The mobile ad-hoc networks (MANETs) are decentralized network with resource constrained and mobile nodes. This characteristic of MANETS has a direct impact on the data availability. Replication has been used as one technique to improve the data availability both in MANETs and fixed networks. Data replication has an impact on the network resource utilization. In this paper, they propose a replica allocation scheme to reduce the communication cost while maintaining high consistent data availability. The proposed scheme builds group of 1-hop cluster of nodes in the network.
