Objective of the present work is to improve range query performance using Hybrid Spatial Air Index (HSAI). HSAI has been designed with combination of both cache management and network coding for processing range queries in road networks. HSAI has been utilized the advantage of both cache management and network coding and reduce client search space. The experiments have been conducted for evaluating performance, the experimental results show that HSAI outperform.
Spatial Air Index (SAI) has been proposed for improving query performance of k-nearest neighbour queries in road networks. SAI has been effectively utilized the usage of Adaptive Cooperative Caching (ACC) and reduced search space. Experiments have been conducted for evaluated query result, the experimental result show that SAI outperform compared to state-of-the-art Network Partition Index (NPI).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
