A Graph-Based Approach for Contextual Service Loading in Pervasive Environments

Abstract: Abstract. The pervasive computing paradigm promises great abilities whenever and wherever a user goes. However, as people are shifting from the desktop to more resource-constrained devices, issues due to scarce resources may appear preventing from the use of the available services and applications. In this paper, we consider the adaptive deployment as a mainstream solution to suit service-oriented applications to different context constraints such as the users requirements, the hosts resources, the services pr… Show more

“…When executing an application over a device, it can happen that the device has no more resources to execute all the services of the application, this middleware can dynamically decide which service to unload from the application, and when the resources are available to upload the service. The approach is done spontaneously, without the user intervention and is based on a graph colouring techniques [2]. • Spontaneous substitution [11]: transparent substitution between services depending on QoS properties.…”

“…First because "suitable" is defined according to the operational specifications, e.g., performance, security, availability, energy efficiency. Secondly, because to process large sets, planners are usually based on Artificial Intelligent (AI) techniques: graphs colouring [10], evolution algorithms [1], constraint solvers [8,5]. These planners consider the deployment of constrained components on various environments: network [8], datacenter [2], embedded systems [14] or even pervasive environments [12].…”
