“…These speeds are determined by the random walk model [14] and the communication range is set to 70 m. We will be using (13,13,4,4,1) BIBD design network partitioning where we divide 65 nodes in to 5 partitions. The size of each data item is 1 [MB].…”

“…Other than (7, 7, 3, 3, 1)-configuration, some other examples of balanced incomplete block design are (12,9,4,3,1), (13,13,4,4,1), (21,21,5,5,1), (26,13,6,3,1), (35,15,9,3,1) and etc. If the number of data items in the data blocks in a node is 3, the network organization would be simple and this design can be exploited by clustering and other partitioning schemes.…”

“…These can cause multiple disjoint partitions. Recent studies [1], [2], [25] show the serious consequences of data loss and lack of data availability due to the lose of communication links in MANETs. Since MANETs are used for communication among soldiers in the battle fields, search and rescue missions, law enforcement activities and information sharing, data loss and lack of data availability are significant threats for these vital operations.…”

Data replication increases data availability in Mobile Ad Hoc Networks (MANETs). Preventing data loss and increasing data availability in MANETs is a nontrivial problem due to their low-cost hardware, harsh working environments, node mobility, failure of mobile devices from battery exhaustion and node compromise attacks. In addition, different routing algorithms and larger size of the network can cause communication links to fail creating several disjoint partitions which causes data loss. The typical fault-tolerant systems would fail in these conditions. Existing approaches fail due to the limitations caused by their dependence on lower node mobility or constrained by node distribution, unpredictable partitions and routing mechanisms. In this paper, we propose Combinatorial Replication and Partition (CORP) of data which is a combinatorial arrangement with pairwise balanced design property to prevent data loss and increase data availability. Our scheme provides low access latency and reduces communication overhead. By partitioning and replicating data in such a combinatorial arrangement, our scheme directly supports objectoriented constructs in distributed fault-tolerant networks.

“…The placement of mobile hosts in logical groups is helpful in capitalizing REALM on this common MANET application semantic. The mobile hosts are included in each logical group to access equal data items Vallur et al (2008). The selected group-based mechanisms and their anatomy are described in Section 2.…”

“…A data replication technique has been proposed by Vallur et al (2008) for A Logical group-based MANET real-time databases (REALM). The proposed technique is able to take advantage of the needs of the clients in the network at the replication time by considering groups of mobile hosts which access the equal set of data items.…”

Purpose A mobile ad hoc network (MANET) enables providers and customers to communicate without a fixed infrastructure. Databases are extended on MANETs to have easy data access and update. As the energy and mobility limitations of both servers and clients affect the availability of data in MANETs, these data are replicated. The purpose of this paper is to provide a literature review of data replication issues and classify the available strategies based on the issues they addressed. Design/methodology/approach The selected articles are reviewed based on the defined criteria. Also, the differences, the advantages and disadvantages of these techniques are described. The methods in the literature can be categorized into three groups, including cluster-based, location-based and group-based mechanisms. Findings High flexibility and data consistency are the features of cluster-based mechanisms. The location-based mechanisms are also appropriate for replica allocation, and they mostly have low network traffic and delay. Also, the group-based mechanism has high data accessibility compared to other mechanisms. Data accessibility and time have got more attention to data replication techniques. Scalability as an important parameter must be considered more in the future. The reduction of storage cost in MANETs is the main goal of data replication. Researchers have to consider the cost parameter when another parameter will be influenced. Research limitations/implications Data replication in MANETs has been covered in different available sources such as Web pages, technical reports, academic publications and editorial notes. The articles published in national journals and conferences are ignored in this study. This study includes articles from academic main international journals to get the best capability. Originality/value The paper reviews the past and the state-of-the-art mechanisms in data replication in MANET. Exclusively, data replication’s main goal, existing challenges, research terminologies and mechanisms in MANET are summarized using the answers to the research questions. This method will help researchers in the future to develop more effective data replication method in MANET.
