MediaWiN 2009 is the fourth in a successful series of workshops which, since 2006,
has been organized in association with the IEEE Symposium on Computers and Communications (ISCC 2009). ISCC is an excellent forum for presenting ideas and results at the junction of communication and computation and provides the perfect framework for hosting the MediaWiN Workshop.
The Fourth Workshop on multiMedia Applications over Wireless Networks (MediaWiN) is an open forum, which aims at promoting interaction and discussion between the Workshop contributors. Starting with a rigorous review process in which each submitted paper will receive at least three independent peer reviews, including one from a TPC member, we expect the Workshop to provide relevant and knowledgeable feedback that will assist all authors to significantly enhance the quality of their work.
