Delivering Mobile Cloud Services to the User: Description, Discovery, and Consumption

Abstract

Access to the full text of the published version may require a subscription. However, these services are described by mark-up languages, such as XML, that cannot be comprehended by non-specialists. Furthermore, the lack of common interfaces for related services makes discovery and consumption difficult for both users and software. The problem of service description, discovery, and consumption for the mobile cloud must be addressed to allow users to benefit from these services on mobile devices. This paper introduces our work on a mobile cloud service discovery solution, which is utilised by our mobile cloud middleware, Context Aware Mobile Cloud Services (CAMCS). The aim of our approach is to remove complex mark-up languages from the description and discovery process. By means of the Cloud Personal Assistant (CPA) assigned to each user of CAMCS, relevant mobile cloud services can be discovered and consumed easily by the end user from the mobile device. We present the discovery process, the architecture of our own service registry, and service description structure. CAMCS allows services to be used from the mobile device through a user's CPA, by means of user defined tasks. We present the task model of the CPA enabled by our solution, including automatic tasks, which can perform work for the user without an explicit request. Rights

Context Aware Mobile Cloud Services: A User Experience Oriented Middleware for Mobile Cloud Computing

“…CAMCS provides two user task models for CPAs, which were described in a previous work [5]. The first is the userinitiated task; the user creates a task with a name and description using the CAMCS Client installed on his/her mobile device.…”

“…Such services are not suitable for direct human-consumption, as they are commonly described with XML-based technologies such as WSDL. CAMCS uses a custom user-oriented mobile cloud service description format for describing existing webbased services [5]. These feature user-friendly service descriptions, which allow the mobile user to take part in the service discovery process, to find a service that his/her CPA can use to complete a task.…”

Reliable Web Service Consumption Through Mobile Cloud Computing

“…Mobile cloud computing (MCC) is the combination of cloud computing, mobile computing, and wireless networking to bring rich computational resources to mobile users, network operators, as well as cloud computing providers. That enables the applications that could not run on the mobile device due to the mentioned constraints and can now be delivered to users of these devices [3].…”
