Integration of 6lowpan networks
• The integration of 6lowpan networks with the
Internet and wireless infrastructure networks
increases the network capacity, coverage area
and application domains.
• We provide various integration scenarios and
discuss associated issues with such
deployments.
• Work was funded by DoD project: “IPv6 Support
for Net-Centric Operations Warfare”
Scenario 1
• Goal: To monitor an area using a set of networked
sensors.
• Sensor Network is deployed in a remote area (No
direct connectivity to the outside world)
• An end user monitors the situation.

Scenario 2
Network A
• Unlike the previous scenario, the Sensor
Network can be physically moving.

Conclusion
• 6LoWPAN networks may be deployed remotely
in non-traditional scenarios.
• The IP layer has new requirements to be able to
provide access to these 6LoWPAN networks via
changing access networks and to do so in a
secure manner.
• The usage of SeND and NEMO protocols allows
6LoWPAN networks to be fully integrated into a
dynamic mobile hetergenous network for
ensuring global reachability to the individual
6LoWPAN nodes.
