摘要
在城市交通环境中,车辆安全驾驶问题日益严重,不同的车辆属于不同的私人用户,因此,在车辆行驶过程中就呈现出不同的自私性,自私性超过一定界限后会严重影响车载自组织网络通信。在车载网络环境恶劣的情况下,从车辆主观方面进行研究,设计并实现基于时间惩罚机制的激励机制,促使网络中的自私节点积极参与合作,提高网络投递率,改善网络环境。通过实验,从包的投递率和自私节点比例两个方面来验证机制的有效性和可行性。
In urban traffic environment, the vehicle driving safety problem is increasingly seriously. Different vehicles belong to different private users, therefore, to some extents, presenting different selfish during the vehicle driving and selfish exceeding a certain limit will seriously affect the vehicular Ad Hoc network communication. In vehicle network under the bad environment, from the subjective aspects of vehi- cle, carries on the research on the design and implementation of incentive mechanism of time based on punishment mechanism, makes network of selfish nodes to participate actively in the cooperation, improves the network packet delivery ratio and the network environ- ment. Through the experiment, the validity of the mechanism and feasibility are validated from the two aspects of delivery rate packet and selfish nodes ratio.
