Example text

Fig. 4 shows that for both increasing and fixed packet size, synchronous broadcast-based aggregation is able to achieve lower maximum data age than the unicast-based protocol at 40% physical layer loss rate. The increase of the physical layer loss rate has a similar impact on the asynchronous protocols. As the network density increases, the broadcast-based protocols are expected to achieve higher reliability as a broadcast is likely to be received by more nodes. However, for broadcast-based aggregation with increasing packet size, J.

For fixed packet size, however, performance with the broadcast-based protocol improves but degrades with unicast-based aggregation. Similar results are seen with the asynchronous protocols. Fig. 6 shows the average number of bytes that are transmitted per round with the synchronous aggregation protocols, for a 20% physical layer packet loss rate. While broadcast-based aggregation sends fewer packets per round than unicast-based aggregation, as shown in Fig. 7, a larger volume of data is produced by broadcast-based aggregation in the case of increasing packet size.
