Hi, I have mobile machines that need to “broadcast” their state to any other mobile machines that can hear them.
No forwarding or routing is required, just that the machines hear each other when the radios are within range.
It would also be desirable if there is an access point, that the router board could also connect to the network while the other adhoc communication goes on.
Here’s what I was thinking about:
-Routerboard with 1 ethernet port and 2 radios that are a/b/g
-Radio #1 is setup as a normal client, say 802.11b (so 2.4GHz) client and scanning any channel of the 13 channels for an AP
-Radio #2 is setup to use 802.11a (so 5.2 GHz) on channel 48 in ??? mode.
-My software sends Ethernet broadcast frames (not using IP) and fills the ethernet frame with the machine state data.
this ethernet frame enters the routerboard through the wired ethernet port and is being repeated by radio #2
-Broadcast ethernet frames received by Radio #2 are forwarded and repeated onto the wired which are then picked up by my software.
Would that be possible?
Is there a better way to achieve what I want in a more standard way (say adhod networking using IP broadcast) ?
Thank you,
Martin Politick.
