Double-ruling-based location-free data replication and retrieval scheme in mobile ad hoc networks

Using the double-ruling technique, many data replication and retrieval schemes achieve low data retrieval latency. However, none of these schemes are location-free schemes in mobile ad hoc networks (MANETs). In this paper, we propose a zero-knowledge double-ruling-based location-free data replication and retrieval scheme (MobiMark) in MANETs. Our primary idea is to label the grid-like structured landmarks in the network using the landmark-labeling, dynamically designate the node that is nearest to a landmark as the landmark broker, and transmit the consumers' interests (or producers' data) to all horizontal (or vertical) landmark brokers using the double-ruling technique. Simulations show that MobiMark achieves good performance in terms of data retrieval rate and data retrieval latency.
