摘　　要：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 as well as coexistence the requirement of between its own standard and the Internet,6LOWPAN emerges as the times demand.The performance parameters of 6LOWPAN include energy consumption,transfer delay,received signal strength indicator and packet-loss rate.The specific analysis shows that IEEE802.15.4channel selection affects transfer duration.The number of nodes,the attendance or absence of CBR could change the value of communications volume and consumed energy.Experiments indicates that the channel selection of 26 would be the best.
