FAST DATA COLLECTION IN TREE-BASED WIRELESS SENSOR NETWORKS

FAST DATA COLLECTION IN TREE-BASED WIRELESS SENSOR NETWORKS ABSTRACT: We investigate the following fundamental question – how fast can information be collected from a wireless sensor network organized as tree? To address this, we explore and evaluate a number of different techniques using realistic simulation models under the many-to-one communication paradigm known as converge cast. […]


ENHANCING PRIVACY AND ACCURACY IN PROBE VEHICLE-BASED TRAFFIC MONITORING VIA VIRTUAL TRIP LINES

ENHANCING PRIVACY AND ACCURACY IN PROBE VEHICLE-BASED TRAFFIC MONITORING VIA VIRTUAL TRIP LINES ABSTRACT : Traffic monitoring using probe vehicles with GPS receivers promises significant improvements in cost, coverage, and accuracy over dedicated infrastructure systems. Current approaches, however, raise privacy concerns because they require participants to reveal their positions to an external traffic monitoring server. […]
