Moreover, we observe that the Video traffic is more impacted by the gain in throughput, which is because Video flows usually require additional RBs compared to CBR or VoIP flows given the lower data rate and packet size.
Significance of this overhead is, however, decreasing with the expected number of active transmission sub-frames L (i.e., with bigger data packets and/or lower data rates).
Similar effect is observed about FHDR; however, since it does not determine the type of time slot based on the demands and does not use the subchannel and power resources efficiently, it leads to higher queue sizes in the BS and consequently, lower data admissions in high packet arrival rates.
This can be noticed from Fig. 4 that the performance of LBMODV is much better with lower data loads of 100 packets in this case.
However, as the network becomes saturated, the offered load increases with an increase in N, which leads to more packet collisions, and thus higher service time for each data packet and lower throughput.
This indicates that in case of bigger packet sizes and/or lower data rates available for the multi-hop connection, problems with satisfying the packet delivery time might occur on wide scale even for users with satisfied GBR requirement.
This limitation wastes resources in terms of higher number of collisions of the packets, delay with lower data reliability and BMSs consume more energy RF-MAC [52] Low High Nodes perform contention to access channels in CAP period.
When the data packet transmission rate was lower, this method was effective.
In addition, packet partitioning schemes for VpD have lower data rates compared to D-VpD.
In contrast, UtdMAC has higher probability of packet success due to backup relay path, but provides lower data rate depending upon source-destination separation.
