  Abstract

In this paper, we propose VADAMA (Virtual Allocation Demand Assigned Multiple Access) which allocates virtually resources to all terminals in a satellite network and transmits the data. The DAMA (Demand Assigned Multiple Access), which is the resource allocation technique of the existing satellite network standard, causes a delay time of about 500 msec since it transmits a control message to the NCC (Network Control Center) before data is transmitted. Therefore, if it is applied to the burst traffic environment, the control message is transmitted in units of bursts, which degrades network performance. In order to solve this problem, CFDAMA (Combined Free Demand Assigned Multiple Access) has been suggested, but only be effective in low traffic load. In this paper, the delay time is reduced by virtually allocating the satellite resources to the terminals so that the transmitting terminal and the receiving terminal can determine the data transmission channel without controlling the NCC. Futhermore, we have confirmed through simulations that the performance of the proposed sheme is improved compared to the existing scheme.
