“…Many researchers have used "Priority" as an important index for evaluating or choosing adaptation rules on research domains such as security, health care, management, etc. [22][23][24]. While Spicker proposes to use five priority levels (Lexical ordering, special status, precedence, relative value, and importance,) in choosing adaptation rules [25].…”

Recently, given the rise of emerging demands on intelligent technological systems, increasing attention has been given to proliferating and enhancing the adaptation capacities of self-adaptive systems (SAS), which are capable of adapting their behavior to changes in the context or system resources contributing to overcome the complexity of today’s software-intensive systems. However, there are a significant number of challenges for developing adaptations on the SAS, such as simplifying the designer’s task, improving responsiveness, and reducing the conflicts between its adaptations. This study focuses on simplifying the designers’ tasks by utilizing independent designers’ viewpoints on context modeling. We proposed several solutions for solving the conflicts among different viewpoints of designers in the layer of context-aware management (CAM). The validation results are promising and show that our method effectively provides a solution that supports the problem of using independent viewpoints in the context modeling process and improves the SAS adaptation capacity.

“…A context-aware adaptive application that modeled a system behavior using information derived from the context information was discussed in [19]. The goal-oriented approach used nonfunctional goals to analyze and select possible adaptation alternatives, in consideration of the particular contextual event.…”

In the Internet of Things (IoT) paradigm, context state information plays a critical role in advancing the development of adaptive pervasive applications. Pervasive services and context-aware computing are emerging as the next computing paradigms in which infrastructure and services are seamlessly available anywhere, anytime, and in any format. The IoT paradigm raises new opportunities and demands on the underlying systems, in particular, the need to have systems that are adaptive and context-aware using context state information. In this paper, we introduce a new adaptive context state design technique to model context-aware applications that are sensitive to context state information changes. Each context change event is captured, interpreted and reacted to so that applications and users use only the functionality and adaptability needs that are solutions to their needs. The solution is modeled using Finite State Machine (FSM) and semantic localization so that context state information within the IoT paradigm is aligned to events. The semantic localization process precisely estimates the proximity location of the user along with the quality of context (QoC) attributes using the Bluetooth cell-based approach. This semantic information is useful in determining and inferring the user activities in a location. The QoC attributes are used to determine the confidence of the user location and range of the Bluetooth beacons within the IoT domain. This will, in turn, be used to determine whether the user is in the location or not. The alignment technique in our model represents the proper and new solution concerning functionality and adaptability needs expressed by other user applications in the IoT environment. The experimental scenario results indicate that a user can continue to enjoy their daily activities while the IoT application adapts continuously to their changing needs and notifying service providers of the changes according to the events of the user.

“…Rule-based systems (Salber et al 1999;Dey 2001;Etter et al 2006;Wang et al 2011) have been in use for decades for both model representation and reasoning in context-aware applications. More recently, Nalepa and Bobek (2014) have proposed a rule-based, learning middleware for storage and reasoning in a distributed scenario.…”

Theory and Practice of Logic Programming

New generations of distributed systems are opening novel perspectives for logic programming (LP): on the one hand, service-oriented architectures represent nowadays the standard approach for distributed systems engineering; on the other hand, pervasive systems mandate for situated intelligence. In this paper we introduce the notion of Logic Programming as a Service (LPaaS) as a means to address the needs of pervasive intelligent systems through logic engines exploited as a distributed service. First we define the abstract architectural model by re-interpreting classical LP notions in the new context; then we elaborate on the nature of LP interpreted as a service by describing the basic LPaaS interface. Finally, we show how LPaaS works in practice by discussing its implementation in terms of distributed tuProlog engines, accounting for basic issues such as interoperability and configurability.
