Utility-based barter trade incentive scheme in opportunistic network
摘要
Abstract
In opportunistic networks, existing simple barter trade (SBT) incentive scheme degraded the network per-formance due to the blindly caching strategy. So a utility-based barter trade (UBT) incentive mechanism was proposed. In the UBT scheme, nodes cache messages by predicting their future encounters and the probability that the encounters for-ward these messages to their destinations, which improved the caching efficiency and the network performance. Simu-lated results show that, compared with SBT, UBT can obtain higher delivery ratio and lower delay by less network cost and effectively motivate nodes’ cooperation as well.关键词
