An intelligent error detection-recovery system for multimedia CSCW based on situation-awareness: AEDRS

This paper presents the design of the AEDRS(An Adaptive Error Detection-Recovery System), which is running on situation-aware middleware. Situation-aware middleware provides standardized communication protocols to interoperate an application with others under dynamically changing situations. The focus of situation-aware ubiquitous computing has increased lately. An example of situation-aware applications is a multimedia education system. The development of multimedia computers and communication techniques has made it possible for a mind to be transmitted from a teacher to a student in distance environment. This paper proposes an Adaptive Fault Tolerance (AEDRS) algorithm in situation-aware nliddleware framework and presents its simulation model of AEDRS-based agents. EDRA provide several functions and features capable of developing multimedia distant education system among students and teachers during lecture. AEDRS is a system that is suitable for detecting and recovering software error based on distributed multimedia education environment as EDRA by using software techniques.
