LIU Yuan, YAN Bin, LI Zhi, et al. Design and implementation of voice communication mechanism based on WSNs[J]. 2016, 35(2): 97-99. DOI: 10.13873/J.1000-9787(2016)02-0097-03.
Aiming at shortage of wireless sensor networks( WSNs) for voice transmission
design and implement a kind of wireless voice communication mechanism based on WSNs. Adopt CC2530 as microprocessor chip which integrates 8051 CPU and RF transceiver
uses CMX649 as speech codec chip
using coprocessor to assist CC2530 to process speech information
and realize voice transmission over procotol IEEE 802. 15. 4. Introduce design of hardware and software of the system in detail
and test distance and quality of voice communication. Experimental result show that this mechanism has far transmission distance
