摘要
论述自主通信的基本组成和功能,将自主通信系统看成一个由采集、分析、判决和动作行为4个单元组成的特殊反馈控制系统,着重分析判决单元。基于QoS研究一种多控制变量、多观测变量马尔可夫最优判决策略。仿真结果表明,采用马尔可夫最优判决策略可以提高系统自适应网络环境变化的能力。
The components and functions of autonomic communication systems are described, and it can be viewed as a special kind of feedback control systems with the elements of collecting, decision, analyzer and actuator. This paper focuses on the decision-element. The decision-element uses optimal policies based on QoS with Markov Decision Process（MDP）, which seekes to satisfy a set of system QoS. Simulation results show that communication system adaptation can be guided by decision rules based on QoS found by the methods of MDP, when there are multiple controlled features and multiple system measures used to drive the decisions.
