… delay is derived in terms of the number of channels K, number of users N and other system
parameters. Our results allow us to study the scalability of the OFDMA-Aloha … packet delay in …

… In this paper, the delay analysis is extended from constant noiseless channels to fading
channels, where the information encoding rate and mean received SNR of each packet are key …

… of RA delay of multichannel S-ALOHA, as well as its cumulative density function and average
value. Under stable RA attempts assumption, simplified form of the above analysis is given, …

… Delay Analysis of Aloha Due to the contention in the shared channel, the grant-free random
access often suffers from low efficiency and poor delay performance as successful channel …

… delay analysis, and has a huge impact on later studies of throughput and access delay …
the throughput and mean access delay, the mean queueing delay of data packets is infinite …

… This paper aims at proposing an e2e delay analysis method for an integrated IoTDs-EC
system, by resorting to the combined application of the martingale envelopes theory and the SNC…

… delay analysis, and has a huge impact on later studies of throughput and access delay …
the throughput and mean access delay, the mean queueing delay of data packets is infinite …

… Next, we analyze OFDMA-Aloha which is the simplest protocol that utilize the frequency…
in these situations OFDMA-Aloha enjoys smaller packet delays than the single channel Aloha. …

… In this system, besides making the identical assumptions as those in OFDMA-Aloha, we
ignore the impact of hidden terminals. In the OFDMA-CSMA, T′ is random and depends on the …

… wireless communication using ALOHA and OFDMA-ALOHA which is model 1… OFDMA-ALOHA.
The performance of developed model has been evaluated in terms of mean access delay …
