Traditional techniques for processing continuous queries on moving objects reduce query re-computing through single-threaded and shared execution between multiple queries, and don’t make use of the parallel computing capabilities of the ubiquitous multi-core CPUs. Thus, to explore this kind of parallelism, a
ueries (MFCQ) is proposed which adopts a strategy of re-computing all of the queries periodically. The framework divides the query process into three phases:the updating, optimization and execution stages; multi-threading based methods are used in each phase. Moreover, the framework is deemed to be general, because it is compatible with various index techniques and query algorithms. By using the framework, a query index based KNN algorithm and an object index based KNN algorithm are proposed respectively. Experimental results show that the multi-threading framework executed on the multi-core platform outperforms the traditional YPK-CNN algorithm.
