【摘要】：提出一種利用線性調(diào)頻擴頻技術(shù)進行通信并實現(xiàn)測距的方法,該測距方法能夠適用于復(fù)雜室內(nèi)通信環(huán)境的無線傳感器網(wǎng)絡(luò)節(jié)點間的測距。在三邊測距定位的基礎(chǔ)上,提出了四邊測距定位算法,突破了三邊測距定位的局限性。為了進一步提高精度,采用了求質(zhì)心和加權(quán)質(zhì)心的方法。實驗結(jié)果表明,加權(quán)質(zhì)心算法具有較高的精度,整個定位過程中,節(jié)點間無需額外的通信開銷,具有廣泛的實用性。
[Abstract]:This paper presents a method of communication and ranging using LFM spread spectrum technology, which can be applied to ranging between wireless sensor network nodes in complex indoor communication environment. On the basis of trilateral location, a four-sided location algorithm is proposed, which breaks through the limitation of trilateral location. In order to further improve the accuracy, the method of centroid and weighted centroid is adopted. The experimental results show that the weighted centroid algorithm has a high accuracy, and it has a wide range of practicability in the whole localization process without additional communication overhead.
