A message from the General Chair

Ad hoc networks have attracted the attention of the research community in the last several years.

Med-Hoc-Net 2009 is an annual international workshop aiming to serve as a forum where researchers from academia, research labs and the industry from all over the world, meet to share ideas, views, results, and experiences in the field of ad hoc networking.
