Adaptive Safety Critical Middleware for Distributed and Embedded Safety Critical System

Distributed and embedded safety-critical systems (DESCS) are those systems whose failure could result in loss of life, significant property damage, or damage to the environment. Because of the nature of DESCS, designing the applications for DESCS is harder than those for distributed real-time embedded systems. In this paper, we describe a multilevel embedded safety-critical middleware called adaptive safety-critical middleware (ASCM) that provides related services for ease the development of embedded safety-critical applications. We also present multi-layer end-to-end adaptive Qos management technology to satisfy the dynamic and unpredictable mission requirements of DESCS.
