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.
