Different with the well-mixed system, coexistence and extinction emerge alternately in the system, where a ＂zero-one＂ behavior is robust for a small population size, whereas, the system is predominated by coexistence for a big population one. We study in detail the influence about the fluctuation to the change of the state, and find that the difference between the maximal amplitude about the fluctuation and the average intensity determines which state the system is ultimately. In addition, we introduce Ports energy to explain the reason of the ＂zero-one＂ behavior. It is shown that the average Ports energy per site is the distance to the ＂zero-one＂ behavior in the model.展开更多

First, astochastic differential game model is proposed for non-cooperative decentralized uplink power control with a wisdom regulation factor over WA-BodyNets with a onehop star topology.This model aims to minimize the cost associated with the novel payoff function of a player, for which two cost functions are defined： functions of inherent power radiation and accumulated power radiation darmge. Second, the feedback Nash equilibrium solution of the proposed model and the constraint of the Quality of Service （QoS） requirement of the player based on the SIR threshold are derived by solving the Fleming-Bellman-Isaacs partial differential equations. Furthermore, the Markov property of the optimal feedback strategies in this model is verified.The simulation results show that the proposed game model is effective and feasible for controlling the transmitted power of WA-BodyNets.展开更多

When players agree on the need to collaborate but are in conflict regarding the specific method, one player must always compromise. This situation is known as the Battle of the Sexes in game theory. It has ever been believed that if an agreement is reached under such circumstances, the players do not have the incentive to withdraw from the agreement. However, this study shows that this belief is not always true if the players were able to revise the outcome of their negotiations later. The wide-ranging fields use game theories for their analysis frameworks to analyze the success or failure of coordination. However, comparing with the possibility of betrayal illustrated as a well-known Prisoner Dilemma, it has been rare to discuss conflict regarding the specific method of coordination, although such situations are often observed in today＇s interdependent real world. The repeated Battle of the Sexes games presented in this study would be a useful framework to analyze conflict regarding the specific method of coordination.展开更多
