Abstract

Abstract

In order to alleviate the influence of network congestion in space delay/disruption tolerant networks, a QoS based congestion control algorithm is proposed in this paper. The algorithm consists of contact congestion forecasting scheme and QoS based data forwarding scheme. The contacts are divided into different congestion levels according to their residual available capacity and nodes storage resource. The congestion level of forwarding path calculated by routing is decided by the highest congestion level of contacts consisted in the path and different priority data will be forwarded according to the path congestion level. Experiment shows that QoS based algorithm could improve the transmission rate of data with lower priority and reduce the delivery delay of highest priority data when the node storage space is insufficient.
