Satellite edge computing (SEC) has emerged as a promising technology to deliver network services remote users. Coupled with software-defined networking (SDN) and function virtualization (NFV), SEC can provide flexibility, agility, efficiency when allocating storage resources. However, there still remain number of technical challenges in terms fairness the allocation physical resources service provisioning, especially satellite limited dynamic traffic demands. In this paper, we investigate...

Fog computing has rapidly become a widely accepted paradigm to mitigate cloud computing-based infrastructure limitations such as scarcity of bandwidth, large latency, security, and privacy issues. resources applications dynamically vary at run-time, they are highly distributed, mobile, appear-disappear any time over the internet. Therefore, ensure quality service experience for end-users, it is necessary comply with comprehensive monitoring approach. However, volatility dynamism...

<p>Satellite Edge Computing (SEC) is seen as a promising solution for deploying network functions in orbit to provide ubiquitous services with low latency and bandwidth support mission-critical applications. Software Defined Networks (SDN) Network Function Virtualization (NFV) enable SEC manage deploy more flexibly. In this paper, we study dynamic topology-aware VNF mapping scheduling strategy an SDN/NVF-enabled infrastructure maximize fairness terms of end-to-end service delay...
