Abstract. The continued growth of both mobile appliances and wireless Internet technologies is bringing a new telecommunication revolution and has extended the demand of various services with mobile appliance. However, when working with wireless access devices, users have a limited amount of storage available to them due to their limited size and weight. In order to relieve this basic problem of storage capacity, we suggested iSCSI-based remote storage system for mobile appliance. However, iSCSI performance in the networks with high bit-error rates is degraded rapidly. Since iSCSI is designed to run on a TCP/IP network, it is influenced by an unnecessary reduction in link bandwidth utilization in the presence of high bit-error rates of wireless link. In this paper, we describe a new availability remote storage system for mobile appliance, called MiSC (as an abbreviation for multi-connectioned iSCSI), that avoids drastic reduction of transmission rate from TCP congestion control in wire...
