Distributed faulty node detection and isolation in metropolitan-area delay-tolerant vehicular sensor networks are investigated in this paper. For the intermittently connected large-scale dynamic networks, we design a practical faulty node detection algorithm that vehicles can perform on board to detect faulty sensors by utilizing the local data's spatial correlation. Based on the distributed detection...
We are interested in event collection in a 2D region where sensors are deployed to detect and collect interested events. Using traditional multi-hop routing in wireless sensor networks to report events to a sink node or base station, will result in severe imbalanced energy consumption of static sensors. In addition, full connectivity among all the static sensors may not be possible in some cases since...
