SDN-based IaaS for mobile computing
Wijaya Ekanayake, Heli Amarasinghe, Ahmed Karmouch · 2017
Mobile Cloud Computing enables resource limited mobile devices to support rich application services. Among three types of cloud services, Infrastructure-as-a-Service (IaaS) clouds provides compute infrastructure for mobile applications on demand. In IaaS-based mobile clouds, latency and bandwidth requirements can considered as critical factors impacting Quality of Service (QoS). Opposed to centralized clouds, geographically distributed clouds realize higher QoS benefiting the proximity to the end user. In this paper, we propose an IaaS framework with regional datacenters for mobile clouds. With the benefits of software-defined networking (SDN), we address impacts on QoS during mobility by serving mobile user via the optimum datacenter. A test-bed was developed to measure the performance of service allocation and relocation in proposed framework.
