  • I am looking for clarification on routing in wireless networks, and am specifically interested in the overhead in wds vs. ad-hoc networks, and how far up the protocol stack packets will travel that aren't intended for that particular router.

    For WDS, I believe that each wds link will have its own L2 table of clients that are attached to that AP, but I am not seeing the difference between using WDS and Ad-Hoc, if each wireless router will be receiving the frames because of the nature of how the antennas are aimed in a mesh environment, (to allow all radios see eachother), and will hence be using CSMA/CA.

    Is there any benefit to using WDS vs. Ad-Hoc in a pure mesh environment?

    Is there any benefit to using WDS vs. Ad-Hoc where there is hidden nodes?

    Thanks,

  • Hi Omni:

    Your question prompted me to check on progress made for an IEEE mesh standard.
