Resource Selection Strategies for a CNP-Based Resource Management Model

In this paper, we propose a resource management model that extends the contract net protocol by integrating the advantages of the matchmaking technique. Our model addresses the issues of matchmaker overload and the lack of up-to-date resource state information suffered by the original matchmaking model. It also enables resource requesters to obtain a list of qualified resources with which they can narrow down the selection of resources and reduce the number of ineffective communication messages. In addition, we present five strategies to facilitate resource selection on our model from the perspective of turnaround time and reporton experiments to evaluate their performance. The experiment results show that, in the presence of resource contention, the probabilistic strategies outperform random and the deterministic ones, and the performance of the presented strategies executed on our model is superior to their performance on the original matchmaking model.
