Originally viewed as a spinoff of MANETs [10], wireless sensor networks used a radically different line of attack that was
mostly platform- and application-driven [11]. Initially spearheaded by the smart dust vision [4,12] and fueled by a great deal
of military interest in the United States, the sensor network community went on to produce a decade’s worth of rich and
innovative research largely centered around the resource-constrained yet versatile Berkeley mote platform [13]. Although,
in principle, sensor networks are very close to the pervasive vision, their pervasiveness has always remained confined to
specific scenarios.
