWAN) are a type of wireless communication technologies that enable efficient data transfer between low-power devices. This article explores the challenges of ensuring security in LPWANs and proposes a solution that combines two key mechanisms: Object Security for…

Network Function Virtualization (NFV) opens us great opportunities for network processing with higher resource efficiency and flexibility. In this respect, there is an increasing need for intelligent orchestration mechanisms, such that NFV can exploit its potential and live up to its promise.…

Network Function Virtualization (NFV) has paved the way for the migration of Virtual Network Functions (VNFs) into multi-tenant datacenters, lowering the barrier for the introduction of new processing functionality into the network. Recent trends for resource orchestration across the entire compute…

In-band network telemetry (INT), empowered by programmable dataplanes such as P4, comprises a viable approach to network monitoring and telemetry analysis. However, P4-INT as well as other existing frameworks for INT yield a substantial transmission overhead, which grows linearly with the number of…

Intent-driven orchestration enables organizations to achieve greater automation, integration, and intelligence of their compute and network resources by defining their objectives and policies in a more abstract and holistic way, while letting the orchestration system handle the coordination,…

With the rapid advancement in the next-generation Internet of Things (IoT) and the ever-expanding virtual representation of devices, novel techniques and definitions are key to accommodate emerging paradigms to transform our world. In the quest of achieving the coveted convergence of IoT…

(THIS PAPER RECEIVED THE BEST PAPER AWARD OF 2023 IEEE CLOUD). Over the last years, the ever-growing number of Machine Learning (ML) and Artificial Intelligence (AI) applications deployed in the Cloud has led to high demands on the computing resources required for efficient processing. Multiple…

Time-Sensitive Networking (TSN) aspires to provide a solid underpinning for meeting latency guarantees across traffic classes with diverse requirements. Despite the emergence of various specifications from the TSN family of standards, there is a shortage of prototype implementations with support…

This study considers a multi-tier heterogeneous DRAM/NVM memory system with contrasting access latency, bandwidth and energy consumption capabilities. The paper examines the implications of heterogeneous memory tiering on Spark in-memory analytics and addresses the challenge of the growing demand…

When a natural or human disaster occurs, time is critical and often of vital importance. Data from the incident area containing the information to guide search and rescue (SAR) operations and improve intervention effectiveness should be collected as quickly as possible and with the highest accuracy…
