AI总结:

本文通过仿真评估车载云计算(VCC)在城市环境中替代边缘计算(EC)支持低延迟应用的可行条件,并分析其相对成本优势。

摘要:

边缘计算(EC)是指在靠近用户的位置部署计算资源,从而支持增强现实和在线游戏等低延迟应用。然而,大规模部署边缘节点可能极不现实且成本高昂。除 EC 之外,还有一个正在兴起的概念,称为车载云计算(VCC)。VCC 是一种计算范式,它通过利用车辆的部分计算资源来增强车辆能力,使其能够参与类似于 EC 所提供的服务。VCC 的优势在于,它可以机会性地利用车辆上已经存在的部分计算资源,从而使网络运营商免于承担 EC 节点的部署和维护成本。然而,目前仍不清楚在哪些情况下 VCC 能够在没有 EC 的情况下支持低延迟应用。在本研究中,我们表明 VCC 有潜力在城市地区有效取代 EC,尤其是考虑到此类环境中车辆密度较高。本文的目标是通过仿真分析决定在何种条件下可以用 VCC 替代 EC 的关键参数。此外,我们提供了一项高层成本分析,以表明对网络运营商而言,VCC 的成本远低于采用 EC。

英文摘要:

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.
