干扰状态下大规模网络数据流的分发协调技术研究

干扰状态下大规模网络数据流具有实时性、波动性、突发性等特点,当前数据流分发协调方法无法保证数据流的平稳传输及分发协调的实时性。为此,提出一种新的干扰状态下大规模网络数据流分发协调方法,通过网络数据流预测值和实际值之间的误差滤除干扰状态下的干扰数据,保证剩余数据流的纯正性。将大规模网络数据流分发协调问题转换成多目标优化问题,以提高大规模网络数据流分发协调的整体性能为目的设定一个目标函数,提出一种大规模网络数据流分发协调预测技术,通过比较处理器计算资源和未来的预期负载确定数据流分发协调策略。实验结果表明,采用所提方法对干扰状态下大规模网络数据流进行分发协调,不仅效率高、实时性好,而且CPU资源利用率很高。     

Optimization in the Migration Problem of Mobile Agents in Distributed Information Retrieval Systems

In this paper,we employ genetic algorithms to solve the migration problem (MP).We propose a new encoding scheme to represent trees,which is composed of two parts;the pre-ordered traversal sequence of tree vertices and the children number sequence of corresponding tree vertices.The proposed encoding scheme has the advantages of simplicity for encoding and decoding,ease for GA operations,and better equilibrium between exploration and exploitation.It is also adaptive in that,with few restrictions on the length of code,it can be freely lengthened or shortened according to the characteristics of the problem space.Furthermore,the encoding scheme is highly applicable to the degreeconstrained minimum spanning tree problem because it also contains the degree information of each node.The simulation results demonstrate the higher performance of our algorithm,with fast convergence to the optima or sub-optima on various problem sizes.Comparing with the binary string encoding of vertices,when the problem size is large,our algorithm runs remarkably faster with comparable search capability.
