随着无线传感网技术的快速发展以及它自身的标准要与互联网共存的需要,6LOWPAN应运而生。6LOWPAN性能参数包括能量消耗,传输时延,接收信号强度指示和丢包率等。通过实施具体的实验分析得出IEEE802.15.4信道选择影响数据传输时间。节点个数和有无恒定比特率(CBR,Concurrent Constant Bit Rate)则会改变网络通信量,能量消耗等性能指标值。深入探讨了各种参数对6LOWPAN性能的影响,主要研究了IEEE802.15.4信道选择以及恒定比特率的作用。通过硬件和软件实验也证明了信道选择26时网络性能最好。
With the rapid development of wireless sensor network technology and its own standards to coexist with the needs of the Internet, 6LOWPAN came into being. 6LOWPAN performance parameters include energy consumption, transmission delay, received signal strength indication and packet loss rate. Through the implementation of specific experimental analysis obtained IEEE802.15.4 channel selection affect data transmission time. The number of nodes and the Constant Concurrent Bit Rate (CBR) will change the network traffic, energy consumption and other performance indicators. The effects of various parameters on the performance of 6LOWPAN are discussed in depth. The effects of channel selection and constant bit rate of IEEE802.15.4 are mainly studied. The hardware and software experiments also proved that the network performance is the best when channel selection is made.
