“…That is, based on the number of commit and abort transactions, an appropriate commit protocol is chosen for the processing of a transaction. However, the above approaches [10,11] are limited to the classical concurrency and commit protocols and do not take into account the context information such as location, time, and so on.

With the ubiquity of handheld devices (such as smart phones and PDAs) and the availability of a wide range of mobile services (such as mobile banking, road traffic updates, and weather forecast) people can nowadays access information and conduct online transactions virtually anywhere and anytime. In such flexible, dynamic but less reliable environment, transaction management technology is believed to provide service reliability and data consistency. Indeed, in mobile and ubiquitous environments where devices as well as services can, seamlessly join and leave the ubiquitous network, transaction management can be very helpful during the recovery of services from failure. Current transaction models and commit protocols do not take into account context information. However, in mobile environments it is imperative to consider context information in the commit of a transaction -i.e., a transaction can be successfully completed if it meets the required context. In this paper we propose a new model for context-aware transactions and their performance management in mobile environments. Unlike conventional transactions, context-aware transactions adapt to the required context. By context we mean the service context as well as the user's context that includes user's needs and preferences. This paper designs and develops the proposed transaction model and evaluates its performance in terms of time and message complexities as well as transaction's throughput.

“…Current middleware evaluations show that about half of the source code is related to the business concerns (measures observed on GoTM [27], Fractal Deployment Framework [12], and COSMOS [24] projects). This means that, thanks to the use of Fraclet, the application source code becomes less prone to errors, and gains in terms of visibility by removing the technical methods that were not related to the business concerns.…”

Component-based software engineering has achieved wide acceptance in the domain of software engineering by improving productivity, reusability and composition. This success has also encouraged the emergence of a plethora of component models. Nevertheless, even if the abstract models of most of lightweight component models are quite similar, their programming models can still differ a lot. This drawback limits the reuse and composition of components implemented using different programming models.The contribution of this article is to introduce Fraclet as a programming model common to several lightweight component models. This programming model is presented as an annotation framework, which allows the developer to annotate the program code with the elements of the abstract component model. Then, using a generative approach, the annotated program code is completed according to the programming model of the component model to be supported by the component runtime environment. This article shows that this annotation framework provides a significant simplification of the program code by removing all dependencies on the component model interfaces. These benefits are illustrated with the Fractal and OpenCOM component models.

“…To hide the complexity of service processes from users as much as possible, ubiquitous systems have to dynamically adapt to changing contexts and intelligently handle failures and recovery [6]. Therefore, the advanced transaction management is another key technology [2] to ensure the reliability of MUC in a transparent way.…”

Abstract-Transaction management for mobile and ubiquitous computing aims at providing mobile users with reliable services in a transparent way anytime anywhere. To make such a vision a reality, transaction processing for the mobile and ubiquitous computing needs to adapt to the runtime environments dynamically. However, most existing mobile transaction models do not consider the context-based transaction management. In this paper, we propose a context-aware transaction model and context-driven coordination algorithms. They are built on an event-contextaction mechanism, enabling the transaction processing to adapt well to dynamically changing transaction context. The simulation results have also demonstrated that our model and algorithms can significantly improve the successful commit ratio under unstable context conditions.
