Mobile Learning [Guest editor´s introduction]

Wireless sensor networks (WSNs) have attracted significant interest from both computer science academia and industry in recent years. My colleagues and I introduced a postgraduate WSN course to the University of Melbourne´s Master of Engineering in distributed computing program (www.eng.unimelb.edu.au/courses/pgrad/courses/grad_medc.html). I first taught sensor networks and applications (CSSE 433-654) in 2006 and will teach it again this year, having learned from the unexpected challenges that arose in the first round.
