Adaptive borrow-repay resource allocation on disruptive satellite communication with PEP

Adaptive borrow-repay resource allocation uses the positioning information when temporal communication disconnection is expected. It borrow the required bandwidth and repay later. Obstructions such as tunnels or buildings between satellite terminals and satellites may temporarily disconnect the satellite communication and result in the performance degradation of TCP. In this paper, we propose the novel adaptive borrow-repay resource allocation mechanism using cross-layer information exchange between an application layer and a link layer. The proposed allocation mechanism uses the positioning information of the satellite communication on the move (SOTM) node and the number of sessions. To evaluate the performance, we implemented a test-bed which includes the proposed mechanism. The experimental results show that the performance of the proposed mechanism can improves the TCP throughput and fairness for a temporarily disconnected satellite network user.
