What is 6LoWPAN?• Acronym for IPv6 over Low power Wireless Personal Area Networks.
• Standard from the maker of Internet (IETF) which works with existing Internet infrastructure (30+ years)
• Widely accepted Standard and created Internet based on IP architecture
• It provides
• Adaptation layer for interoperability and packet formats
• Adapting the packet sizes of the two networks
• Address resolution
• Addressing management mechanisms
• Routing considerations and protocols for mesh topologies in 6LoWPAN
• Scalable
Internet of Things Group
What is NetContiki?
• Fork of Contiki OS
• Numerous Bug fixed in Contiki OS and other components (eg. CoAP) with optimization towards commercialization
• Features and tools
• Interoperable IPSO 6LoWPAN stack
• Automatic channel selection
• Over the air upgrade
• Optimization in mesh routing
• Security framework
• Scalable to have larger network per routing device
