摘要:

摘 要:引入转发证据的概念,设计了节点行为观测协议,提出一种基于信誉的双重Spray and Wait增强方案。通过对原始协议直接传输阶段的建模,使得信誉门限的确定建立在概率计算的基础上。仿真结果表明,在自私节点存在的环境中,与原始方案相比,增强方案能够减少自私行为对网络的危害,提高网络性能。

Abstract:

A concept of forwarding credential was introduced,and a detection protocol of behavior was designed.A novel scheme which enhanced the prevalent binary Spray and Wait routing scheme was integrated with reputation to resist the impairment of selfishness.According to the model of bundle transferring,the determination of reputation threshold was based on probability computation.The simulation results suggest that the enhanced scheme gain an advantage over original one under selfish misbehavior.

Key words: reputation, DTN, incentive schemes, routing
