Heuristic algorithms for effective broker deployment

摘要: In the pervasive e-business applications cov- ering large geographical areas and involving many RFID readers or sensors, broker deployment strategies have a direct effect on cost collaboration efficiency. By analyzing collab- oration basis, this paper proposes model for problem, presents two heuristic algorithms multi-object optimization of deployment, where one is area which contains zones forbidden to place brokers in, other without any zone. Experiments are conducted demonstrate effectiveness proposed algorithms. The experimental results also show advantage being low deployment. Moreover, deployed carry relatively balanced loads messages forwarded from an event source over small number hops.
