A sends an acknowledgment response, verifying that data can be transferred in both directions.
When B receives each packet, it sends an acknowledgment, or an ack, to A, that the packet arrived.
After the reception of this packet, the root node sends an acknowledgment back to finish the synchronization process.
At the ACK subslot, the receiving MS sends an acknowledgment to the BS and RS to inform the state of the packet.
Afterwards, the consumer submits a bind and invoke service request to the chosen SP, which in response sends an acknowledgment and grants access to the consumer.
After the reception of the packet, the receiving node sends an acknowledgment packet to the transmitter if the node failed to receive the packet.
The agreement on the part of the bundle that is successfully transferred is done using the following method: the server sends a bundle by blocks, and at the end of each block, an acknowledgment is sent to the client that confirms its reception, sending an acknowledgment to the server.
respectively, where X s denotes the source signal transmitted at a power P. Each of K relays receives the source packet, and will send back an ACKnowledgment (ACK) or NACK packet immediately, if it succeeds or fails to decode the packet.
Setting a transmission "window," TCP determines the number of bits that can be sent before an acknowledgment of their receipt is required as an okay to send additional bits.
If D receives the packet in this phase correctly, then it sends back an acknowledgment (ACK) and R just idles.
Acting like the root node in level 0, a level 1 node sends back an acknowledgment, the process continues until all the nodes at different levels are synchronized, and the entire network becomes synchronized.
