The complex nature in the development of middleware for time-dependent system is challenging, since it facilitates more issues in proposing new models. In this paper, the need for developing context-aware middleware is investigated by considering time critical responses in real-time distributed applications. As a part of this, CoMiTe (context-aware middleware architecture) is proposed to support real-time distributed applications which employ time petri net based model to compute and communicate appropriate service. Based on InVANET Saravanan et al.(IEEE Explore 277–282, 2009), vehicle safety is considered as time critical service to evaluate the performance of the proposed middleware to assist drivers through context-aware safety measures.
