Since the ?rst event in 2002, WWIC has been established as a highly selectiveconferencefocussingonthe rapidlydeveloping?eldof wirelessnetwo- ing, and providing an international forum for the presentation and discussion of cutting-edge research in the ?eld. The WWIC 2009 call for papers attracted 39 submissions from 20 countries, which were subject to thorough review by the Technical Program Committee members and additional experts. The selection process resulted in the acc- tance of 13 papers, organized into 4 technical sessions. The major themes of WWIC this year were energy e?ciency, security, reliability, and routing p- tocols in wireless sensor and ad hoc networks as well as handover and mobility managementin heterogeneousenvironments.
