“…IoT applications should adapt their behaviour to changes in an extremely dynamic environment: users enter and exit from "smart environments" (e.g., smart homes [3][4][5], smart hospitals [6][7][8], smart offices [9,10], and tourism locations [11,12]), objects change their position according to specific application purposes (e.g., mobility of persons [13,14], multimodal transport of goods [15], and maritime surveillance [16]). Discovery mechanisms are thus required in order to obtain up-to-date information about functional capabilities offered by devices distributed in the environment or information repositories storing information about a given object.…”

Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users' quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of "smart things" on a large scale. It is widely recognized that efficient mechanisms for discovering available resources and capabilities are required to realize such vision. The contribution of this work consists in a novel discovery service for the Internet of Things. The proposed solution adopts a peer-to-peer approach for guaranteeing scalability, robustness, and easy maintenance of the overall system. While most existing peer-to-peer discovery services proposed for the IoT support solely exact match queries on a single attribute (i.e., the object identifier), our solution can handle multiattribute and range queries. We defined a layered approach by distinguishing three main aspects: multiattribute indexing, range query support, peer-to-peer routing. We chose to adopt an over-DHT indexing scheme to guarantee ease of design and implementation principles. We report on the implementation of a Proof of Concept in a dangerous goods monitoring scenario, and, finally, we discuss test results for structural properties and query performance evaluation.

“…Similarly, a heat sensor in the environment may serve as a data resource for a process in which temperature of the room should be kept in an acceptable range. Context is of capital importance since it helps dene and augment the tasks [21]. In addition, this enables that every task will be instantiated in its particular context, and so can be customized.…”

In daily life, people have to perform a large number of activities typically in a limited amount of time. Thus, they may need help and guidance provided by support systems in order to accomplish these activities accurately and in the correct order. Accordingly, in this study, we propose a software framework based on workows and supported by a mobile application to assist users in pervasive environments for managing their personal activities. Pervasive computing enables to ease and automate the execution of the activities by integrating user's context into management of activities. Therefore, the framework augments user activities with context information, and gives a broader and a customized meaning to them, so provides advanced assistance by using sensors and devices in the environment, making web service calls, and utilizing mobile phone features. Moreover, the relationship between activities and context resources enable to automate user's tasks by dening rules within the framework. In parallel with this information, a prototype implementation is developed, and tested with scenarios from various domains. Consequently, applicability of these scenarios indicates workableness and feasibility of this framework in pervasive environments.

“…Although the MDD technologies seem to produce promising results for standard service compositions, we may face various challenges when applying them in the CASC domain, since they do not consider contextual information while service compositions are developed or executed (Ibrahim, 2012). Some studies (Furno and Zimeo, 2014;Kocurova, 2013;Schefer-Wenzl and Strembeck, 2013) have used a proprietary solution, inconsistent with industry-accepted standards, making their acceptance a severe challenge. Several existing techniques (Cherif et al, 2016;Furno and Zimeo, 2014;Hagin, 2011) have also embedded contextual information into composite services.…”

The proliferation of smartphones and sensor-based networks has led to a greater need for contextaware applications and pervasive business processes. One of the key approaches that seek to satisfy this need is context-aware service composition. Service composition can be achieved in two ways, i.e., service choreography and service orchestration. Embedding the context into an orchestrated composite service enhances its flexibility, but makes its development and execution more complicated. This study aims to reduce this complexity by introducing the CA-BPEL approach. Our proposed approach enables developers to turn a standard orchestrated service into a context-aware orchestrated service, consistent with the standard WS-BPEL language. This study applies the Design Science Research Methodology, in which we evaluate CA-BPEL by using a tourism demonstration along with the conduction of a usability survey that shows the convenience of the proposed approach. We also compare our proposed approach with 14 related studies. Our investigations suggest that CA-BPEL has much potential to facilitate the development and execution of context-aware service compositions.
