Hi,
      I have some simple questions about 802.11 MAC layer and Hello
messages in routing protocols:
      (1) Access Points periodically broadcast MAC beacon signal, is it
the same for mobile nodes in ad-hoc mode?
      (2) If not, in AODV draft, it seems only the nodes along active
paths broadcast Hello messages and other nodes don't. In DSR draft, no
Hello messages are specified at all. Then how is neighbor detection
mechanism implemented in MANET?
       Thank you in advance.
