Embedded systems are used in broad variety of areas. As increasing processingrnpower, being networked and having more multiple and complicated functionality, thernembedded systems used in control systems have more issues to be resolved. In many cases,rndesign constraints are applied to the entire life-cycle of the embedded systems. There arernstakeholders involved in the systems through the life-cycle and they play their roles in eachrnstage of the life-cycle. However, concerns of all of the stakeholders are less taken care of.rnChallenges to develop networked embedded systems for control systems are to maximize all ofrnthe stakeholders' satisfactions through the entire life-cycle in addition to satisfy severalrnconstraints. This paper discusses architectures of networked embedded systems from arnperspective of stakeholders’ satisfactions. We present the stakeholders and their standpoints,rncomposition of networked embedded systems and architectures, then pros and cons of thernarchitectures from each stakeholder’s view.
