Retrieval Scenario Simulation Results
(server speed is 4 times greater than client speed)
Positive values
indicate better
performance by agents, negative
values indicate better performance by RPC. X
At 0.1 Mb/s, RPC is infeasible at all points so no comparison is possible.
Lessons Learned:
Mobile agents can dramatically reduce total query time when pass ratio is low and bandwidth is low.
Mobile agents can succeed in cases where RPC cannot.
