Efficient cache invalidation in mobile environment
Narottam Chand, R. C. Joshi, Manoj Kumar Misra · 2005
Caching at mobile client can reduce number of uplink requests, lighten server load, shorten query latency and increase data availability. A cache invalidation strategy ensures that cached data by a mobile client has same value as on the origin server. This paper presents a synchronous stateful caching technique with the objectives to reduce the query latency, minimize the overheads due to client disconnection, reduce the use of wireless channel and conserve the client energy. Simulation results show that our strategy performs better than IR and UIR schemes.
