中文摘要:

这篇文章在端对端的交换子在异构的收音机存取技术(老鼠) 之中为联合收音机资源管理(JRRM ) 作为一条自治途径介绍基因算法(GA ) 可计算的系统。联合会话承认控制(JOSAC ) 和带宽分配作为基因算法的操作与某些明智的修正做的一个特定的决定被联合。建议算法在下列二个条件上被触发。当一个会议被开始时,让会议在最适当的老鼠上宿营并且为需要的服务选择最合适的带宽被触发。当一个会议终止时,通过移交调整进行中的会议的分发也被用来。这将为最好的系统表演增加 JRRM 控制器的调整频率。模拟结果显示建议自治 JRRM 不仅有效地策划移交预定,而且完成很好的还原剂在光谱用途和堵住的概率之间的交易。

英文摘要:

This article presents the genetic algorithm (GA) as an autonomic approach for the joint radio resource management (JRRM) amongst heterogeneous radio access technologies (RATs) in the end-to-end reconfigurable systems. The joint session admission control (JOSAC) and the bandwidth allocation are combined as a specific decision made by the operations of the genetic algorithm with certain advisable modifications. The proposed algorithm is triggered on the following two conditions When a session is initiated, it is triggered for the session to camp on the most appropriate RAT and select the most suitable bandwidth for the desired service. When a session terminates, it is also used to adjust the distribution of the ongoing sessions through the handovers. This will increase the adjustment frequency of the JRRM controller for the best system performance. Simulation results indicate that the proposed autonomic JRRM scheme not only effectively reduces the handover times, but also achieves well trade-off between the spectrum utility and the blocking probability.
