Service is the core concept of future Internet that named Internet of Services. This concept refers to software components as well as processing capacity and any other resources that can be offered through the Internet. There is a need for a third party that make registering and searching services easy and feasible. Web Service Technology (WST) is one of those current solutions to the Internet of services that has attracted much attention. Registering and searching of the services are feasible by use of Service Directory. The current structure of WST that is mainly based on UDDI suffers from some structural shortcomings. From a structural point of view, service directory is implemented as a centralized node that is a performance bottleneck and single point of failure.
