چکیده
Multi-access Edge Computing (MEC) facilitates the deployment of critical applications with stringent QoS requirements, latency in particular. This article considers problem jointly planning availability computational resources at edge, slicing mobile network and edge computation resources, routing heterogeneous traffic types to various slices. These aspects are intertwined must be addressed together provide desired all users still keeping costs under control. We formulate our as a mixed-integer nonlinear program (MINLP) we define heuristic, named Neighbor Exploration Sequential Fixing (NESF), facilitate solution problem. The approach allows operators fine tune operation cost total experienced by users. evaluate performance proposed model heuristic against two natural greedy approaches. show impact variation considered parameters (viz., different traffic, tolerable latency, topology bandwidth, link capacity) on defined model. Numerical results demonstrate that NESF is very effective, achieving near-optimal resource allocation solutions short computing time even for large-scale scenarios.

Joint Computation and Communication Cooperation for Mobile Edge Computing
This paper proposes a novel joint computation and communication cooperation approach in mobile edge computing (MEC) systems, which enables user cooperation in both computation and communication for improving the MEC performance. In particular, we consider a basic three-node MEC system that consists of a user node, a helper node, and an access point (AP) node attached with an MEC server. We focu...

متن کاملMobile Edge Computing: Survey and Research Outlook
Driven by the visions of Internet of Things and 5G communications, recent years have seen a paradigm shift in mobile computing, from the centralized Mobile Cloud Computing towards Mobile Edge Computing (MEC). The main feature of MEC is to push mobile computing, network control and storage to the network edges (e.g., base stations and access points) so as to enable computation-intensive and late...
