The Cister/Rssi Dataset

We use a sensor network composed of TelosB motes deployed in the library building to collect RF energy level samples (RSSI) on all 802.15.4 channels in the 2.4 GHz ISM Band. The building has several collocated Wi-Fi networks in normal operation. These networks produce interference for the 802.15.4 radios. Sensor nodes record RSSI values every 20 us, simultaneously on all channels, for 130 ms and then write the result to the respective files. This process is repeated every 8 seconds for around 4h. ; [e-mail]本研究采用部署于图书馆楼宇的、由TelosB无线传感节点（TelosB motes）组成的传感器网络，采集2.4 GHz工业科学医疗（ISM）频段内所有802.15.4信道的射频能量电平采样值（接收信号强度指示，RSSI）。该楼宇内部署有多台处于正常运行状态的共址Wi-Fi网络，此类网络会对802.15.4无线收发器造成干扰。传感节点每20微秒便会同时在所有信道上记录一次RSSI值，持续采集时长为130毫秒，随后将采集结果写入对应文件。该采集流程每8秒重复一次，总采集时长约为4小时。; [e-mail]
