【摘要】 为了解决无线自组织网络中转发节点因自身能量与存储空间限制而拒绝协作的自私性问题,该文从分析数据包源节点与转发节点的收益与开销特性出发,基于虚拟货币的奖励机制,结合博弈理论提出无线自组织网络增强协作模型。该模型将网络协作问题转化为数据包转发路径中多转发节点与源节点收益的博弈均衡问题,在保障双方利益的基础上提出最优的激励方式,促进通信协作的进行。另外,为最大化网络生存时间与避免拥塞,该模型对转发节点的电量与存储空间状态做了相应的约束。更多还原

【Abstract】 In order to solve the selfishness problem that forwarding nodes in the wireless ad hoc network refuse to cooperation due to the limit of energy and storage space, a wireless ad hoc network cooperation enhancement model combined with the game theory is proposed, which is based on the incentive mechanism of virtual currency,analysis the benefit and overhead characteristics of the source nodes and forwarding nodes. In this model, the network cooperation problem is transformed into a game equilibrium problem about the benefit of source node and forwarding nodes in the data forwarding path, promoting the cooperation of communication. Furthermore, in order to avoid the congestion and maximizing network lifetime, the model makes some certain constraint about the energy and storage space for the forwarding nodes.更多还原
