Simulating Autonomous Mobile Programs on Networks

Executive Summary

Autonomous Mobile Programs (AMPs) have been proposed for load management in dynamic networks. An AMP is aware of its resource needs and periodically seeks a better location in the network to reduce execution time. AMPs have previously been measured using mobile Java Voyager on Local Area Networks (LANs). The authors have constructed a simulation model of AMPs and reproduced 4 sets of experiments on homogeneous networks, i.e. networks where all locations have the same processor speed, and 2 sets of experiments on heterogeneous networks with collection of large and small AMPs. The results show that simulated collections of AMPs obtain similar balanced states to those reached in the real experiments, and have only minor differences from real experimental results.
