【摘要】：內(nèi)容由于移動(dòng)對(duì)等網(wǎng)絡(luò)的自組織、開(kāi)放性以及節(jié)點(diǎn)資源受限等特點(diǎn),一些節(jié)點(diǎn)表現(xiàn)出其自私性或惡意性。針對(duì)該問(wèn)題,給出了一種基于討價(jià)還價(jià)動(dòng)態(tài)博弈的節(jié)點(diǎn)激勵(lì)策略DGBIS(incentive strategy based on dynamic game of bargaining in mobile P2P network)。該激勵(lì)策略采用虛擬貨幣的支付方式,節(jié)點(diǎn)先根據(jù)其擁有的虛擬貨幣量、自身資源狀態(tài)和消息屬性對(duì)每次消息轉(zhuǎn)發(fā)進(jìn)行估價(jià),然后交易雙方基于估價(jià)通過(guò)三次討價(jià)還價(jià)動(dòng)態(tài)博弈以合理的報(bào)價(jià)進(jìn)行交易。通過(guò)博弈分析給出了DGBIS策略的納什均衡解,使理性的自私節(jié)點(diǎn)為最大化其自身利益而積極參與消息轉(zhuǎn)發(fā)合作,同時(shí)能抑制惡意節(jié)點(diǎn)的虛假報(bào)價(jià)。分析與實(shí)驗(yàn)結(jié)果表明,該激勵(lì)策略能提高整個(gè)系統(tǒng)的消息轉(zhuǎn)發(fā)成功率,降低系統(tǒng)的能量消耗,達(dá)到了預(yù)期的設(shè)計(jì)目標(biāo)。
[Abstract]:Some nodes show selfishness or malice due to the characteristics of self-organization, openness and resource limitation of mobile peer-to-peer networks. In order to solve this problem, a node incentive strategy based on bargaining dynamic game (DGBISincentive strategy based on dynamic game of bargaining in mobile P2P network) is presented. The incentive strategy adopts the payment method of virtual currency. The node evaluates each message forwarding according to the amount of virtual currency, the status of its own resources and message attributes. Then the two parties trade on the basis of valuation through three bargaining dynamic games. The Nash equilibrium solution of the DGBIS strategy is given by game analysis, which makes the rational selfish node participate in the message forwarding cooperation in order to maximize its own interests, and at the same time it can restrain the false quotation of the malicious node. The analysis and experimental results show that the strategy can improve the success rate of message forwarding, reduce the energy consumption of the system and achieve the desired design goal.
