Method and apparatus for directional mesh initialization
A method and apparatus for association in a mesh network may be disclosed. A method in a new node may include performing a discovery procedure with a plurality of peer nodes in the mesh network, initiating a temporary association procedure with each peer node, selecting a set of peer nodes from the plurality of peer nodes based on a selection algorithm at least based on a signal-to-interference and noise ratio (SINR) with each peer node and an interference impact of each peer node, and performing a final association with the selected set of peer nodes.
1. A method for association for a node in a mesh network, the method comprising:
performing a discovery procedure with a plurality of peer nodes in the mesh network;
initiating a temporary association procedure with each peer node;
selecting a set of the peer nodes from the plurality of peer nodes based on a selection algorithm at least based on a signal-to-interference and noise ratio (SINR) with each peer node and an interference impact of each peer node; and
performing a final association with the selected set of peer nodes.
2. The method of claim 1 , wherein the temporary association procedure reserves resources during a beacon response interval (BRI) to allow the node to communication with each peer node.
3. The method of claim 2 , wherein reservation of the BRI prevents collision.
4. The method of claim 1 , wherein the temporary association procedure creates temporary context of the node in each peer node.
5. The method of claim 4 , wherein the node registers with an operation, administration, and maintenance (OAM) center using each peer node on a condition that a peer node is a primary node.
6. The method of claim 4 , wherein the node performs an authentication procedure using each peer node.
7. The method of claim 4 , wherein the node performs SINR-based beam forming with each peer node.
8. The method of claim 1 , wherein the selection algorithm takes into account a signal-to-interference and noise ratio (SINR) of each peer node link, a load on each peer node, a path metric to a gateway, and control slot availability.
9. The method of claim 1 , wherein temporary association with each peer node that is not selected during selection is deleted.
10. The method of claim 1 further comprising receiving a beacon response acknowledgement from the set of peer nodes, wherein the beacon response acknowledgement includes an offset for a next beacon response interval (BRI).
11. A node for association in a mesh network comprising:
an antenna;
a processor, coupled to the antenna, configured to perform a discovery procedure with a plurality of peer nodes in the mesh network;
the processor further configured to initiate a temporary association procedure with each peer node;
the processor further configured to select a set of the peer nodes from the plurality of peer nodes based on a selection algorithm at least based on a signal-to-interference and noise ratio (SINR) with the each peer node and an interference impact of each peer node; and
the processor further configure to perform final association with the selected set of the peer nodes.
12. The node of claim 11 , wherein the temporary association procedure reserves resources during a beacon response interval (BRI) to allow the new node to communication with each peer node.
13. The node of claim 12 , wherein reservation of the BRI prevents collision.
14. The node of claim 11 , wherein the temporary association procedure creates temporary context of the new node in each peer node.
15. The node of claim 14 , wherein the new node registers with an operation, administration, and maintenance (OAM) center using each peer node on a condition that a peer node is a primary node.
16. The node of claim 14 , wherein the new node performs an authentication procedure using each peer node.
17. The node of claim 14 , wherein the new node performs SINR-based beam forming with each peer node.
18. The node of claim 11 , wherein the selection algorithm takes into account a signal-to-interference and noise ratio (SINR) of each peer node link, a load on each peer node, a path metric to a gateway, and control slot availability.
19. The node of claim 11 , wherein temporary association with each peer node that is not selected during selection is deleted.
20. The node of claim 11 , wherein the antenna is further configured to receiving a beacon response acknowledgement from the set of peer nodes includes an offset for a next beacon response interval (BRI).
