Conclusions and Future Work
–Goal:
facilitate design, implementation and deployment of new and innovative PCS services (resource-intense,
multi-medial)
nemphasis on transparently overcoming resource
limitations and variances in available
resources (power, bandwidth, memory, CPU speed)
nresource variations exist during executions as well as
between executions (cellphone vs. PDAs vs.
laptop)
nexplore mobile code as unifying framework to investigate
resource tradeoffs
–Open
issues:
ncollecting link bandwidth
ncosts of migration/handoff
–use of
hysteresis similar to location mgmt in cellular networks
nload balancing between client and proxy (under way)
ninclude WinCE or Palms (necessitates new mobile code
toolkit)
ncomparison to “traditional” approaches, active
networks
nscalability to provincial or country-wide deployment:
simulation
