چکیده مقاله
Multicast data replication provides a possible solution for improving data accessibility in highly dynamic and fault prone mobile ad hoc environments Our novel multicast data replication approach operates in a self organizing manner where the network nodes that has unit host detector construct a connected dominating set CDS based on the topology graph by collecting information from neighboring nodes using multicast if gathered data from neighbors have two non adjacent neighbors then use that virtual backbone for efficient data replication, data search and routing In this study, we compare our proposed approach with SCALAR and evaluate it in average hop counts and successful delivery ratio with different node numbers and speeds It is shown that the average hop counts increased but with falling rate and 20 percent successful delivery ratio is achieved, so it is demonstrated that PM act with respect to fault tolerance improvement, power consumption and load balancing is occurred
