在本文中,我们处理一个动态和随机的接纳控制和移动的关联问题,在异构无线网络。我们扩展通常的问题,通过添加移动功能描述的马尔可夫调制泊松过程。目的是优化系统的平均性能。这个动态控制问题的建模和解决使用半马尔可夫决策过程(SMDP)的框架。然后,我们评估的移动性的影响,并表明(i)我们的网络为中心的方法优于一个简单的以用户为中心的算法和(ii)移动性提高了系统的性能时,使用的问题的最佳策略。
In this paper, we deal with a dynamic and stochastic admission control and mobile association problem in an heterogeneous wireless network. We extend the usual problem by adding mobility features described by a Markov Modulated Poisson Process. The aim is to optimize the average performance of the system. This dynamic control problem is modeled and solved using a Semi Markov Decision Process (SMDP) framework. We then assess the impact of the mobility and show that (i) our network centric approach outperforms a simple user centric algorithm and (ii) mobility improves the performance of the system when optimal policy of the problem is used.
