An Adaptive Reliable QoS for Resource Errors Running on Ubiquitous Computing Environments

The ARQ_RE model is proposed for supporting QoS resource errors detection-recovery in the situation-aware middleware. An example of situation-aware applications is a multimedia education system. QoS guarantees must be met in the application, system and network to get the acceptance of the users of multimedia communication system. There are several constraints which must be satisfied to provide guarantees during multimedia transmission. They are time, space, device, frequency, and reliability constraints. We propose a method for increasing reliability through an Adaptive Reliable QoS for Resource Errors (ARQ_RE) model for ubiquitous computing environments. The model aims at guaranteeing it through application QoS.
