PERVCOMPRA-SE: A Pervasive Computing Reference Architecture from a Software Engineering Perspective

Abstract

Pervasive Computing is a very challenging and complex domain that still lacks a comprehensive unified architecture. In this paper, we propose a reference architecture for pervasive computing that captures most, if not all, of the key challenges and provides a new architecture model that can be used in almost any business context. It provides conceptual views for the smart environment (SE), the smart object (SO), and the pervasive system (PS). We evaluated the model using a simulation prototype to predict its reliability at runtime.

A Simulation Approach to Predicate the Reliability of a Pervasive Software System

“…However, their approach requires deep knowledge about the components' design during the design phase. In our approach we ran the experiments based on the technical specifications of the sensors and also on statistics gathered and produced by earlier researchers as well as our scientific calculations for the complexity of the modules as explained in [3]. We executed different scenarios in order to provide a prediction model with a high degree of confidence ( Fig.…”

“…It is derived from the structure of the baseline architecture model as introduced in the original research work [3]. The model is composed of Entities classified as part objects, resident objects, and visitor objects.…”

“…The main building modules of the simulation project are derived from the baseline architecture as specified in [3]. In addition, we added more modules to make the prototype more controllable and fulfilling for the simulation example as well.…”

“…The simulation model generates new join requests from smart objects as shown in equation/algorithm (3) [3]. We assume an average of 6 visits at a time and σ = 3.…”

“…We used both qualitative and quantitative methods to evaluate the reference architecture. Moreover, we implemented a simulation prototype to realize the baseline architectural model for pervasive systems [3].…”
