摘要
在网络能量优化控制的研究中,针对机会网络中由能量受限引起节点自私性的问题,提出一种基于博弈的能量受限节点的协作激励机制(GEIP),GEIP机制采用"礼尚往来"策略。上述机制结合博弈论知识建模分析节点行为,为节点加入能量等级和容忍度属性。在激励节点协作的同时,容忍个别节点的自私行为,可节约节点能量,延长整个网络的服务寿命。仿真结果表明,上述机制一方面可激励节点进行协作,抑制了节点的自私行为,另一方面节约节点的能量,延长了网络的服务寿命。
According to the selfishness of nodes in opportunistic networks caused by the limited energy, a gaming based energy - constrained incentive protocol (GEIP) was proposed in this paper, which is based on " reciprocity" strategy. It established the analytical model based on a repeated game, and joined energy levels and tolerance proper- ties for nodes. To save the energy of nodes and prolong the service life of the network, GEIP tolerated selfish behavior of nodes. The simulation results show that the GEIP, on one hand, encourages nodes to collaborate and suppresses the selfish behavior of nodes to improve network performance; on the other hand, it reduces the energy consumption of nodes and prolongs the life of the network.
