【 摘 要 】

Advanced reservation has been used in grid environments to provide quality of service (QoS) and to guarantee resources available at the execution time. However, in grid subtypes, such as opportunistic grid computing, it is a challenge provides QoS and guarantee of availability resources. In this article, we propose a new advanced reservation approach which offers to a user the possibility to select resources in advance for a future utilization. Therefore, the main goal of this proposal is to offer a best effort feature to a user from an opportunistic configuration. In these types of environments, it is not possible to provide QoS, because, usually, there are no guarantees of resources availability and, consequently, the execution of users applications. In addition, this research work provides a way to organize executions, what it can improve the scheduling and system operations. Experimental results, carried out through a case study, shown the efficiency and relevance of our proposal.
