Efficient Data Accessibility using TTL Based Caching Strategy in Manet
MANETs or Infrastructure less networks are collection of mobile nodes which forms a temporary network without the aid of centralized administration or standard support devices regularly available in conventional networks. One of the effective techniques to avoid the stale data is cache invalidation, which maintains data consistency between the client cache and the server. If data caching is not implemented, the request for the same data item has to be sent to the source node each and every time. This will cost more time delay, bandwidth, power consumption, etc. Cache refresh and TTL reset of Adaptive TTL scheme produce some process overhead to the cache node.
