标题： Can vehicular cloud replace edge computing?

摘要： 边缘计算（EC）包括将计算资源部署在用户附近，从而实现低延迟的应用程序，例如增强现实和在线游戏。 然而，边缘节点的大规模部署可能非常不切实际且成本高昂。 除了EC之外，还有一种新兴的概念被称为车载云计算（VCC）。 VCC是一种计算范式，通过利用部分车辆的计算资源来增强车辆的能力，使其能够参与类似于EC提供的服务。 VCC的优势在于它可以机会性地利用已经存在于车辆上的部分计算资源，从而减轻网络运营商部署和维护EC节点的成本。 然而，目前尚不清楚在何种情况下VCC可以在没有EC的情况下实现低延迟的应用程序。 在本工作中，我们表明，VCC在城市地区有潜力有效取代EC，尤其是在这种环境中车辆密度较高的情况下。 本文的目标是通过仿真分析确定这种由VCC取代EC的可行性条件的关键参数。 此外，我们提供了一个高层次的成本分析，以表明对于网络运营商而言，采用VCC要远比采用EC成本更低。 显示英文摘要

摘要： Edge computing (EC) consists of deploying computation resources close to the users, thus enabling low-latency applications, such as augmented reality and online gaming. However, large-scale deployment of edge nodes can be highly impractical and expensive. Besides EC, there is a rising concept known as Vehicular Cloud Computing (VCC). VCC is a computing paradigm that amplifies the capabilities of vehicles by exploiting part of their computational resources, enabling them to participate in services similar to those provided by the EC. The advantage of VCC is that it can opportunistically exploit part of the computation resources already present on vehicles, thus relieving a network operator from the deployment and maintenance cost of EC nodes. However, it is still unknown under which circumstances VCC can enable low-latency applications without EC. In this work, we show that VCC has the potential to effectively supplant EC in urban areas, especially given the higher density of vehicles in such environments. The goal of this paper is to analyze, via simulation, the key parameters determining the conditions under which this substitution of EC by VCC is feasible. In addition, we provide a high level cost analysis to show that VCC is much less costly for a network operator than adopting EC.
