摘要:

在无线传感器网络中对传输距离与传输能量及传输速率的关系进行了研究。传统的工作对该关系的认识并不准确,而这是考虑网络各性能指标的基础。首先介绍了实验所用到的无线传感器网络节点,实验的环境及实验的设计;然后通过实验测量得到在不同传输距离上的报文丢失率,并对其进行拟合得到传输距离与报文丢失率的关系;最后在该关系的基础上考虑了报文的重传,进一步研究了传输距离对传输能量及传输速率的影响。主要贡献是在Imote2型节点平台上定量地给出了单跳节点间传输距离对无线传感器网络性能影响的评估。

Abstract:

The research was on the influence of transmission distance respectively on energy consumption and transmission rate in wireless sensor network.The views of traditional work on this impact was not so precise,which was essential to the performance of WSN.The sensor node used,experimental environment and design have been introduced;Then the packet loss ratio for different transmission distance have been examined experimentally,and their functional relation by fitting the experimental data have been acquired; finally,considering packet retransmission based on that conclusion at the same time,focused on the variance of energy cost and transmission rate with distance.The main contribution is to acquire the quantitative effect evaluation of one-hop transmission distance and performance in WSN.

Key words: wireless sensor network, Imote2, transmission distance, energy consumption, transmission rate
