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

Why 6LoWPAN and what are the possibilities?
Key advantages
1. It is an Internet Protocol (IPv6/IPv4)
technology which works seamlessly with
existing network infrastructure
2. It works with existing software infrastructure
such as firewall and network management
