Comment (by rchokshi):

 The transmission of beacons at all times is by design. We had agreed
 originally that the MP as well as the MPP will always transmit mesh
 beacons. This is mainly to advertise the existence of mesh network to the
 new nodes that have just been booted up and looking for mesh networks
 around them. There are two ways to resolve this and we can do both:

 1. We can disable the beacon transmission in the MPP mode but this
 basically means that the new nodes that discover the mesh networks will
 not get to know if there is a mesh network around them unless they do an
 active scan. We can also disable beacons for MPs as well and, MP neighbors
 can be found with active scan.

 2. We can have a completely separate mode of operation which is that of a
 legacy STA (station) according to the 802.11 parlance. There will be no
 notion of mesh or MPP in this mode and the node will not transmit beacons.
 It will only be able to associate to an Access point or join an *adhoc*
 (not mesh) network. This would be more of a drastic, difficult and time-
 consuming change in software. Hence, this can be planned for later.

 In both cases, the average power consumption of the node (either an MPP in
 case 1 or a legacy STA in case 2) will be lower.
