项目摘要
The objective of this research project is to investigate the base stations location problem and the dynamic channel assignment problem in cellular mobile communication systems. In this research, it is assunmed that each cell has different traffic intebsity, different shape and different area from each other. The research of this projct is summarized as follows ;(1) It is proved that the base stations location problem is intractable ;(2) An approximate algorithm, based on the genetic algorithm, for the base stations location problem is proposed ;(3) The solution obtained by the approximate algorithm for the base stations location prblem is good approximation to the opotimum solution for the base stations location problem ;(4)It is possible to model dynamic channel assignment algorthms by using Clique Packing in cellular systems where the traffic distribution is heterogeneous ;(5) It is possible to analyze the communication traffic characteristics of dynamic channel assignment algorithms on the Clique Packing model under the non uniform traffic distribution ;(6) A method for analyzing the communication traffic characteristics of cellular systems using Dynamic Channel Assignment is proposed. using this method, we can consider the effect of mobility of subscribers to mobile communication systems on the traffic characteristics. It is shown that this method is effective on the analysis.These results contribute to balancing the quality of service in cellular systems where the traffic intensity is not uniform and the efficient use of frequency bands. Also, the results are applicable to optimum design of cellular mobile communication systems.We consider that flexibility is important to adapt mobile communication systems to various kinds of service in the future and multi-hop connection is one way to add flexibility to the system.
本研究计画的目的是探讨蜂巢式移动的通讯系统中的基地台定位问题与动态频道分配问题。在本研究中,假设每个小区具有不同的交通密度、形状和面积。(1)证明了基站选址问题是一个难处理的问题,(2)提出了一种基于遗传算法的基站选址问题的近似算法,(3)用近似算法得到的基站选址问题的解是基站选址问题最优解的很好逼近,(4)用遗传算法得到的基站选址问题最优解是基站选址问题最优解的近似解。(4)在业务量分布不均匀的蜂窝系统中,利用团包装模型对动态信道分配算法进行建模是可能的:(5)在业务量分布不均匀的蜂窝系统中,利用团包装模型对动态信道分配算法的业务量特性进行分析是可能的;(6)提出了一种基于动态信道分配的蜂窝系统业务特性分析方法。使用这种方法,我们可以考虑移动的通信系统用户的移动性对业务特性的影响。分析结果表明,该方法是有效的,这些结果有助于在业务强度不均匀的蜂窝系统中平衡服务质量和有效利用频带。我们认为,灵活性对于未来移动的通信系统适应各种业务非常重要,而多跳连接是增加系统灵活性的一种方法。
