摘要: 為了解決現(xiàn)有中繼激勵機(jī)制中長期回報存在不確定性，以及即時回報導(dǎo)致資源利用效率降低的問題，該文針對協(xié)作下行通信系統(tǒng)提出一種復(fù)合中繼激勵機(jī)制(CCRI)。首先利用鏈路不平衡產(chǎn)生的瓶頸，將第1跳鏈路超過第2跳的數(shù)據(jù)速率部分作為即時回報，用于中繼節(jié)點(diǎn)自身數(shù)據(jù)的傳輸；同時針對即時回報量不足，過量或瓶頸存在于第1跳導(dǎo)致即時回報失效的情況，采用基于比例公平的長期回報作為補(bǔ)充，進(jìn)一步調(diào)整中繼節(jié)點(diǎn)的調(diào)度權(quán)重。仿真結(jié)果表明，所提機(jī)制能夠給予中繼節(jié)點(diǎn)合理的回報，并實(shí)現(xiàn)系統(tǒng)頻譜效率和生存時間，以及中繼能量效率的改善。

Abstract: In order to overcome the uncertainty of the reward with long-term relay incentive strategy and the degradation of resource utilization efficiency incurred by the short-term incentive scheme, a Cooperative Compound Relay Incentive (CCRI) mechanism is proposed for cooperative downlink communication system. By exploiting the bottleneck resulted from the imbalance of links capability, the rate difference that the first hop exceeds the second is provided as an instant reward for the relay nodes own data transmission. In addition, by taking into account the situations where the short-term reward is insufficient, excessive or the bottleneck exists in the first hop in such a case that the short-term incentive scheme becomes unavailable, a proportional fair based long-term incentive is employed as supplementary, with which the relay nodes scheduling weight is further adjusted. Simulation results show that the proposed scheme can provide rational reward to the relay and achieve improvements of systems spectral efficiency and lifetime, as well as relays energy efficiency.-
