Abstract
This paper presents a comparative analysis of Remote Method Invocation (RMI) and Mobile
Agent (MA) paradigm used to implement the information storage and retrieval system in a distributed
computing environment.
Simulation program was developed to measure the performance of MA and RMI using object
oriented programming language (the following parameters: search time, fault tolerance and invocation
cost. We used search time, fault tolerance and invocation cost as performance parameters
in this research work.
Experimental results showed 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. Finally MA has a better fault tolerance than the RMI. With a probability of failure pr
= 0.1, mobile agent degrades gracefully.
