Congestion-aware multiaccess edge computing collaboration model for 5G (original) (raw)

2020, International Journal of Communication Systems

In 5G cloud computing, the most notable and considered design issues are the energy efficiency and delay. The majority of the recent studies were dedicated to optimizing the delay issue by leveraging the edge computing concept, while other studies directed its efforts towards realizing a green cloud by minimizing the energy consumption in the cloud. Active queue management-based green cloud model (AGCM) as one of the recent green cloud models reduced the delay and energy consumption while maintaining a reliable throughput. Multiaccess edge computing (MEC) was established as a model for the edge computing concept and achieved remarkable enhancement to the delay issue. In this paper, we present a handoff scenario between the two cloud models, AGCM and MEC, to acquire the potential gain of such collaboration and investigate its impact on the cloud fundamental constraints; energy consumption, delay, and throughput. We examined our proposed model with simulation showing great enhancement for the delay, energy consumption, and throughput over either model when employed separately.

The essential services such as e-banking, e-health, and e-learning will continue to evolve into more mobile services, and the amount of on-demand content (information and entertainment) served over mobile and wireless communication systems will continue its growth. 1,2 Moreover, it is generally accepted by now that, in the future, a substantial number of wireless devices will be incorporated into today's dominating human-centric communication; this paradigm, recognized as the Internet of Things (IoT), will make our daily life more efficient, convenient, and secure. 3 IoT aims to unite a versatile and huge number of smart objects through the Internet to connect at any time with anything and anyone. The evolution of IoT will also inflict new requirements and challenges to
