Context-Based Resource Management and Orchestration in 5G Wireless Access Networks

Call for Papers

To handle the explosion of mobile devices and corresponding service demands, future 5G wireless access networks must implement technologies to deliver reliability and high peak data-rates at low latency. This is pushing infrastructure providers to devise new network architectures to efficiently augment the wireless access network capacity. The example of Heterogeneous Networks (HetNets) is a promising approach, in which the capacity boost is given by the large deployment of femto/small-cells into macro cells’ service areas. In order to fully unleash the potential of these dense networks, an architectural and technological redesign of the radio access network (RAN) is required. This automatically captures the novel concepts of network virtualization and programmability, such as Network Function Virtualization (NFV), network slicing, Software-Defined Wireless Networks (SDWN) techniques, control/user-plane functional split, and cloud-RAN solutions. These solutions would enable not only the pursuit of user throughput maximization, but also the flexibility to finely tailor the network to customers’ service requirements.

However, the performance improvement achieved with reconfigurability and flexibility features entails an increased management complexity. As a consequence, the overall network efficiency might be significantly impaired even when smart resource management algorithms are implemented. Therefore, contextual information, such as user profiles, user positions, application quality requirements, expected quality of experience, network status, and traffic prediction, becomes crucial, much more than in legacy networks, when dealing with network orchestration solutions based on flexible architectures.

This special issue aims to collect architectural proposals, theoretical studies, and experimental activities that demonstrate how contextual information can be used to improve the performance of the (virtualized) resource management and orchestration in 5G wireless access networks. The goal is to report on the most up-to-date contributions in the area, shedding the light on the most valuable context sources, accuracy levels required for taking advantage of contextual information, and technical solutions to anticipate the traffic evolution by means of contextual information. Technical aspects of contextual information exploitation must be central to all topics.

Potential topics include but are not limited to the following:

  • Context-based directional millimeter wave communications
  • Context-based 5G wireless association and adaptive resource allocation
  • Context-based cloud-RAN management
  • Predictive approaches for context-based 5G wireless access
  • Context-based radio access network slicing
  • Impact of the context on NFV solutions, for example, function migration (proactive or reactive) and functional placement
  • Role of the context in 5G network architecture design
  • Mobile Edge Computing (MEC) operations based on contextual information
  • Frameworks for context gathering and management in wireless networks
  • Contextual information in the standardization bodies of 5G Wireless Access Networks
  • Contextual information models and accuracy estimation in 5G Wireless Access Networks
