What protocol can we use ?
LORA
Antenna
6LoPan
• Too chatty• Node is tied to a gateway• Very difficult mobility support• No security at MAC level

LoRaWAN
• Close ALIGNMENT WITH IEEE 802.15.4 in order to preserve higher layers• But seamless mobility , no handover• Minimal protocol overhead

LoRaWAN design objectives• Designed for virtualized CLOUD BASED network layer:
• Simpler base stations, less maintenance• All NW antennas behave as one, no handover necessary.
• Close ALIGNMENT WITH IEEE 802.15.4 in order to preserve higher layers• 6LoWPAN compatibility• IEEE sensor address space
• MINIMAL ENERGY REQUIREMENTS: Eliminate useless overheads.• Enables SMOOTH VERSIONING

Roaming..
• So roaming includes many different scenarios• Clever roaming implies being connected to several network simultaneously
• Roaming is a back‐end interface problem to solve

Roaming..
• Roaming is about finding a solution to:• Back‐end to back‐end secure connection• Operator to operator clearing & billing• Localizing the end‐devices• Transparent device provisioning across multiple networks
