A context-aware cache structure for mobile computing environments

摘要: This paper proposes a cache management method that maintains mobile terminal's content by prefetching data items with maximum benefit and evicting entries minimum benefit. The item is evaluated based on the user's query context which defined as set of constraints (predicates) define both movement pattern information requested user. A context-aware formed maintained using neighboring locations (called prime list) are restricted validity fetched from server. Simulation results show proposed strategy, different levels granularity, can greatly improve system performance in terms hit ratio.
