摘要:

为激励DTN自私节点在自身缓存有限时,有效地转发其他节点的消息,提出一种基于双向拍卖的拥塞感知激励策略。该策略中节点根据当前空闲缓存大小和消息接收速率确定自身拥塞程度,结合消息的传递概率和拥塞度并基于双向拍卖模型进行消息的买卖,从而实现节点间的合作。在真实数据集上进行仿真验证,结果表明由于进行了拥塞感知,该策略能够进一步激励自私节点进行合作转发,提高消息传递成功率,减小消息传递时延。

Abstract:

To stimulate the DTN selfish nodes to cooperatively forward messages when the buffer was limited, a congestion-aware incentive scheme based on double auction for DTN was proposed. In the scheme, nodes determined the self congestion degree according to the current free buffer and message receiving rate. Combining the message delivery probability and congestion degree, nodes traded the message based on double auction model, thereby achieved the cooperation between nodes. Extensive simulations were carried out on real-world traces to evaluate the proposed scheme. The experimental results show that, due to the congestion aware, the incentive scheme can further stimulate selfish nodes to cooperatively forward messages, improve the message delivery ratio and reduce the message delivery delay.

Key words: delay tolerant network, selfish, incentive, double auction, congestion
