In our design, Web Servers are a cluster consisting of replicated Servers. Server predicates its load ,which is used to decide the cost to visit itself. Client makes the load balancing decision ,and caches the predicated load of Cluster. Based on price theory, Client chooses the server of the lowest cost to serve itself;at the same time,Server predicates the information updating speed of Cluster,and uses it to decide the updating speed of Cache. Finally ,the system topology is given and characters are analyzed.展开更多

The use of the reputation system is to address the free-rider problem. Database systems are used by directory agents to save information provided by load-server agents. Protocols are built for how a host finds available servers for load service or load transfer, especially when a host moves to a new region. Detailed procedures include how a directory agent builds its database, how a load-server agent provides services, and how a load-client agent receives its desired services. The system uses the fuzzy logic control method to transfer loads for load balancing, instead of the method of a fixed threshold level. For an ad-hoc (wireless) computer network framework, this new system structure is aimed to provide efficient ways for hosts to communicate with one another and to access resources in the system. This will also help the users of networks locate resources in a most effective and secure manner.展开更多
