IP Networks vs. IP Networks vs. WSN**

IP Networks WSN

Networking Mode Application-independent

Application-specific

Routing Paradigms Address-centric Data/location-centric

Data Rate High (Mbps) Low (Kbps)

Resource constrains Bandwidth Energy, limited processing and memory

Network Lifetime Long (years-decades) Short (days-monhts)

Operation Administered Self-configured

IPv6 Auto-configuration

Is needed when*:

*Thomson, S., Narten, T., Jinmei, T., “IPv6 Stateless Address Autoconfiguration”, *Thomson, S., Narten, T., Jinmei, T., “IPv6 Stateless Address Autoconfiguration”, draft-ietf-ipv6-rfc2462bis-07, draft-ietf-ipv6-rfc2462bis-07, DecemberDecember 2004; 2004;

The interface is initialized at system startup time.

The interface is reinitialized after a temporary interface failure.

The interface attaches to a link for the first time.

The interface is moved from a Sensor Router spectrum to another.
