[Madwifi-devel] integrating sectorised antenna with a Wi-Fi node

[Mofolo Mofolo]

Hi,

I am integrating sectorised antenna with a Wi-Fi node, basically a PC
running Ubuntu. The network network is setup on ad-hoc
mode. Currently installed driver is MADWIFI

Please advise on how can a node perform neighbor discovery while using
sectorised antennas. That means for every station in a neighbor's table, an
appropriate antenna sector has to be recorded so as for
every packet transmitted, the node can select and use suitable antenna
sector.

For example:

If we say each node is equipped with an antenna with 4 sectors, then the
node has to determine which sector to use when communicating
with neighbors. in the case where nodes A, B, C and D are aligned in a
straight line; node 'B' has to use a different antenna sector when
communicating with node 'A', as opposed to when communicating to node 'C'.

A B C D


How can this mapping of neigbouring nodes with specific antenna sectors be
achieved, if maybe RSSI is used as the determining factor during building
up of neighbor's table?

Thanks.
