    摘要:

    本文研究了無(wú)線(xiàn)傳感網(wǎng)絡(luò )( Wireless Sensor Network,WSNs)的節點(diǎn)定位問(wèn)題,并針對APIT由于錨節點(diǎn)在低密度環(huán)境下的節點(diǎn)誤判和節點(diǎn)失效等問(wèn)題給出了改進(jìn),在A(yíng)PICT定位算法的基礎提出了聯(lián)合分步定位算法UNION-APICT(Union Approximate Point-In-Circumcircle Test),該算法是結合連通性的測距技術(shù),RSSI測距技術(shù)以及質(zhì)心定位和APICT等技術(shù),來(lái)聯(lián)合解決對未知節點(diǎn)定位問(wèn)題。通過(guò)仿真實(shí)驗結果表明,改進(jìn)后的UNION-APICT在A(yíng)PICT算法的基礎之上平均定位誤差減少了10%-25%,定位性能有了明顯的提升;隨著(zhù)通信半徑R和最大探測距離rmax的增加,定位誤差也在逐漸減小,該算法較APIT和APICT定位算法在錨節點(diǎn)密度、節點(diǎn)覆蓋率和定位精度上都有所提高。

    Abstract:

    The classic APIT(approximate Point-in-Triangulation test) algorithm has been utilized in node localization in wireless sensor networks for major applications, however, it is easily fall into nodes misjudgments and node failure as its accuracy can not be guaranteed in low node density scenarios. To solve this problem, this paper proposes an improved node localization algorithm UNION-APICT(union approximate Point-in-Circumcircle test) which focuses on improving the localization accuracy by combining the connected ranging method, the RSSI ranging technology, the centroid localization and APICT together, which can solve the unknown node localization problem effectively. The simulation experiment results demonstrate that the UNION-APICT can achieve the lower average location error as much as 10% to 25% than APICT scheme. And when the communication radius R and the maximum detection range Rmax increasing, the node localization error decreasing accordingly. Compared with the APIT and APICT localization algorithms, the new UNION-APICT can get performance improvement significantly both in anchor nodes density, the coverage, and localization accuracy.
