Sentence examples for buffer in the relay from inspiring English sources

Recently, it has been shown that using buffer in the relay node can improve the system throughput [8 11].

Using buffer in the relay improves the system throughput, and therefore, it reduces the average end-to-end packet delay.

The data admitted into a BS buffer are queued until transmission to the corresponding direct user, or to the corresponding buffer in the relay serving the user.

Finally, based on intuitive reasoning for general scenarios, we have concluded that employing buffer in the relay improves both the system's throughput and average end-to-end packet delay.

In the case of conventional relaying (no buffer in the relay), only when c 1 c 2=G G, the scheduler notifies the BS to transmit a packet in the first subslot.

Using numerical results, we have verified our analysis and discussions, and shown that using buffer in the relay leads to higher system throughput and lower average end-to-end packet delay.

On the other hand, the minimum possible end-to-end packet delay in both of the relaying systems is one time slot, which happens when there is no queue neither in the BS buffer nor in the relay buffer; in such a case, when a packet arrives at the BS, it can be immediately transmitted to the relay and then, the relay can immediately transmit it to the destination.

This is reasonable as the CSI is assumed to be available at the scheduler, irrespective of exploiting buffer or not in the relay, and using it can prevent information loss in the case that successful delivery of packet is not possible (i.e., either one or both of the channel conditions are "Bad").

Furthermore, when the relay nodes received the original packet, the packet will be copied and stored in the buffer of the relay nodes.

The above results confirm that using buffer in relay improves the throughput as well as the average end-to-end packet delay in the system.

On the other hand, as shown in Fig. 15, buffer-aided relaying leads to queueing in the relay buffer, which helps to utilize the channel variations efficiently.
