Services delivered within a Grid environment are influenced by dynamic factors such as terminal capabilities, time of day and resource demand variation. There is thus a need for a dynamic negotiation protocol for the efficient support of heterogeneous services and pricing strategies that will exist in the Grid. We have proposed novel augmentations to existing service negotiation protocols in the areas of scalability, flexibility, support for distinct services and negotiation with several service providers simultaneously. The proposed autonomous negotiation protocol is based on a distributed multiagent framework creating an open market for Grid services. We have explained the consolidated protocol for Intra-domain and Inter-domain cases using specific scenarios that involve bi-lateral bargaining. Furthermore, the usefulness of our algorithm is exhibited by a categorical comparison made between the attributes of our protocol with the corresponding attributes of other key protocols in literature. In addition, our work is aligned with the FIPA and OGSA initiative.
