Abstract: Using a single cloud datacenter in Cloud network can
have several disadvantages for users, from excess energy consumption to increase
dissatisfaction of users of service and price of provided services. The Cloud
broker as an intermediary between users and datacenters can play a key role to
enhance users' satisfaction and reducing energy consumption of datacenters that
are located geographically in different areas. In this paper, we have attempted
to provide an algorithm that assigns datacenter to users through rating various
datacenters. This algorithm has been simulated by Cloudsim and will result in
high levels of user satisfaction, cost-effectiveness and improving energy
consumption. In this paper, we show that this algorithm can save 44% of energy
consumption and 7% of cost saving to users are in sample simulation space.
Keywords: Cloud network, cloud broker, energy optimizing,
