“…The authors presented the simulation, assessments, and critical analysis in various categories. Alessandro Testa et al 75 have proposed an approach to analyze the effect of undesired events over reliability constraint. Effect of this type of event must be identified before the development and deployment of applications.…”

Wireless sensor networks form the crux of a wide range of automated applications that are gaining popularity with every passing day. The journey of wireless sensor networks has seen simple sensory monitoring to sensing-processing-actuation based end-to-end applications to the design and deployment of highly sophisticated service-oriented use cases. This highly disruptive field has seen rapid transformations to gain insights and assess the relative merits. Demerits of competing design strategies, it very important to know the evolutionary milestones this technology has undergone in achieving the state-of-the-art in this area. In this article, a systematic review is carried out that captures the evolution of architectural designs and developments in wireless sensor network–based applications. This review delves into the relative pros and cons of various epochs in developments and delineates the future areas of research in wireless sensor network design paradigm.

“…Heuristics are strategies derived from previous experiences with similar problems. These strategies rely on using readily accessible, though loosely applicable, information to control problem-solving in human beings, machines, and abstract issues (Ippoliti, 2015;Şahin, Duran, Yakıcı, & Şahin, 2018;Testa, Cinque, Coronato, De Pietro, & Augusto, 2015). In BPM, redesign heuristics exist as a method that builds upon an extensive set of redesign options (Reijers & Liman Mansar, 2005).…”

The Emergency Departments (ED) of hospitals are poised for continuous improvement due to increasing demand. The ED are places where the efficiency of the services provided can save lives and therefore it should be seen as an area of maximum interest for process optimisation. This research aims at verifying if the application of Business Process Management (BPM) heuristics positively impacts the length of stay (LoS), without deteriorating the quality of the service provided. The methodology that underlies this research is a case study carried out in the ED of a public hospital. The data was gathered from individual interviews, focus groups, direct observation and document analysis. The BPM life cycle stages were followed. In addition, a simulation tool was used, and heuristics were chosen based on Devil’s Quadrangle theory. Three scenarios of the ED were considered. Additionally, three heuristics and any combination of them were also considered. Results show that heuristics positively impact the time variable without affecting the quality of the service, resulting in value gains for the patient. In terms of time consumption, the average LoS in the process was reduced by 22.5%, 15.9%, and 20.9% for each of the considered scenarios, while the maximum LoS was reduced by 29.2%, 36.2% % and 37.4%. Implications from these results were analysed. The novelty of this research is supported by the absence of studies applying BPM heuristics to ED. This research is a step forward to ally BPM heuristics and ED processes.

A Trust-Based Formal Model for Fault Detection in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are prone to failures and malicious attacks. Trust evaluation is becoming a new method for fault detection in WSNs. In our previous work, a comprehensive trust model based on multi-factors was introduced for fault detection. This model was validated by simulating. However, it needs to be redeployed when adjustment to network parameters is made. To address the redeployment issue, we propose a Trust-based Formal Model (TFM) that can describe the fault detection process and check faults without simulating and running a WSN. This model derives from Petri nets with the characteristics of time, weight, and threshold. Basic structures of TFM are presented with which compound structures for general purposes can be built. The transition firing and marking updating rules are both defined for further system analysis. An efficient TFM analysis algorithm is developed for structured detection models. When trust factor values, firing time, weights, and thresholds are loaded, precise assessment of the node can be obtained. Finally, we implement TFM with the Generic Modeling Environment (GME). With an example, we illustrate that TFM can efficiently describe the fault detection process and specify faults in advance for WSNs.
