Abstract

As mobile devices prevail, requests for various services using mobile devices have increased. Requests for application services that require large data space such as multimedia, game and database[1] specifically have greatly increased. However, mobile appliances have difficulty in applying various services like a wire environment, because the storage capacity of one is not enough. Therefore, research [5] which provides remote storage sercives for mobile appliances using iSCSI is being conducted to overcome storage space limitations in mobile appliances. But, when iSCSI is applied to mobile appliances, iSCSI I/O performance drops rapidly if a iSCSI client moves from the server to a far away position. In the case of write operation, 28% reduction of I/O performance occurred when the latency of network is 64ms. This is because the iSCSI has a structural quality that is very sensitive to delay time. In this paper, we will introduce an intermediate target server and localize iSCSI targer to improve the shortcomings of iSCSI performance dropping sharply as latency increases when moblie appliances recede from a storage server.
