There is an increase in the process of caching valid regions of location based queries (spatial queries) at mobile clients. It is effective in reducing when the number of queries is posted by mobile clients and the sending queries are loaded on the server. Due to this mobile clients are suffered. That is, mobile clients are waiting for a long time for the server to answer for the posted queries. The proxy-based approach to continuous Nearest-Neighbor (NN) and window queries was proposed.
