Multipoint conference systems in a ubiquitous environment

In a ubiquitous environment, people can communicate with others and have access to various computing services any time, any place. The multipoint conference systems in a ubiquitous environment are expected to be one of the leading applications to connect people. In this paper the various multipoint conference systems are compared for their efficiency in a ubiquitous environment and shows why the endpoint mixing conference scheme performs effectively in an ad hoc environment. However, the endpoint mixing conference scheme has its own drawbacks as well and we propose solutions for them.
