On Sept. 20, Welles transmitted a reply to Preble: "Upon submitting your letter to the President, I received from him prompt directions to announce to you your dismissal from the service".
If no node transmits a reply in a given slot, the slot is called empty slot.
Thus, the receiver node b transmits a REPLY message with probability P A ; otherwise, it returns to idle state.
Secondary radar, in addition to primary radar characteristics, uses a transponder on the target for responding to interrogation by transmitting a coded reply signal.
Using the short-range radio interface, the main nodes transmit a query to ancillary nodes, and those nodes that receive the query reply with an acknowledgement, becoming candidate cooperating nodes.
If a node decides to transmit a HELLO message in a slot, it does so in the first mini-slot and listens to the channel for any REPLY message(s) from its neighboring node(s).
People transmit a variety of signals.
Sliding window protocol, available in MS-DOS Kermit 3.0, C-Kermit 5A, and in PRIME Kermit, does not stop and wait for a reply after transmitting a packet, but rather transmits packets continuously and permits the acknowledgements to come later.
For instance, for two-hops, the responder receives the synchronization request from a petitioner, and instead of sending back the synchronization reply, it transmits a synchronization request to the next node in the path toward the destination, adding one more hop.
Then U a transmits the reply message { M 6 a, M 7 a } to C i. On receiving { M 6 a, M 7 a }, the user C i first obtains the random number R sa by computing M 8 = M 6 a ⊕ M 1, where M 1 = h (ID i || x s ).
When S starts to transmit the reply messages, it selects the nearest requestor (e.g., A 1) from the address list as the destination and transmits the packet using improved GPSR algorithm.
