Distributed Cache Invalidation Method using Extended Adaptive Time to Live Mechanism for Cache Consistency in Wireless Mobile Network

Sonali S. Shukla, Yashwant Ingle

Abstract: DCIM is a Distributed Cache Invalidation Method is used for maintaining cache consistency in wireless mobile network. DCIM is analysed for assessing delay time and bandwidth gain and compared for polling time. DCIM is a client based cache consistency schemes for caching data in wireless mobile network. DCIM is also used as a pull based algorithm for implementing Time to live, piggybacking and prefetching. An adaptive time to live (ATTL) For cache maintenance an adaptive TTL mechanism is used in DCIM that has update rates of data sources to update cache, where expired TTL values is grouped in validation requests rates are prefetched from the server. Existing system has used an adaptive TTL mechanism which contains some limitations like maximum request time, degraded system performance due to which the speed of communication reduces and data received is not reliable. Here the cache maintenance will be doing using EX-ATTL mechanism which will provide hash table for cache invalidation between each 1-hop distance node to data cache node. In this paper all this mechanism will reduce the overhead of the cache node to increase the speed of communication. This proposed mechanism will also reduce the request data delay time due to which the system performance get improved and will provide a reliable data.
