Abstract

A new hybrid automatic repeat request (HARQ) scheme for multicast service for wireless sensor networks is proposed in this study. In the proposed algorithm, the HARQ operation is combined with an autonomous retransmission method that ensure a data packet is transmitted irrespective of whether or not the packet is successfully decoded at the receivers. The optimal number of autonomous retransmissions is determined to ensure maximum spectral efficiency, and a practical method that adjusts the number of autonomous retransmissions for realistic conditions is developed. Simulation results show that the proposed method achieves higher spectral efficiency than existing HARQ techniques.

摘要

本研究提出了一种用于无线传感器网络多播服务的新型混合自动重传请求（HARQ）方案。在所提出的算法中，HARQ操作与一种自主重传方法相结合，该方法可确保无论数据包在接收器处是否成功解码，都能进行传输。确定自主重传的最佳次数以确保最大频谱效率，并开发了一种针对实际情况调整自主重传次数的实用方法。仿真结果表明，所提出的方法比现有的HARQ技术具有更高的频谱效率。
