Fault Tolerance Mobile Agent execution System (FTMAS) modeling and performance analysis

摘要

Mobile Agent paradigm is said to give better performance advantages over other paradigms due to its features especially in the network and the internet applications. To integrate mobile agents into such applications, fault tolerant ability of an agent is one of the most important issues. The paper analyzes the Fault Tolerant Mobile Agent execution System “FTMAS” model proposed in [1] and studies the performance mathematically. The paper defines and analyzes the migration time MT, the Round trip time RTT, the transfer time TrT and the system throughput Thr. They are tested against 3 performance metrics: the average connectivity of the network, the agent size and the probability of failure. The performance analysis proves that our proposed FTMAS is a promising model in the fault tolerant field of the mobile agent MA execution.
