| 摘 要： | 从数据源到数据接收者的数据分发是无线传感器网络的重要功能．本文提出了分频数据分发协议，该协议通过多棵分发树对数据接收者进行数据分发，从而最大限度地重用数据传输路径．实验表明，在数据接收者较多的情况下，分频数据分发协议比现有最好的数据分发协议SEAD的加权路径长度要短15％左右，从而有效节省了分发数据的能量消耗，延长了系统生命期． |

| Abstract: | Data dissemination from data source to data sinks is one important function of wireless sensor network. This paper presents a frequency-divided data dissemination scheme. This scheme tries to reuse data transmission path excessively. Data source disseminates data to data sinks through multi dissemination trees. Simulation shows that when the number of data sinks is large, frequency-divided data dissemination outperformed previous best data dissemination scheme SEAD about 15% in weighted path length. Then energy consumption of data dissemination is reduced and system lifetime is prolonged. |
