Goal
• Integrate your sensor network with the Internet, so that:– Every mote is “just another host” on the Internet;– You can interact with your sensor network from
any computer on the Internet.

Outline
• How do I build a bridge between my sensor network and the Internet?
• How can my laptop interact with an IPv6-ready WSN?

Bridging Internet and motes
• Low-power Border Router is connected to:
– the Internet (e.g. Ethernet)– a mote
• Mote appears like a layer 2 interface:
– Configure mote’s IPv6 address– Activate IP forwarding– Bridging happens at layer 3
HTTP, XML, OpenADR
TCP, UDP
IPv6
Ethernet IEEE802.15.4e
CAT5 twisted pair IEEE802.15.4-2006

Distributing IPv6 Prefix to motes
• Neighbor Discovery– RFC2461 (6LoWPAN-ND-11 draft, to some extent)
• Router Solicitation (ICMPv6 type 133)• Router Advertisement (ICMPv6 type 134)• Neighbor Solicitation (ICMPv6 type 135)• Neighbor Advertisement (ICMPv6 type 136)• Redirect Message (ICMPv6 type 137)
• Router Advertisement Options– Can contain 6LoPWAN IPHC-07 contexts– Can contain Prefix information
• Which can be used for Stateless Address Auto-configuration is bit “A” is set
• RADVD is the Linux tool to send Router Advertisements– apt-get install radvd– create /etc/radvd.conf– /etc/init.d/radvd start
interface tun0 { AdvSendAdvert on; MinRtrAdvInterval 10; MaxRtrAdvInterval 20; prefix 2001:470:1f05:dff::/64 { AdvOnLink off; AdvAutonomous on; AdvRouterAddr on; };};

1. Point-to-Point Connectivity
serial
10’s meters indoors
• no infrastructure required• you need extra hardware• you need to be really close

2. IPv6-in-IPv4 tunneling
IPv6
IPv4
you establish a tunnel
tunnel server(Hurricane
Electric)
• transparent for your application• you need to set up the tunnel

your router establishes the tunnel
(workshop configuration)
• the easiest solution for you• the hardest solution for your network admin

4. IPv6-to-IPv4 proxying
IPv6Proxy server
• you do not need an IPv46address
• no firewall issues• not transparent for the software• if you want to add traffic type,
you need to update the proxy
