Project Description

W5100 is used for Gateway node of 6LoWPAN system. This product is made by libelium.

Currently IBM and Libelium have joined efforts to offer a unique IPv6 development platform for sensor networks and the Internet of Things (IoT). By integrating the IBM Mote Runner SDK on top of Libelium Waspmote sensor platform we get a unique and powerful tool for developers and researchers interested in 6LoWPAN / IPv6 connectivity for the Internet of Things.

» Node Types

  • End Node : These nodes have sensors integrated and are used to gather the information and send to the GW. They create a mesh network among them, forwarding the packets of other nodes in order to make the information reach the GW. Each End Node is equipped with a 6LoWPAN radio, sensors and a battery.
  • Gateway (GW) : This node takes the information sent by the End Nodes and send it to the Tunnelling IPv4 / IPv6 server by using the Ethernet IPv4 interface. Each GW Node is equipped with a 6LoWPAN radio and a Ethernet interface and a battery.

» Network Topology

In the diagram below we can see how the Waspmote Mote Runner 6LoWPAN / IPv6 Network works.

  1. The sensor nodes uses the 6LoWPAN protocol over the 802.15.4 link layer to create a mesh network which interconnects any device in the network with the Gateway (GW).
  2. Once the GW takes the 6LoWPAN packets, it changes the IP header to IPv4 while keeping the UDP transport layer.
  3. Then it sends the information to the IPv4 / IPv6 Tunneling machine which will change header to a the proper IPv6 format and will send the information to IPv6 Servers located on the Internet, where users are connected.

* The GW and the Tunneling Machine are intended to be a single device in the future.
