A framework for multi-interfaced Service Level Agreements on mobile devices

Today, the service computing research is focusing on providing efficient solutions to the challenges of the future Internet applications. The major difference that is created by these applications is their ubiquitous on-the-move availability as cloud services. This means that the mobility is rapidly becoming a fundamental requirement of the future. In addition to that, the integration of mobile and service computing domains has enabled the existing mobile devices to offer their resources as mobile Web Services (WS). For this reason, the provisioning of mobile WS in future networks is expected to become a part of the cloud, where ubiquitous services are offered by any device. This will open new business prospects for the service providers. In this paper, we present the concept of protecting such mobile WS by using Service Level Agreements (SLA) on mobile devices. Here, we propose a framework to offer SLA negotiations and manage the Quality of Service (QoS) of the provisioned mobile WS. Furthermore, the paper explains the four primary architectural components and classifies their functions into four fundamental SLA life cycles. Also, the detailed discussion regarding each life cycle and its relation to the corresponding component(s) is provided. The research addresses some major issues of authentic and authorized access to mobile WS that might become useful as we move towards the future ubiquitous Internet.
