Frequency Hopping Packing Algorithm for MF-TDMA with Various Types of Satellite Terminals

In this paper, we propose an anti-jamming resource allocation scheme based on reserve channel with priority (RCP) fit algorithm for multi-frequency, time division multiple access (MF-TDMA) technology in satellite networks. The RCP fit allocates the traffic of the same terminal on the same frequency channel. In the RCP fit, partial bandwidth noise jamming (PBNJ) can corrupt the traffic of the specific terminals in jamming channels, and results in a fairness problem. Therefore, we extend the RCP fit to frequency hopping RCP (FH-RCP) fit, which prevents PBNJ using two steps. The first step is control channel frequency hopping to prevent continued jamming of the control channel, which forces the terminals to log out. The second step is data traffic frequency hopping, which enables various kinds of traffic to hop frequencies. FH-RCP fit thus applies the FH technique in a media access control layer, especially in MF-TDMA. Simulation results show that the proposed scheme improves anti-jamming capability and increases fairness compared to the RCP fit under PBNJ.
