摘要
对自动请求重传(ARQ)技术和前向纠错(FEC)技术的能效进行了分析,提出在无线传感器网络中使用Chase合并混合自动请求重传(HARQ)方案实现自适应差错控制,以满足无线传感器网络的不同链路对差错控制方案的差异性要求。仿真结果表明,Chase合并HARQ为整体最优的差错控制方案。
Energy efficiency analyses of automatic repeat request (ARQ) and forward error correction (FEC) techniques were presented. Chase combining hybrid ARQ (HARQ) was proposed to achieve adaptive error control in wireless sensor networks. Moreover, Chase combining HARQ was compared with ARQ and FEC in terms of energy efficiency based on different communication distances and packet lengths. The simulation result shows that Chase combining HARQ is the optimal scheme on the whole.
