项目摘要

(1) Call Admission Control in Mobile Communication NetworksWe have proposed a new call admission control (CAC) scheme for voice calls in mobile communication networks with voice and data traffic, on the basis of the theory for semi-Markov decision processes. Our optimal policy restricts new voice calls in order to minimize the total expected costs (blocking and forced termination probabilities) over a long term.(2) Performance Analysis of the IEEE 1394 Serial Bus InterfaceThe IEEE 1394 interface allows both isochronous transfer mode for real-time applications and asynchronous transfer mode for delay-insensitive applications. We have proposed and analyzed a queueing model to evaluate the waiting time of asynchronous packets affected by the isochronous traffic.(3) Optimal Wavelength Converter Placement in Optical NetworksIn optical networks, wavelength converters are required to improve the efficiency of wavelength division multiplexing. We have developed a genetic algorithm to determine the optimal locations of the nodes equipped with converters. Our algorithm has been applied to realistic networks constructed from the locations of NTT offices in Ibaraki and Kanto areas.(4) Analysis of Queueing ModelsUsing the theory of applied stochastic processes, we have studied several queueing models.

（1）移动通信网络中的呼叫录取控制已根据半马多夫决策过程的理论，提出了一种带有语音和数据流量的移动通信网络中语音呼叫的新呼叫录取控制（CAC）方案。我们的最佳政策限制了新的语音呼叫，以最大程度地减少长期的预期成本（阻止和强制终止概率）。（2）IEEE 1394串行总线IEEEE 1394 IEEE 1394接口的性能分析允许相同的传输模式用于实时应用程序，并允许用于实时传输模式进行延迟启用应用程序。我们已经提出并分析了一个排队模型，以评估受等量流量影响的异步数据包的等待时间。（3）在光学网络光网络中，最佳波长转换器位置，需要波长转换器以提高波长的效率波长的效率。我们已经开发了一种遗传算法，以确定配备转换器的节点的最佳位置。我们的算法已应用于由Ibaraki和Kanto地区NTT办公室位置构建的现实网络。（4）我们研究了几个排队模型的排队模型的分析，分析了排队模型。
