Abstract :
Presents a mobile agent-based three-tier protocol to improve the data transmission while accessing distributed databases. When a mobile agent is employed to fulfil a distributed query, it has many choices for travelling in the network. The master/slave pattern can be applied to mobile agents on the basis of a centralized two-phase commit (2PC) protocol to allow the parallel execution of mobile agents. In this paper, a three-tier protocol is proposed, which clusters all the slave agents to strengthen the parallelism. This three-tier protocol can significantly weaken the data transmission bottleneck and reduce the response time. This paper describes the protocol and a performance evaluation of it
