The requested geospatial data have the characteristics of spatial and temporal locality. This paper proposed an expression for the replacement fea- ture by balancing spatial and temporal locality as well as long-term and short-term popularity in tile access to ensure that the replacement process can not only optimize global access but also adapt to the access pattern changes. Then, using the Hash function and linear linked chains to provide cooperative cache management in a heterogeneous cluster-based cach- ing system speeds up the query and replacement process of tiles and improves the performance of the cluster-based cache service. Experimental results revealed that the proposed method obtained a higher cache hit rate and a good average re- sponse performance for a heterogeneous distributed cluster-based cache system, providing TI - Replacement Method based on Access Spatiotemporal Locality in a Heterogeneous Distributed Cluster-based Caching System for WebGIS JO - The Open Cybernetics & Systemics Journal DO - 10.2174/1874110x01509010663 DA - 2015-06-26 UR - https://www.deepdyve.com/lp/unpaywall/replacement-method-based-on-access-spatiotemporal-locality-in-a-jAkkyMritB DP - DeepDyve ER -
