Robust performance of Cooperative Cache wireless P2P Networks Architecture and Algorithm

Abstract:Mobile ad hoc networks have potentialapplications in civilian and militaryenvironments such as disaster recoveryefforts, group conferences, wirelessoffices, mobile info-stations (intourist centers, restaurants, and so on), and battlefieldmaneuvers, making them a focus of currentresearch.Cooperative caching, which allows the sharing and coordination of cached data among multiple nodes and in this paper we are discussing about the data pipelines, by using these to reduce the end-to-end delay. To increase data accessibility, mobile nodes shouldcache different data items than their neighbors.Although this increases data accessibility, it also canincrease query delays because the nodes might haveto access some data from their neighbors instead ofaccessing it locally. In addition, replicating data fromthe server could create security problems.We propose a asymmetric cooperative cache approach, where the data requests are transmitted to the cache layer on every node, but the data replies are only transmitted to the cache layer at the intermediate nodes that need to cache the data. So our results show that the asymmetric Cooperative cache schema provides the data with less amount of delay time.
