A Model of Service Scheduling Based on Market Mechanism and Semantic

摘要

We should do service scheduling in pervasive environments. By comparing some present resource scheduling methods and discussing the importance of combining the market mechanism with semantic, we propose a model of service scheduling based on market mechanism and semantic (Market-Semantic). It includes the similarity measure between ontologies, the ascertaining of utility functions and resource price. By designing a new method to measure the similarity between ontology, and by looking on the ratio of capability and cost as the utility functions, we explore a method of service scheduling by which users not only can get the service satisfied, but also the resource can be allocated efficiently, Finally, the experiment proves that our method is better than the methods of Max-Semantic and Semantic-Cost-Max-Min.
