Designing Modeling Tool for Embedded Systems and Sensor Networks

Abstract

With the complexity of developing the Embedded Systems, modeling them before their construction is very essential. Hence, modeling tools are increasingly being used as the primary development environment for creating, designing and simulating Embedded Systems. Sensor Networks also posses real time constraints modeling Sensor Networks is essential before implementation. A survey has been conducted on various open source modeling tools and their features are highlighted. Approach adopted for nding suitable modeling tool is to deal with nding essential features for the designing Embedded Systems and Sensor Networks and comparing them with features provided by di erent modeling tools.Tables showing comparison for di erent tools are presented in chapter 2.After analysis it was found that Ptolemy is one of the best available open source modeling tool for designing Embedded Systems.Also Ptolemy provides various tools including Sensor Networks development. Prototyping an embedded system with Ptolemy ful ls all the essential requirements for designing an Embedded Systems and Sensor Networks.Old Age Assistive Device is taken as reference case study to enhance Ptolemy as Ptolemy is open source modeling tool.Architecture study of Ptolemy is done for inclusion of components in to Ptolemy library. Old Age Assistive Device is simulated in Ptolemy to nd out missing features with Ptolemy. Library of sensors for Old Age Assistive Device are added to Ptolemy user library so the similar types of systems can be implemented in future without any major efforts. Thus, the purpose of designing modeling tool is served. Old Age Assistive Device is implemented on hardware using model based approach adopted in Ptolemy. Thus, Modeling reduces designing time of any embedded system and also give proof of concept at much earlier stage reducing errors at later stage.
