Mobility & Cache Management Over Ensecure Routes In Adhoc Network

In this book, we have proposed a combined caching scheme to improve the communication performance of an MANET. A MANET is envisioned to provide access to information and services from anywhere anytime. The combined caching concept combines the local cache of each user (MC) in forming an unified cache that can alleviate the limited data accessibility and longer access latency problems. The caching scheme includes a broadcast-based search and a cache management technique. The proposed Broadcast Based search (BBS) algorithm ensures that a requested data is obtained from the nearest MC or AP. The combined cache management scheme has two parts: a cache admission control and a cache replacement policy. The admission control prevents high data replication by enforcing a minimum distance between the same data items, while the replacement policy helps in improving the cache hit ratio and accessibility. Three variations of the replacement policy are considered in this project by assigning different weights to the distance and time parameters of the SCR scheme.
