The focus of situation-aware ubiquitous computing has increased lately. An example of situation-aware applications is a multimedia education system. Since ubiquitous applications need situation-aware middleware services and computing environment keeps changing as the applications change, it is challenging to detect errors and recover them in order to provide seamless ser- vices and avoid a single point of failure. This paper proposes an Adaptive Fault Tolerance Agent (AFTA) in situation-aware middleware framework and pre- sents its simulation model of AFT-based agents. The strong point of this system is to detect and recover error automatically in case that the session's process comes to an end through a software error.
