摘要

无线传感器网络（W SNs）能够实时监测和采集网络分布区域内的各种检测对象信息

有着广泛的应用前景。在W SNs中

节点定位技术是许多应用的支撑技术

定位的准确性直接关系到传感器节点采集数据的有效性。目前

已提出多种定位算法

Euc lidean算法由于通信开销小

具有一定的优越性

但在某些应用中存在定位精度较低的问题。针对这一问题

提出了一种新的改进Euc lidean的算法。用距离矢量路由技术替代直接测量节点间的距离

并运用迭代循环思想抑制定位误差的累计。计算机仿真结果证明:该改进算法能够明显地提高定位精度。

Abstract

Wireless sensor networks（WSNs）

which is utilized in a broad foregroud

is able to instantly monitor and collect various information of different objects in the network distributed area.In WSNs

sensor location plays a critical role in many application.Currently

many positioning algorithms are proposed.Euclidean has an advantage because of lower communication overhead

but high inaccuracy is compared to others.A new location algorithm is proposed to improve the inaccuracy of Euclidean.Result of the simulation shows the modified algorithm is better than the original in accuracy.
