摘要
无线传感器网络中音频数据的采集具有采样频率快、数据量大的特点,对无线传感器网络数据的存储、压缩与传输提出了挑战。结合音频数据采集的特点,针对其应用环境,提出了一种具有存储、压缩与可靠传输功能的音频数据采集协议,并在MicaZ节点硬件平台上实现了该协议的原型系统。实验表明,该原型系统可以保证音频数据的可靠传输,并能够有效减少节点的发包量。
Audio data collection in Wireless Sensor Network （WSN） has the characteristics of fast sample rate and large amount of data, thus posing new challenges to data storage, compression and transmission in WSNI Based on the above-said characteristics, an audio data collection protocol with storage, compression and reliable transmission was proposed. A prototype system based on the protocol was implemented on MicaZ nodes. Experimental results show that the prototype system can provide reliable transmission and reduce the number of packets.
