摘要: 研究不同速率BCH码情况下提高无线传感器网络吞吐量的方法,给出单一编码方案对网络性能的影响及网络主节点(NM)对网络寿命和吞吐量的影响。仿真结果表明,在传感器和网络主节点(NM)之间、NM和sink之间采用不同速率/编码时,网络吞吐量随BCH编码率的增加而增加,多编码方案能更高效地提高网络吞吐量。

关键词: 无线传感器网络, BCH编码, 多编码方案, 单编码方案, 网络寿命, 吞吐量

Abstract: This paper focuses on how to use a different encoding scheme to improve network throughput. That is, different rates/codes are studied between sensor nodes and the Network Master(NM) and between the NM and the sink. Research results show that throughput increases with the increase of the BCH coding rate. Simulation results also show that the high rate BCH code provides a higher throughput than the low rate BCH code using the single coding scheme. The multi-coding scheme is more efficient and has a very good effect on network throughput over lifetime.

Key words: Wireless Sensor Network(WSN), BCH coding, multi-coding scheme, single coding scheme, network lifetime, throughput
