Coverage and hole-detection in sensor networks via homology
We consider coverage problems in sensor networks of stationary nodes with minimal geometric data. In particular, there are no coordinates and no localization of nodes. We introduc...

KPT: a dynamic KNN query processing algorithm for location-aware sensor networks
An important type of spatial queries for sensor networks are K Nearest Neighbor (KNN) queries. Currently, research proposals for KNN query processing is based on index structures,...

Battery allocation for wireless sensor network lifetime maximization under cost constraints
Wireless sensor networks hold the potential to open new domains to distributed data acquisition. However, such networks are prone to premature failure because some nodes deplete t...
