Abstract: The context aware framework is the backbone of context aware application the framework. It is because the context has continuously been in the process of evolution. It is implemented depending on the requirements of situation. Many architectures or framework were proposed in order to support the development and to ease the implementation of context-aware systems. Special thrust has been put on characteristics related to the application domain and techniques used. Therefore, a survey of such architectures makes comparison between them. Their evaluation is strongly recommended. Earlier surveys are either restricted to a limited number of architectures or they do not offer a good comparison or their evaluation is not based on appropriate criteria which keep them as mere descriptions. The present survey/research is made with the aim finding out the relevant architectures which mark the evolution of context-aware systems based on criteria related to pervasive computing. The present study would serve as a guide to developers of context-aware systems and help them to make architectural choices.
