摘要:

我们考虑利他行为对随机介质访问控制(时隙ALOHA)的局域通信网络的影响。对于一个理想化的,同步迭代的,两个玩家的游戏与不对称的球员的需求,我们发现一个哈密顿量下的纯粹利他行为的Jacobi动力学。虽然内部纳什均衡点的位置不改变利他行为的存在,其局部渐近稳定的性质。存在一个局部利他行为区域,在该区域内,两个内部纳什均衡点都不是局部渐近稳定的。此外,对于一个单一的纳什均衡的权力控制游戏,我们展示了它的稳定性如何变化的函数的利他主义参数。这些利他主义的游戏框架的变化进行了讨论,考虑功率(而不是吞吐量)为基础的成本和线性效用函数。

英文摘要:

We consider the effects of altruistic behavior on random medium access control (slotted ALOHA) for local area communication networks. For an idealized, synchronously iterative, two-player game with asymmetric player demands, we find a Hamiltonian governing the Jacobi dynamics under purely altruistic behavior. Though the positions of the interior Nash equilibrium points do not change in the presence of altruistic behavior, the nature of their local asymptotic stability does. There is a region of partially altruistic behavior for which neither interior Nash equilibrium point is locally asymptotically stable. Also, for a power control game with a single Nash equilibrium, we show how its stability changes as a function of the altruism parameter. Variations of these altruistic game frameworks are discussed considering power (instead of throughput) based costs and linear utility functions.
