Abstract

A method discovers neighboring nodes in a wireless network of nodes. The nodes include a set of concentrators acting as IPv6 routers and a set of sensor nodes acting as IPv6 hosts. The sensor nodes can also act as relay nodes. In each node, a 64-bit interface ID is configured using a 48-bit MAC address. In each node, a unique IPv6 link-local address is configured using the 64-bit interface ID. In each node, the neighboring nodes are discovered by transmitting unsolicited Neighbor Advertisement (NA) messages. A Router Advertisement (RA) messages is distributed from the concentrators to the sensor nodes meters by using the relay nodes. In each node, a unique IPv6 address is configured and registered at the concentrators by using the relay nodes.

Dependent claims

A method for discovering neighboring nodes in a wireless network of nodes, wherein the nodes include a set of concentrators acting as IPv6 routers and a set of sensor nodes acting as IPv6 hosts, and wherein any of the sensor nodes can act as relay nodes, comprising the steps of:

configuring, in each node, a 64-bit interface ID using a 48-bit MAC address;
configuring, in each node, a unique IPv6 link-local address using the 64-bit interface ID;
discovering, in each node, the neighboring nodes by transmitting unsolicited Neighbor Advertisement (NA) messages;
distributing a Router Advertisement (RA) messages from the concentrators to the sensor nodes using the relay nodes;
configuring, in each node, a unique IPv6 address;
and
registering the unique IPv6 address of each sensor node at the concentrators by using the relay nodes.
