Mobility Support and Network Selection in Ultradense Heterogeneous Networks for 5G and Beyond Communication Systems

Call for Papers

Seamless connectivity is one of the key issues to consider when integrating two or more different wireless technologies. The exponential growth of wireless connectivity necessitates the convergence of ultradense heterogeneous networks. This is due to the fact that a single network may not be able to provide the high quality of service (QoS) required for certain high data rate services, such as multimedia applications. Moreover, network densification is regarded as the leading driver for the evolution into the era of fifth generation (5G) communications, which further requires networks to be able to support high spectrum efficiency. Therefore, the convergence of ultradense heterogeneous networks is considered a key enabler for 5G and beyond communication systems.

However, the densification of wireless networks leads to reduced coverage areas for the associated networks. As a consequence, internetwork handover needs to be carefully considered. To this end, appropriate network architecture should be chosen in a multitier network, which may include a combination of diverse networks, such as optical wireless networks as well as radio frequency-based picocells, small cells, and macrocells. Future networks need to provide seamless connectivity while considering a wide variety of nodes, bandwidth requirements, and applications for low to high mobility users. Therefore, simplifying the network architecture while taking into account radio resource management for mobility support in ultradense heterogeneous networks is an important research issue that needs to be investigated during the implementation of 5G and beyond communication systems.

This special issue aims to receive high-quality papers that extend the current state of the art with innovative ideas and solutions in the broad area of resource management for mobility support and network selection in 5G and beyond communication systems. Contributions may present and solve open research problems, integrate efficient novel solutions, present performance evaluations, and compare new methods with existing solutions. Theoretical as well as experimental studies for typical and newly emerging convergence technologies and use cases enabled by recent advances are encouraged. High-quality review papers are also welcome.

Potential topics include but are not limited to the following:

  • Software-defined networking (SDN)-based mobility management
  • Resource-based mobility management
  • Network architecture for mobility support
  • Intelligent network selection in multitier networks
