Multi-threading processing of concurrent multiple continuous KNN queries based on cluster block
Hao Zhong-xiao · Journal of Qiqihar University · 2010
While search objects in a road network,we have research a continuous KNN neighbor search,but severs often receive a lot of query requests.For raise the efficiency of query and reduce the price of query.The clustering algorithm is proposed.Pipeline strategy and departed the continuous query processing into three simultaneous stages:query processing,query executing and query results dispatching.Experimental analysis proves the algorithm is better than others.
