Overall looks good with some minor nits.

Major issues:

Minor issues:

Nits/editorial comments:

In section 1.2,
"These slots are rare, and with 10ms
   slots, with a slot-frame length of 100, there may be only 1 slot/s
   for the beacon."

IMO, this could be reworded to increase clarity. For example, "Considering 10ms
slots and a slot-frame length of 100, these slots are rare and could result in
only 1 slot for a beacon."

In section 1.3,
"At layer 3, [RFC4861] defines a mechanism by which nodes learn about
   routers by listening for multicasted Router Advertisements (RA)."

Would it be possible to reword to not use "multicasted?"  For example,
"by receiving multicast Router Advertisements (RA)."

"no RA is heard within a set time, then a Router Solicitation (RS) may
   be multicast,"

"may be sent as multicast" might be more clear.

In section 2,
"proxy priority  this field indicates the willingness fo the sender to
      act as join proxy.  Lower value indicates greater willingness"

Typo "fo"

IMO, it would be clearer if the field name in the protocol header
matches the description for it. For example, "Proxy priority (proxy prio)"

In Section 4,
"An interloper with a radio sniffer would be able to use the network
   ID to map out the extend of the mesh network."

extend or extent?
