Upon successful reception, the destination station broadcasts a STATUS packet acting as acknowledgment.
In (5) slot refers to a transmission slot and successful transmission includes transmission by source, forwarding by relay and reception by destination.
The contradiction at the heart of the matter is that, despite the recognized need for migrant nurses, migrants are generally afforded a much cooler reception by destination countries [ 8].
Therefore, broadcast reliability (in terms of successful reception at destinations) also quickly decreases with an increase in contending population size.
It is observed that when the formulated problem is feasible, all these four schemes can provide robust data reception for destinations.
Any cached packets whose reception by the destination is confirmed by the destination are purged from the cache, releasing memory space to cache ensuing packets.
In NCCARQ-MAC, upon erroneous packet reception by the destination, the relay will encode the retransmission request from the destination with a newly arrived packet from the source and send them out in one broadcasting event.
Similarly, (24) to (27) shows the probability of transmission (by source) and reception (by relay, destination and overhearing nodes) of packets in error.
The issue of asynchronous reception at the destination node can be addressed by the proposed DT-ACMO algorithms, while the BER performance is improved by the optimization algorithms.
This is much smaller than the packet duration (which leads to insignificant fade and can be easily handled by the existing equalizer technology at physical layer [11]) and, hence, leads to error-free reception at the destination node.
Packet-level redundancy increases the average percentage of successful packet reception at the destination when compared with unreliable transmissions, while it does not significantly compromise the transmission delay [5, 6].
