ACP——一种基于局部邮区的移动agent通信算法

ACP——A Local Post Area Based Mobile Agent Communication Algorithm

agent的迁移在位置透明性、通信可靠性以及迁移和执行的异步性等多方面对通信算法的设计提出了挑战 提出一种基于局部邮区的移动agent通信算法 ,通过在agent当前通信和迁移活动较集中的区域建立局部邮区来支持消息的高效传输 ,且通过对邮区迁移和消息发送的同步来保证通信的可靠性 此外 ,算法支持通信的位置透明性 ,对Home结点依赖少 ,对agent迁移不做限制 。

Agents' migration presents challenges to the design of communication algorithm in aspects like location transparency, communication reliability and asynchrony of migration and execution. A new algorithm based on local post area is proposed in this paper. It can reduce communication cost greatly by setting up a post area in the region where the target agent's migration and communication activities are frequent. The algorithm can overcome message loss by synchronizing. It can also provide location transparency, reduce the reliance on agent's home and eliminate the constraint on agent's migration. In addition, it has a good support for adaptability and fault tolerance.
