摘　　要：对于移动代理系统中的孤儿处理问题,通常的研究主要集中在中间过程,即检测和终止上.实现的方法中需要改变代理间的对等关系,这增加了通讯成本及系统的复杂性.提出了一种基于委托模型的孤儿处理算法,根据委托合作策略,可以创建接收者代理组,进而把对孤儿问题的处理从对中间过程的控制转为对发起者和接收者代理组之间关系的控制.实验表明,在相同的测试环境下该算法比阴影算法更有效地减少了孤儿出现的比率.For the orphan-handling problem in mobile intermediate processes namely detection and termination. agent systems, research mainly focuses on the This usually changes the equity relation among the agents, and consequently increases communication cost and system complexity. An orphan-handling algorithm based on the delegation model was proposed. The agent group of receivers could be built based on delegation cooperation tactics. And thus, the orphan the intermediate processes to controlling the relation -handling problem were transformed from controlling between the agent groups of receivers and the agent groups of senders. The experiments show that the algorithm is more effective than the shadow algorithm in reducing the occurrence of orphans under the same experimental conditions.
