A Survey on Cache Consistency Schemes Adopted in Manets


Mobile Ad hoc Network is a wireless communication network. It is a self configuring infrastructure less network of mobile devices. The mobile nodes in general access data from remote source from a wireless network. Hence any mobile nodes access latency is increased. To avoid this latency, mobile node cooperatively cache data in their local cache memory. Since Mobile Ad hoc Networks are dynamic in nature we must maintain consistency between the remote source and caching nodes. Some of the cache consistency schemes like pull based or client based and push based or server based are used to improve consistency of data. However, the main issue of concern is maintaining consistency such that the data at the server and the caching nodes are exact replicas at any point oftime.Hence,this survey describes various schemes used to improve consistency between the server and the caching nodes to reduce delays and network latencies. Moreover hybrid schemes that can make use ofthe advantages of both the push based and pull based schemes can be implemented for maintaining cache consistency.
