The development of educational policies that improve educational systems needs intelligent automated tools for decision making. This need has motivated the development of a new system which can help teachers, schools, and decision makers in enhancing students' performance. The primary concern here is to monitor the students and help the teachers in building action plans that improve students' performance...
Automated identification and recovery of faults are important and challenging issues for service-oriented systems. The process requires monitoring the system’s behavior, determining when and why faults occur, and then applying fault prevention/recovery mechanisms to minimize the impact and/or recover from these faults. In this paper, we introduce an approach (defined FOLT) to automate the fault identification...
Business process automation using software as a service is well accepted software deployment and distribution model that is grown exponentially in the last few years. SaaS can provide solutions that are suitable for both one off as well as long running systems. Multiple component services are combined to formulate a composite solution. This modular nature of the systems allows the flexibility to replace...
Service Oriented Architectures (SOAs) enable the automatic creation of business applications from independently developed and deployed Web services. As Web services are inherently a priori unknown (in terms of dependability), how to deliver reliable Web services compositions is a significant and challenging problem. In this paper, we propose a framework for infusing dependability in SOAs through self-healing...
A modern organization's day to day operations rely heavily on the proper functioning of its IT systems. Increasingly, most of these systems are starting to be based on the Service Oriented Architectures (SOAs). SOAs enable the automatic creation of business applications from independently developed and deployable Web services. When a SOA component suffers failure it results in sub-par operational...
With the extensive adaptation of Web service based applications in dynamic businesses applications including on demand computing, highly configurable virtual solutions and cloud computing based systems demand automated tools for composing and managing these services in composite systems. The use of standard protocols for publishing, discovery, invocation, process definition and SLA definition etc...
Web services are a popular choice for component oriented systems that support dynamic compositions. Automated negotiation among Web services provides an effective way for the services to bargain for their optimal customizations and allows the discovery of overlooked potential solutions. Unique and dynamic Quality of Service (QoS) requirements of service consumers pose challenges for effective approaches...
Web services are a popular choice for component oriented systems. Web services not only provide a platform independent architecture but also support dynamic compositions to facilitate on the fly creation of composite solutions. Automated negotiation among Web services provides an effective way for the services to bargain for their optimal customizations and allows the discovery of overlooked potential...
Cloud computing enables the automated creation of business applications from independently developed and deployed services. In this paper, we propose a technique for Cloud-based services to dynamically evaluate the performance of services based on their previous history, and user requirements. The likelihood of fault occurrence is then used to create recovery plans. The ‘best’ recovery plan is then...
In this paper, we propose a technique for service-oriented architectures (SOA) to dynamically evaluate the performance of Web services based on their previous history, and user requirements. The likelihood of fault occurrence is then used to create recovery plans. The ‘best’ recovery plan is then chosen to be either executed immediately, or saved for a later execution. We assess the overall system...
Route discovery in manymobile ad hoc protocols is based on flooding. However, flooding suffers from high overhead, which can increase contention and communication delays. In this paper,we propose twonewroute discovery algorithms that are aimed towards reducing these delays. Both algorithms are suitable for use with ad hoc protocols where nodes periodically broadcast Hello Messages. Using the GloMoSim...
Automated negotiation among Web services not only provides an effective way for the services to bargain for their optimal customizations, but also allows the discovery of overlooked potential solutions. A number of negotiation supporting techniques have been used to find solutions that are acceptable to all parties in the negotiation. However, employing these solutions for automated negotiations among...
