我们考虑一个网络的缓冲区辅助无线设备发送的最后期限约束的数据包时隙ALOHA随机接入信道。虽然基于重传的通信增强了可靠性，但队列中的数据包的传输被延迟，因此，它们可能在成功传输之前被丢弃。在这项工作中，我们研究了最后期限约束的突发流量与重传提供了一个基于马尔可夫链的分析的性能。其目的是揭示作为到达率的函数的数据包的最后期限和重传次数之间的权衡，并铺平道路，找到最佳的重传次数，给定的数据包的最后期限和数据包的到达率。此外，性能评估进行不同的发送概率和不同的重传次数的用户。结果揭示了这些参数对丢弃概率和平均吞吐量的影响，这些参数显示了在哪些值下可以获得更好的性能。
We consider a network of buffer-aided wireless devices having to transmit deadline-constrained data packets on a slotted-ALOHA random-access channel. While retransmission-based communication enhances reliability, the transmission of packets in the queue is delayed and as a result, they might get dropped before they are transmitted successfully. In this work, we study the performance of deadline-constrained bursty traffic with retransmissions providing a Markov chain-based analysis. The aim is to reveal the trade-off between the packet deadline and the number of retransmissions as a function of the arrival rate, and pave the way towards finding the optimal number of retransmissions, given the packet deadline and packet arrival rate. Furthermore, performance evaluation is conducted for a user with varying transmit probability and different number of retransmissions. The results reveal the effect of these parameters on the drop probability and average throughput showing the values under which, improved performance can be obtained.
