摘要

对于一类利用中心式构架和分布式构架各自优点的分层非结构化P2P系统, 通过定义一种Markov切换空间模型来描述其动态组划分切换行为, 从而导出相应的系统性能优化问题. 同时还在Markov决策过程理论的基础上给出了关于性能指标的参数化梯度优化算法, 并通过相应的实例仿真验证了算法的有效性.

Abstract

For a class of hierarchical unstructured P2P systems, a Markov switching-space model is introduced to describe their behavior of dynamic grouping. It is also formulated as a optimization problem based on Markov decision processes. Also parameterized gradient algorithm is provided to optimize the performance, followed by the corresponding simulations and discussions.
