Client Based Cache Consistency Scheme in Wireless Mobile Networks
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 3
Abstract
Abstract: This paper proposes a client based cache consistency scheme for maintaining cache consistency in wireless mobile networks using a distributed cache invalidation method. This is implemented on top of a previously proposed architecture for caching data items in mobile ad hoc networks (MANETs), namely COCAS. We have also previously proposed a client and server based consistency scheme, named SSUM and DCIM. Client based cache consistency scheme is a pull-based algorithm that implements adaptive time to live (TTL), piggybacking, and prefetching, and provides strong consistency capabilities. We assign an adaptive TTL value to the cached data items in the data source depending on their update rates, where items with expired TTL values are grouped in validation requests to the data source to refresh them. But the unexpired ones with high request rates are prefetched from the server.
