摘要：In this paper, proposed a solution for replica placement onto mobile hosts which are continuously moving and disconnections occur by unstable radio links, which are likely to be disconnected after a short time. Consider an Ad Hoc network in which mobile hosts are entered and communicate with other mobile hosts in the network and get replicas from the neighbors, while accessing the data items disconnections may occur due to unstable radio links. In this way accessing the data items is difficult. In this paper, develop a mechanism to access the data items from the mobile hosts after disconnection occur for short time. The proposed mechanism works efficiently in mosaic networks also. The technique incorporates the access frequency from mobile hosts to each data object, the status of the network connectivity by exhibit an adjacent matrix, and communication costs, which are very low by accessing data items from nearest neighbors. The derived mechanism is general, flexible and adaptable to cater for various applications in ad hoc networks. This approach is efficient in both execution time and solution quality.
