摘要:

本文对整个物联网-雾-云架构进行建模,通过混合线性规划(MILP)优化服务放置问题,并联合最小化处理和网络的总功耗。研究了物联网服务放置的四个方面:1)不可拆分的服务,2)可拆分的服务,3)子服务同步的服务间处理开销和4)专用云数据中心(SP-DC)的部署。结果表明,对于容量受限的问题,与通用数据中心(GP-DC)中处理不可拆分服务的46%相比,服务拆分可节省高达86%的功耗。此外,据观察,子服务间的处理开销有很大的影响,服务分裂的总数。无论处理开销的比率多么微不足道,结果表明这不是一个微不足道的问题,因此需要对这一领域给予更多关注,以便最好地利用网络边缘的可用资源。此外,优化结果表明,对于非常高的需求,SP-DC可以实现高达50%的功率节省,而GP-DC则为30%。

英文摘要:

In this paper, the entire IoT-fog-cloud architecture is modelled, the service placement problem is optimized through Mixed Integer Linear Programming (MILP) and the total power consumption is jointly minimized for processing and networking. Four aspects of IoT service placements are examined: 1) non-splittable services, 2) splittable services, 3) inter-service processing overhead for sub-service synchronization and 4) deployment of special-purpose cloud data centers (SP-DCs). The results showed that for a capacitated problem, service splitting introduces power consumption savings of up to 86% compared to 46% with non-splittable services in relation to processing in general-purpose data centers (GP-DCs). Moreover, it is observed that the inter sub-service processing overhead has a great influence on the total number of service splits. However much insignificant the ratio of the processing overhead, the results showed that this is not a trivial matter and hence much attention needs to paid to this area in order to make the best use of the resources that are available in the edge of the network. Moreover, the optimization results showed that, for very high demands, power savings of up to 50% could be achieved with SP-DCs compared to 30% with GP-DCs.
