Abstract:
By increasing the use of Internet and sharing information in this platform, servers are equipped with more robust hardware and a wider bandwidth network. But the growth of data and services is such that a server, no matter how powerful, does not have the ability to respond all users! Several servers are used to solve this problem. Data centers, content delivery networks, and so on are emerged depending on types of service. One of the important issues in these systems is how to distribute loads between servers in a proportional manner. In this thesis, we first examine the relationship between cost and response time on user requests. Cost can be considered as a communication cost or financial cost. Then, we provide a heuristic algorithm using honeybee scheme to control the cost of load balancing, in addition to reducing the response time. Finally,by developing a simulator, the proposed algorithm will be tested and compared in other ways
