Such a situation in a society or an organization leads to violation of social or organizational rules, and at the worst case it suffers from serious accidents or scandals. Therefore, it is important for us to make efforts and take measures to elicit cooperative behaviors. It was demonstrated theoretically that altruism strategy and adaptive prediction and ascertainment strategy are in some cases better than rational strategy under the situation of social dilemma. We built up a mathematical model in order to examine how the probability of correctly predicting and ascertaining the behavior （cooperation or defection） of opponents and the mixture of （a） altruism （all cooperation） strategy, （b） individualism （all defection） strategy, and （c） adaptive prediction and ascertainment strategy affected the expected profit. Simulation results showed that the tit-for-tat strategy was better than the rational （individualism） strategy when the probability of correctly predicting and ascertaining defection of the opponent was considerably higher. As an application of the basic study above, it was explored, using a simulation method, how such a system as opening reputation or peer review in public could work satisfactorily to prevent defective behaviors in auction dealing. The result showed that the information on the handle name and the reputation effectively worked to prevent defective behaviors.展开更多

In order to improve its performance, we present a tradeoff between bandwidth and energy con- sumption in the loT in this paper. A service providing model is built to find the relation- ship between bandwidth and energy consump- tion using a cooperative differential game mo- del. The game solution is gotten in the condi- tion of grand coalition, feedback Nash equili- brium and intermediate coalitions and an allo- cation policy is obtain by Shapley theory. The results are shown as follows. Firstly, the per- formance of IoT decreases with the increasing of bandwidth cost or with the decreasing of en- ergy cost; secondly, all the nodes in the IoT com- posing a grand coalition can save bandwidth and energy consumption; thirdly, when the fac- tors of bandwidth cost and energy cost are eq- ual, the obtained number of provided services is an optimised value which is the trade-off between energy and bandwidth consumption.展开更多

However, the development and application of CDN are limited by some reasons, like operating system and price of ISP. In addition, ISP is suffering network congestion brought by the sudden traffic migration and infrastructure deployment of CDN without the confusion of the basic information of the network. We should balance or coordinate the relationship between ISP and CDN. And the friendliness building of CDN and ISPs will promote the user experience, effectively guarantee their service quality, improve the network operation, and reduce the content distribution cost. In this paper, we discuss the basic working principle of CDN and ISP, analyze possibility of cooperation between CDN and ISP and conclude the existing methods from a novel angle. Furthermore, some suggestions for further research and solutions in this field are provided.展开更多

The successful cooperation bases on its management and operation. Establishing and perfecting the relevant laws and regulations and the inspection appraisal system can ensure the cooperation go smoothly. The government should coordinate the relationship among the government functional departments, colleges and enterprises, clarify the dominant and main body status of college-enterprise cooperation, improve the initiative and enthusiasm of all parties, as to ensure the coordinated development of college-enterprise cooperation. The old system,mechanism and conventions should be broken to promote talents＇ cooperation.
