为了适应急剧增长的流量需求，HetNet中的一些中间节点应该被赋予存储和计算能力，以促进普适计算服务和大规模内容交付。ICN和MEC被认为是两种很有前途的技术，利用它们可以在移动的设备附近缓存和计算内容。这些先进的技术使Het-Net能够容纳和支持更多的移动的用户，但也带来了架构部署和资源部署的挑战。沿着这些思路，本文的第一部分提供了一种新颖的基于无线网络虚拟化和软件定义网络的HetNet的通信，缓存和计算的联合架构，其中ICN和MEC相互支持，以提高网络性能，并保证不同类型的业务需求。基于综合框架，我们进一步提出了两种不同的自我执行机制（即，高速缓存辅助MEC方法和计算辅助ICN方法），以实现高速缓存和计算之间的相互促进。在此背景下，本文的第二部分提供了上行链路和下行链路场景的虚拟多资源部署，以评估通信、缓存和计算收入之间的三方权衡。结果表明，我们的假设，利用ICN和MEC之间的相互促进，以提高未来的无线系统的整体性能。
To accommodate the dramatically increasing traffic demand, some of the intermediate nodes within HetNets should be endowed with storage and computation capabilities for facilitating pervasive computation service and massive content delivery. ICN and MEC are recognized as two promising techniques, with which content can be cached and computed in close proximity to mobile devices. These advanced techniques enable Het- Nets to accommodate and support more mobile users, but also bring challenges of architecture deployment and resource deployment. Along these lines, the fist part of this article offers a novel joint architecture of communications, caching, and computing for HetNets based on wireless network virtualization with software defined networking, where ICN and MEC support each other to promote network performance and guarantee different types of business demands. Based on the integrated framework, we further present two different self-enforcing mechanisms (i.e., a caching-assisted MEC approach and a computing-assisted ICN approach) to achieve mutual promotion between caching and computing. Against this background, the second part of this article offers virtual multi-resource deployment for both uplink and downlink scenarios to evaluate a three-way trade-off among communication, caching, and computing revenues. The results demonstrate our hypothesis on the utilization of the mutual promotion between ICN and MEC to improve the overall performance of future wireless systems.
