| 摘 要： | 随着传感器网络中节点密度的增大和跳数的增加,单信道802.15.4网络容量急剧下降,一种有效的解决方法是为网络中每个节点装配多个射频。介绍了双射频多信道802.15.4传感器网络节点的设计,详细分析了链式拓扑中单跳和多跳802.15.4网络吞吐量的理论上限,最后对单跳和多跳802.15.4网络吞吐量和时延进行了实际测量。结果表明,使用多射频多信道方案能够显著提高网络性能。

| Abstract: | In single-channel wireless sensor networks of 802.15.4,the network capacity decreases rapidly as the node density and the number of hops increase.To improve this problem,a promising way is equipping each node with multiple radios.Firstly,node design of dual-radio multi-channel 802.15.4 wireless sensor network is introduced in this paper.Then a detailed analysis of the theoretical upper bounds of single-hop and multi-hop throughput for chain topol-ogy is presented.Finally the experiments ale carried out to measure the practical throughput and latency of single-hop and multi-hop 802.15.4 network.Experimental results validate the distinguished network performance improvement achieved by using multi-radio multi-channel approach. |
