Abstract

Replication strategy is mostly useful for replicating the mobile user’s profile at selected locations where some callers have higher calling rate. It plays important role in personal communication services (PCS) in order to reduce call setup time and increase the QoS. We have proposed a novel and innovative replication tree which is based on the Huffman tree and there is interrelationship between the replicated sites based on their effective replication probability. In the proposed scheme, the total network traffic statistic data of a mobile user is considered to define effective replication probability.
