With the large-scale deployment of cloud datacenters, high energy consumption and serious service level agreement (SLA) violations in datacenters have become an increasingly urgent problem to be addressed. Implementing effective virtual machine (VM) consolidation methods is great significance reduce SLA violations. The VM a well-known NP-hard problem. Meanwhile, efficient should consider multiple factors synthetically, including quality service, consumption, migration overhead, which...
Collaborative cloud-edge-end computing is a promising solution to support computation-intensive and latency-sensitive tasks by utilizing rich resources of cloud datacenters low access delay mobile edge (MEC) servers. Compared with traditional MEC, the cloud-edge environment has stronger heterogeneity servers networks, resulting in significant differences between computation speed delay. However, few studies on task offloading focused characteristic 5G heterogeneous networks environment. In...
The use of flying platforms such as unmanned aerial vehicles (UAVs), popularly known drones, is rapidly growing. UAVs can greatly support data collecting and processing for Internet Things devices (IoTDs) in mobile edge computing (MEC) systems due to their advantages high environmental flexibility. This paper focuses on the scenario where multiple heterogeneous rotary-wing complete collection missions cooperatively. introduces an energy minimization problem UAV-assisted MEC system which...
Abstract Mobility is a fundamental feature of mobile edge computing. Due to the mobility users, contextual attributes cloudlets such as server resources and network state will dynamically change with time during offloading, showing time-varying fuzzy characteristics. To this end, how make efficient offloading decision provide low-latency, low-power highly reliable services in MEC has become critical issue. In paper, we propose context-aware cloudlet algorithm based on neutrosophic set,...
In recent years, since edge computing has improved the performance of transportation systems, research on edge-computing-enabled systems received widespread attention. However, most previous studies overlooked that task requests in are unevenly distributed time and space, which easily causes overloading servers, resulting high response latency. To this end, we present a novel offloading scheme based graph neural network (GNN) deep reinforcement learning (DRL) (TransEdge). Specifically, first...
Recently, the Industrial Internet of Things (IIoT) has shown great application value in environmental monitoring. However, it suffers from serious bottlenecks energy and computing capability. To address them, researchers have made lots effort. Nevertheless, they neglect either edge–end collaboration or impact task queue backlog, resulting low system revenue. this end, we design a queue-aware computation offloading method based on DRL (QDRL). Specifically, represent long-term operation as...

Replication technology is a very important data management in cloud storage. Traditional replication control methods cannot usefully solve the load imbalance caused by hotspot access. This paper proposed dynamic algorithm based on access popularity called APDRA. Replicas were created and deleted dynamically according to of data, situation system nodes, effectively solving problem local overload hot spot recovery idle replicas. In end, superiority APDRA was verified experiment.
With the number of connected devices increasing rapidly, access latency issue increases drastically in edge cloud environment. Massive low time-constrained and data-intensive mobile applications require efficient replication strategies to decrease retrieval time. However, determination replicas is not reasonable many previous works, which incurs high response delay. To this end, a correlation-aware replica prefetching (CRP) strategy based on file correlation principle proposed, can prefetch...
