Three researchers from Luxembourg University have been awarded during the 32nd IEEE International Conference on Information Networking (ICOIN) which took place on 11 January 2018 in Thailand. Abdallah Ibrahim, Dr. Sébastien Varrette and Prof. Pascal Bouvry have awarded the prestigious “Best Paper Award” for their paper entitled “PRESENCE: Toward a Novel Approach for Performance Evaluation of Mobile Cloud SaaS Web Services”. The paper was selected from some 476 papers submitted to the conference and 196 selected to be presented during ICOIN’s technical sessions. 

ICOIN is an international renowned conference which gathers researchers and engineers from all over the world to discuss on recent advances in the areas of computer communication and networking technologies. On this occasion, PhD student Abdallah Ibrahim, Research Associate Dr. Sébastien Varrette and Professor Pascal Bouvry from the Computer Science and Communications Research Unit (CSC) have presented an innovative tool “PRESENCE” to better evaluate Cloud Services Providers (CSPs).

Abdallah Ibrahim explains in details the research project:  

Why did you develop such a tool?

“Cloud Services Providers (CSPs) deliver cloud services to cloud customers on a pay-per-use model. The quality of the provided services is defined using Service Level Agreements (SLAs). The recent developments in edge computing and the advent of mobile cloud computing platforms contribute to the success of this approach and the multiplication of offers. Unfortunately, despite the projections foreseeing a growing market for the coming years, there is no standard mechanism which exists to verify and assure that delivered services satisfy the signed SLA agreement. Accurate measures of the provided Quality of Service (QoS) is also missing most of the time.”

What is “PRESENCE” about?

“We aim at offering an automatic framework named PRESENCE, to evaluate the QoS and SLA compliance of Web Services (WSs) offered across several CSPs. PRESENCE aims at quantifying in a fair and by stealth way the performance and scalability of the delivered WS. By stealthiness, we refer to the capacity of evaluating a given cloud service by orchestrating multiple workload patterns that make them indistinguishable from a regular user traffic from the provider point of view. PRESENCE defines a set of Common performance metrics handled by a set of agents within a customized client (called the Auditor) for measuring the behaviour of cloud applications on top of a given CSP.”

What does this award mean to you?

"This paper opens novel perspectives for assessing the SLA compliance of Cloud providers using the PRESENCE framework. This award is a unique achievement in my academic career. It pushes me, keeps me energized and charges me up to take more challenges in my career. The motivation to continue working on PRESENCE framework has increased because it was proven that we are on the right track. This award is the reward for the hard work we all put in together in our team. We will now continue to work with the PRESENCE framework to finalize the stealth model in testing CSPs’ web services. Then, we will go further for testing real providers e.g. Amazon and Microsoft to validate our framework."

Note: ICOIN (http://icoin.org) is a prestigious conference sponsored by the IEEE Computer Society. It is one of the oldest forum for the presentation of technological advances and research results in the fields of theoretical, experimental, and industrial communications and information networks. ICOIN 2018 is the 32nd in the series that has been held annually since 1986. It brings together leading engineers and scientists in communication systems, cloud computing and networking from around the world. Research frontiers in fields ranging from grid computing to evolving cloud and edge (fog) computing are regularly advanced by results first reported in ICOIN technical sessions.
