摘要:

随着物联网的发展,在未来6G通信中,将会产生众多实时性应用场景。在低时延的数据处理需求的驱动下,移动边缘计算将成为提升用户体验和降低网络成本的重要技术。然而,单一的边缘服务器计算能力有限,很难满足计算密集型应用的低时延数据处理需求。设计了一种异构的多层边缘计算(HetMEC,heterogeneous multi-layer mobile edge computing)网络架构,综合利用云计算中心和多层边缘服务器的计算和传输资源,通过合理分割卸载计算任务,共同为边缘应用提供可靠、高效的计算服务。实验证明,HetMEC网络架构可以有效降低处理时延,提升网络处理速率和稳健性。

Abstract:

With the development of the Internet of things,multiple real-time applications will emerge in future 6G communication network.Driven by demands on low-latency services of multiple real-time applications,mobile edge computing (MEC) will become an important technology to improve the user experience and reduce the network cost.However,the computing capacity of a single MEC server is limited,which induces that it is difficult to meet the low-latency requirement of data processing for the computation-intensive applications.A heterogeneous multi-layer mobile edge computing (HetMEC) network architecture was proposed to jointly utilize the computing and transmission resources of both the cloud computing center and multi-layer MEC servers.By reasonably dividing and offloading computing tasks,reliable and efficient computing services were provided for edge applications.Simulation results show that the proposed algorithm could effectively reduce the processing latency,improve the network processing rate and robustness.

Key words: Internet of things, heterogeneous network, mobile edge computing, task assignment, resource allocation
