In this paper, we introduce a peer-to-peer sensor network (P2PWSNDAS) architecture with pipelined time division scheduling for sensor data acquisition from an ad hoc wireless sensor network (WSN). P2PWSNDAS takes a service-oriented, data-centric view of the deployed WSN. The wireless sensors that constitute the WSN measure physical attributes of the(More)
Accurate localization in outdoor and indoor spaces is a challenging task. The widely used GPS is not designed for high accuracy applications and yields accuracy levels not sufficient for lane or spot level localization. In addition, errors from inertial sensors accumulate with time due to integration drift. We introduce a smartphone based, infrastructure(More)
