Agent-based Cloud computing generally includes a body of works involving the construction of agents for bolstering discovery, negotiation, composition, scheduling, workflow, and monitoring of Cloud resources.
Professor Benjamin Kwang Mong Sim is a pioneer and a leading researcher in Agent-based Cloud computing. Aside from being the first to coin the terms "agent-based Cloud computing", "Cloud intelligence", and "intelligent InterCloud" and providing the benchmark of cloud agents and the blueprint of an intelligent intercloud, he founded the world's first-ever Multiagent and Cloud Computing Systems Laboratory in 2008 and served as its Director. According to Google search, Professor Sim's paper entitled "agent-based Cloud commerce" published in 2009 is the earliest published paper documenting the idea of using intelligent agents for bolstering Cloud resource trading (discovery and negotiation) and his paper entitled "agent-based Cloud computing" is the most frequently cited paper on this topic. Professor Sim has contributed many award-winning innovations on agent-based Cloud computing, including foundational ideas, mathematical theory, models, protocols, testbeds, algorithms, and benchmark, as well as proof-of-concept software prototypes for supporting agent-based Cloud computing. He has also contributed two single-authored IEEE Transactions Survey-Tutorial papers on agent-based cloud computing, cloud intelligence, and intelligent intercloud and delivered several keynote lectures on agent-based cloud computing in IEEE-spored international conferences.

Technical Contributions
Foundational ideas: In 2009, Professor Sim introduced an agent-based paradigm for constructing tools and testbeds for Cloud commerce. His paper on agent-based Cloud commerce received an Outstanding Paper Nomination in an IEEE conference. Subsequently, his article on "Agent-based Cloud Computing" was selected as the Spotlight Paper of the October-December 2012 issue of the IEEE Transactions on Services Computing - one of the leading IEEE journals focusing on Cloud computing. In 2012, the IEEE Transactions on Services Computing was listed as one of the top IEEE Journals and ranked 5th out of 105 journals in computer science-software engineering. As of August 1, 2017, it has over 400 citations (according to Google scholar) and around 30,000 downloads in IEEE Xplore and it was the No. 5 Most Popular Article in IEEE Xplore in August 2014 among over 3.76 millions articles. In addition, Professor Sim's Spotlight Paper had been the No. 1 Most Popular Article in TSC for 33 consecutive months.
Vision: Professor Sim's vision of developing an intelligent InterCloud populated by a society of intelligent agents is summarized in his article entitleld "Cloud Intelligence: Agents within an InterCloud", published in the Awareness Magazine: The official magazine for Future and Emerging Technologies Proactive Initiative, funded by the European Commission under FP7.
Mathematical theory: Professor Sim's work on agent-based InterCloud game theory provides a mathematical theory for analyzing the interactions of stakeholders in an intelligent InterCloud. His paper entitled "Agent-based Interactions and Economic Encounters in an Intelligent InterCloud" was the No. 1 Most Popular Paper in IEEE Transactions on Cloud Computing in February 2017.
Models, protocols, testbeds, and algorithms: Professor Sim has contributed a large number of agent-based models, protocols, testbeds, and algorithms for bolstering the discovery, negotiation, composition, scheduling, workflow, and monitoring of Cloud resources.
Agent-based Cloud resource negotiation: Professor Sim is the first to introduce the idea of using bargaining as a new model for allowing dynamic pricing of Cloud resources and also the first to develop an agent-based testbed for Cloud service-level agreement (SLA) negotiation (published in 2009 and received an Outstanding Paper Nomination in the IEEE International Conference on Industrial Engineering and Engineering Management 2009). He also developed a concurrent negotiation model for simulating trading in a Cloud resource market. (which was first introduced in 2010). His concurrent Cloud negotiation model was published in the IEEE Transactions on Cybernetics (TCyb) and became the No. 1 Most Popular Paper in TCyb in December 2017. Furthermore, in 2013, his work on devising a unifying Cloud negotiation strategy received the Best Paper Award in the 2013 IAENG International Conference on Internet Computing and Web Services. Moreover, his laboratory has also devised an agent-based multi-issue Cloud negotiation mechanism that enables consumers and providers to reach service-level agreements on issues such as price, time slot, and quality of service.
Agent-based Cloud resource scheduling: Professor Sim is the first to introduce agent-based problem solving techniques for Cloud resource scheduling. His joint article with his ex-postdoctoral fellow on "A Family of Heuristics for Agent-based Elastic Cloud Bag-of-Tasks Concurrent Scheduling" ranked 19 among the top 25 hottest articles in the Future Generation Computer Systems Journal - one of the most popular forums in Cloud computing. Additionally, Professor Sim's laboratory devised 1) an algorithm for determining sets of Cloud resources that can be used to execute bag of tasks (BoT) applications constrained by both budgets and deadlines, and 2) an agent-based testbed that supports the dynamic Cloud resource allocation and distributed execution of BoT applications.
