CLEAR: An Efficient Context and Location-Based Dynamic Replication Scheme for Mobile-P2P Networks

We propose CLEAR (Context and Location-based Efficient Allocation of Replicas), a dynamic replica allocation scheme for improving data availability in mobile ad-hoc peer-to-peer (M-P2P) networks. CLEAR exploits user mobility patterns and deploys a super-peer architecture to manage replica allocation efficiently. CLEAR avoids broadcast storm during replica allocation and eliminates the need for broadcastbased querying. CLEAR considers different levels of replica consistency and load as replica allocation criteria. Our performance study indicates CLEAR's effectiveness in improving data availability in M-P2P networks.
