摘要 Cache invalidation is an effective approach to maintaining data consistency between the server and mobile clients in a mobile environment. This paper presents two new cache invalidation schemes which are designed according to the real situations and are therefore able to comply with the more practical needs in a mobile environment. The ABI+HCQU divides data into different groups based on their utilization rates (hot/cold/query/update) and adapts their broadcasting intervals (ABI) accordingly to suit the actual needs. The SWRCC + MUVI (sleep/wakeup/recovery/check/confirm+modified/uncertain/ valid/ invalid) aims to solve the validity problem of cached data after a client is disconnected from the server. The new cache invalidation schemes are shown through experimental evaluation to outperform most existing schemes in terms of data access time, cache miss rates and bandwidth consumption.
