Mobile Cloud Computing in 3G Cellular Networks Using Pipelined Tasks [chapter]

Marvin Ferber, Thomas Rauber
2012 Lecture Notes in Computer Science  
Network latency is often high on mobile devices due to wireless access, e. g., via 3G cellular networks. To better use the ubiquitously available 3G network connections, we propose a pipelining task concept on a single encrypted channel between a mobile device and a cloud resource. This does not only increases wireless bandwidth occupation, it also makes wireless communication more predictable by assuring a high throughput even for small messages. Constantly high throughput allows for a better

In an experimental evaluation using streaming image processing, we investigate the performance and applicability of our approach and compare it to the widely used HTTP.

BPEL Remote Objects: Integrating BPEL Processes into Object-Oriented Applications

Marvin Ferber, Thomas Rauber, Sascha Hunold
2010 2010 IEEE International Conference on Services Computing  
Service-orientation and object-oriented design are common practice in the field of business application development. Business process execution languages help to facilitate the orchestration of Web services in service-oriented architectures (SOA). However, using business processes from within object-oriented and event-driven applications is difficult as asynchronous event handling is missing in workflow-based business process modeling languages. The present article presents an approach for
more » ... rating BPEL business processes into object-oriented applications. We propose BPEL remote objects (BPELROs) that can be accessed asynchronously in an object-oriented manner. We present a method how state-based business processes can be implemented using BPELROs. It is shown how to apply BPELROs for software modernization tasks and we also evaluate the performance of BPELROs on different BPEL engines.

Resource Allocation for Cloud-Assisted Mobile Applications

Marvin Ferber, Thomas Rauber, Mario Henrique Cruz Torres, Tom Holvoet
2012 2012 IEEE Fifth International Conference on Cloud Computing  
Mobile devices such as netbooks, smart phones, and tablets have made computing ubiquitous. However, such battery powered devices often have limited computing power for the benefit of an extended runtime. Nevertheless, despite the reduced processing power, users expect to perform the same types of operations as they could do using their desktop or laptop computers. We address mobile devices's lack of computing power by leveraging cloud computing resources. We present a middleware that relocates
more » ... omputingintensive parts of Java applications to cloud resources. Consequently, our middleware enables the execution of computing-intensive applications on mobile devices. We present a case study on which we adapt Sunflow, an open-source ray tracing application, to use our middleware and show the results obtained by deploying it on Amazon EC2. We show, via simulations, a cost analysis of using the different resource allocation strategies available on our solution.

Combining Object-Oriented Design and SOA with Remote Objects over Web Services

Marvin Ferber, Thomas Rauber, Sascha Hunold
2010 2010 Eighth IEEE European Conference on Web Services  
Current approaches of accessing stateful resources via SOAP Web services do not provide a standardized way to use program objects (classes). In this article, we show how the interface of an objectoriented class can be expressed using WSDL. This approach enables a program object to be used in a distributed environment by accessing its Web service interface. The set of Web services associated with a class define a Remote Object over Web Service (ROWS). A ROWS object can be used to facilitate the
more » ... imultaneous use of the concepts of Service Oriented Architectures (SOA) and Distributed Object Architectures (DOA). In this context, we show how ROWS objects can be utilized in BPEL. Beyond that, we present a ROWS implementation that is suitable to serve as a standalone distributed object middleware. In a case study, we show how classes that were written in Java can be made accessible remotely through the ROWS technology.

Load Balancing Concurrent BPEL Processes by Dynamic Selection of Web Service Endpoints

Marvin Ferber, Sascha Hunold, Thomas Rauber
2009 2009 International Conference on Parallel Processing Workshops  
Business workflows implemented as BPEL processes play an important role for many business applications. BPEL is used to orchestrate a series of Web service calls. Which provider is used for a specific Web service request is statically defined as endpoint of a Web service call within the BPEL code. If a Web service is offered by more than one provider an intelligent choice of a Web service provider can improve the throughput of a BPEL engine. In this article we study how a scheduling mechanism

The scheduling mechanism helps the BPEL engine to select between different Web service providers, e. g., according to their current workload. Three different strategies for scheduling Web service calls are examined in practical experiments, considering a homogeneous and a heterogeneous collection of Web service providers. We show that in most cases the dynamic scheduling approach leads to a smaller average execution time (makespan) of concurrently executed BPEL processes.

Reducing the Class Coupling of Legacy Code by a Metrics-Based Relocation of Class Members [chapter]

Marvin Ferber, Sascha Hunold, Björn Krellner, Thomas Rauber, Thomas Reichel, Gudula Rünger
2012 Lecture Notes in Computer Science  
With the rapid growth of the complexity of software systems, the problem of integrating and maintaining legacy software is more relevant than ever. To overcome this problem, many methods for refactoring legacy code have already been proposed such as renaming classes or extracting interfaces. To perform a real modularization, methods have to be moved between classes. However, moving a single method is often not possible due to code dependencies. In this article we present an approach to
more » ... e legacy software by moving multiple related class members. It is shown how to identify groups of class members with similar concerns. We present two different code patterns that the related members and their dependent classes must match to allow a relocation of the related members. We also demonstrate how our pattern-based approach for automated modularization of legacy software can be applied to two open source projects.
