摘要
无线传感器网络监测数据的汇报机制是目前的研究热点。将目前无线传感器的应用分为非事件类、事件类以及混合类三大类,在设计了监测数据表现形式的基础上,着重对事件判别标准、消息的优先级、数据融合方法以及消息的汇报机制进行了分析和论述。汇报机制采用改进的队列作为缓存空间,以保证级别高的消息能够得到及时有效地的传输。实验结果表明:该机制具有冲突概率低、汇报时延小和能量消耗较少的特点。
Wireless sensor networks（WSNs） monitoring data reporting mechanism is current research hotspot. At present, the application of the WSNs are divided into no-event-class,event-class and compound-class, on the basis of design of the message format of monitoring data, event happening criterions, message priority, data fusion method and message reporting mechanism are analyzed and discussed. Reporting mechanism use modified queue and array as caching to ensure the message of higher level can be reported effectively and timely. Experimental results show that this mechanism have characteristics of low conflict,low energy consumption and less reporting delay.
