Decentralized services orchestration using intelligent mobile agents with deadline restrictions

Abstract

The necessity for better performance drives service orchestration towards decentralization. There is a recent approach where the integrator - that traditionally centralizes all corporative services and business logics - remains as a repository of interface services, but now lacks to know all business logics and business workflows. There are several techniques using this recent approach, including hybrid solutions, peer-to-peer solutions and trigger-based mechanisms. A more flexible approach regarding environment configuration and not fully explored in services orchestration technology is the use of intelligent mobile agents to execute it. In this paper, we present new adaptive heuristics for mobile agents to execute the decentralization of orchestration through missions (services) that correspond to the stages of business flow, with the ability to trade-off the quality of the result with the deadline of the mission. Some test case scenarios are presented and collected data are analyzed pointing the advantages and disadvantages of each heuristic. © 2010 IFIP.
