| 摘 要： | 针对机会网络简单"物-物交换"(SBT)激励机制降低网络性能的问题,设计了一种基于债务的"物-物交换"(DBT)激励机制.DBT通过引入债务关系改变了SBT中严格的等价交换原则,增加了单次交易的转发数据量,从而提高了网络性能.为使债务关系可靠运行,设计了基于信任的惩罚机制和基于债务的缓存策略.仿真实验证明,和SBT相比,DBT在有效激励节点协作的同时提高了网络性能.

| Abstract: | In order to solve the problem that existing simple barter trade ( SBT) incentive mechanisms in opportunistic networks degrade the network performance, a debt-based barter trade ( DBT ) incentive mechanism was proposed. The DBT changes the rigid equivalent barter trade principal in SBT by introdu-cing debt relationship, which increases the number of forwarding data in a single trade and then improves the network performance. A trust-based punishment scheme and a debt-based caching strategy was de-signed to guarantee that debt relationship credibly run. Simulations show that DBT can obtain better net-work performance than SBT and effectively motivate nodes' cooperations. |
