A Data Replication Scheme based on Primary Copy for Ensuring Data Consistency in Mobile Ad hoc Networks

Abstract - A mobile ad hoc network (MANET) is a multihop wireless network capable of autonomous operations. Since MANET causes frequent network partitions, a data replication is considered as a way to increase the data accessibility and the availability of transaction processing. If the database is replicated among mobile hosts, additional energy is required to keep data consistency. We propose a data replication scheme for MANET, which provides data consistency and increased number of successful committed transactions reducing energy consumption. The proposed scheme updates the data in the primary copy, which guarantees the latest value of the data item. If an application wants the latest version of data, it should refer to the primary copy; otherwise it accesses the local copy of the data. When the application does not require the latest version, our scheme approves the access of the data item to the local copy. It can improve the energy efficiency by reducing the additional number o...
