Message from the ACTICS 2011 International Workshop Organizers

The international workshop ACTICS 2011 is a forum for sharing ideas and research work in the emerging areas of advanced communication technologies and their applications to intelligent transportation systems, cognitive radio network and sensor networks. Due to the successful deployment of wireless cellular systems and wireless local area networks over the past decade, wired and wireless communication technologies and applications are dramatically increasing in different areas including vehicular communications to provide safety as well as comfort for passengers by providing timely information to drivers, cognitive radio systems for efficient spectrum utilization through opportunistic and dynamic spectrum access, and sensor networks for sensing and monitoring applications in different areas including homeland security, health, defense, energy, food safety, agriculture, environment, etc. The submitted papers went through a careful reviewing process and the workshop contains high quality research papers. We selected four papers for the presentation during the workshop and for the publications as proceedings. Selected papers are divided into two sessions for the presentation: Session 1 contains the papers related to cognitive radio systems, sensors and their applications, and Session 2 contains the papers related to protocols and algorithms for wireless sensor networks.
