Performance evolution of java remote method invocation and mobile agent techniques in context of Distributed Environment

A mobile agent is a program that is not bound to the system on which it began execution, but rather travels amongst the hosts in the network with its code and current execution state (i.e. Distributed Environment). The Mobile Agent technology is emerging as an alternative to build a smart generation of highly distributed systems. In this work, we investigate the performance aspect of agent-based technologies for information retrieval. We present a comparative performance evaluation model of Mobile Agents versus remote Method Invocation by means of an analytical approach. A quantitative measurements are performed to compare Java RMI and mobile agents using communication time, code size (agent code), Data size, number of node as performance parameters in this research work. The results depict that Mobile Agent paradigm offers a superior performance compared to RMI paradigm, offers fast computational speed; procure lower invocation cost by making local invocations instead of remote invocations over the network, thereby reducing network bandwidth.
