IP-USN Router is 6LoWPAN gateway defined in 6LoWPAN. It interconnects wireless sensor network to the Internet. IP-USN router is responsible for propagating IPv6 prefixes to the sensor nodes which are communicating within the router’s area. Whenever sensor nodes tries to communicate to the hosts behind IP-USN router, the router recognizes 6LoWPAN packets from sensor nodes and with it’s adaptation layer built in, converts the packets which are accepted from the IPv6 hosts In general, IP-USN router minimizes gateway overhead by performing only the packet processing. Peer-to-peer nature of the Internet is guaranteed among host-to-node or node-to-node are available with the deployment of IP-USN router iBIT IP-USN router seamlessly interconnects IPv6 network and 6LoWPAN over IEEE 802.15.4. All the management servers can talk directly to the sensor nodes with just IPv6 protocols through IP-USN router
