Abstract

A situation-aware middleware provides standardized communication protocols to interoperate an application with others under dynamically changing situations. Since the application needs of middleware services and computing environment (resources) keep changing as the application change, it is difficult to analyze: 1) whether it is possible that all Quality of Service (QoS) requirements are met, 2) and what QoS requirements have tradeoff relationships. In this paper, we propose a QoS resource conflict identification model called "QoS-Mission-Action-Resource (Q-MAR)" for situation-aware middleware. The Video On Demand (VOD) system is used as an illustrative example of the Q-MAR model and its resource conflict identification.
