Abstract: To improve the connectivity of Mobile Ad Hoc Network(MANET) and Internet when the resources are limited, this paper introduces a repeated-game model on dynamic gateways and in turn establishes an incentive-compatible condition. Considering the future profit dynamic gateways will voluntarily take forwarding due to the overawing of punishment mechanism. Simulation result indicates that when the parameter setting is rational, the forwarding degree of dynamic gateways will obviously advance, which enhances Internet connectivity for MANET.

摘要： 针对资源受限情况下移动自组网与Internet的互联问题，提出在动态网关上建立重复博弈模型。该模型通过一个激励一致性条件使动态网关考虑将来的利益，迫于惩戒机制而自愿参与转发协作。模拟结果表明，通过合理设置参数能有效提高动态网关的转发协作程度，实现移动自组网与Internet高效稳定的互联。
