基于Aloha的连续干扰消除(SIC)中的最佳报头定位
Optimum Header Positioning in Successive Interference Cancellation (SIC) based Aloha
摘要:
随机接入MAC协议是简单而有效的流量的性质是不可预测的和零星的。在下面的论文中,研究了新的增强竞争解决ALOHA(ECRA),其中一些新的方面的协议进行了研究。文中给出了SIC后符号干扰概率的数学推导和数值计算。被发现是在开始和结束的数据包的最佳头部定位的结果,利用ECRA吞吐量和数据包出错率(PER)的评估下,不完善的知识包的位置。ECRA w.r.t.竞争解决ALOHA(CRA)在这个假设下。
英文摘要:
Random Access MAC protocols are simple and effective when the nature of the traffic is unpredictable and sporadic. In the following paper, investigations on the new Enhanced Contention Resolution ALOHA (ECRA) are presented, where some new aspects of the protocol are investigated. Mathematical derivation and numerical evaluation of the symbol interference probability after SIC are here provided. Results of the optimum header positioning which is found to be in the beginning and in the end of the packets, are exploited for the evaluation of ECRA throughput and Packet Error Rate (PER) under imperfect knowledge of packets positions. Remarkable gains in the maximum throughput are observed for ECRA w.r.t. Contention Resolution ALOHA (CRA) under this assumption.
