Distributed Cache Model with Stability and Storage Management for MANET
Pervasive Internet Access is supported under the Wireless ad hoc network. There is no support of any fixed infrastructure in a wireless ad hoc network environment. Wireless adhoc networks are constructed using smartphone, laptop, PALM-top, and sensor devices. Wireless ad hoc networks are resource constrained in terms of bandwidth and power. The network nodes are communicates with the multihop paths. A packet can be overheard by a wireless node due to the broadcast nature of wireless communication. Data caching is widely used to efficiently reduce data access cost. Overheard data values can be maintained in data caches for fast data delivery. Data overhearing techniques are used to provide the cooperative cache facility. Data request and data reply are overheard to optimize cache placement and cache discovery. Cache placement mechanism is used to assign data under cache nodes. Cache storages are provided in the overheard nodes. Cache discovery process is used to identify a requested data from the cached data collection. The overhearing aided cache management mechanism is designed to manage cache placement and cache discovery process. Cache placement algorithm is used to assign cache data values. Data access cost and transmission cost factors are used in the data request process. Data consistency feature is adapted in the overhearing aided cache management mechanism. Cache management mechanism is used to maintain the cache storage levels. Cache storages are maintained with node movement factors. Multiple cache copies are maintained with primary and secondary cache models.
