Robust K nearest neighbor query processing algorithm in wireless sensor networks

A robust K nearest neighbor query processing algorithm called ROC-KNN was proposed.It divides the query region into several sub-regions according the network topology.Each sub-region has a cluster node which collects the sensory data in it,sends it to the cluster node in the next sub-region until tr...
