If you aren't running it, probably isn't needed.  I mention it only 
because you had used the word 'wireless'.  And there is a patch around 
for hostapd to talk properly to ovs.


I only run OVS on each node; however, it seems that I have to configure 
something to allow nodes to know about the mac address of each other


a quick google for 'manet arp' indicates something like:

https://www.ietf.org/mail-archive/web/manet/current/msg08124.html

So depending upon the devices you have, the bridging/repeater mode of 
your node(2) may have issues.


Maybe a manet mailing list might have an answer?

you may want to have a look into how Mininet-WiFi uses OVS in such
scenarios. There is code to reproduce a number of MANET use cases,
plus an active mailing list (cc:)

In MANET (mobile ad hoc networks), wireless nodes can communicate together
without any access points.
Should I still consider hostapd for each wireless node in my simulation?
I only run OVS on each node; however, it seems that I have to configure
something to allow nodes to know about the mac address of each other
