AHP Based Cooperative Cache Path Support in Mobile Ad hoc Network

All wireless networks possess self-organizing architecture with an infrastructure-less feature to combine and form an Ad Hoc network called MANET (Mobile Ad Hoc network). All mobile nodes working under this network are routers and they are connected through wireless links in those networks. Mobile routers in the wireless network have the freedom to move and they have ability to organize themselves arbitrarily. This feature makes wireless topology to change very often and the data predictability in such a dynamic environment becomes complex. This makes the data access in such environment weak and data loss may occur due to intermittent network connections. Therefore, the restricted power supplies make way for data loss. Therefore, enhanced method with Cooperative cache path is proposed in this paper. This method deals with time and energy efficient technique for local communication with an efficient caching algorithm using Analytic Hierarchy Process. Data Sharing and mobile node coordination of cached data among multiple mobile nodes enable better cache performance to have quick data access with proper latency and enhances data availability in a frequently changing dynamic mobile environment. Proper selection of wireless path with optimal solution gives significant improvement in performance of the network. This paper targets and concentrates on selecting the effective routing cache paths to transfer data in those paths by considering multiple criteria using AHP method.
