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
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?
