通信工程文献翻译——摘要：在无线传感器网络领域，定位系统是引起众多科研人员关注的重要项目。定位的过程就是分配或计算传感器网络中传感器节点的位置。传感器节点是随意部署的,他们自身定位、传感器节点随机部署是非常重要的。因此在这篇文章中,我们确定自身定位的解决方案是确定传感器节点位置。我们设计了一种方法，在能量接收过程中首先发现一个传感器节点的位置随之也就找到了未知传感器节点的位置。

1引言

在无线通信领域，无线传感器网络是快速成长的一个方面。它由众多传感器节点构成并可以随机部署。因此,知道自己的位置是非常重要的,在大规模传感器网络中过早的知到他们的位置是不可能的。因此自身定位的概念,获得也将成为许多研究人员的研究重点。定位这一术语指的是使用进程定义找到位置传感器在传感器网络中的节点。在大规模传感器网络中本地化是不可行的,所以自身定位非常重要。

定位的问题得到了众多的目光在研究传感器节点上，它需要知道自己的位置,传感器网络为了达到传递信息和沟通其他周边传感器节点这一目的,全球定位系统(GPS)是解决方法之一，但它不适用于大型传感器网络,因为他们相比普通传感器网络节点很贵。全球定位系统(GPS)不适用于室内的目标定位。因此利用全球定位系统（GPS）是不可行的大规模传感器网络。有许多算法都提出了本地化选择。只有那些算法能够有执行能力,自我管理,可以做到处理节点失败和范围访问错误, 当谈到无线传感器网络节点作为传感器非常有限的能量，很好地利用了考虑那些能量是最为重要的事实。保持把这些事情记在心里,在本文中,我们提出了解决问题的初步方法基于发现位置使用范围的传感器......

Abstract- Localization is the subject matter that has allured the attention of many researchers in the field of wireless sensor network. It is the process of assigning or computing the location

of the sensor nodes in a sensor network. Since the sensor nodes are randomly deployed, it is very important that they localize themselves, as the manual deployment of sensor node is not feasible. Thus in this paper, we find out the solution for localizing the sensor nodes. We have developed a novel model that first finds the distance of the sensor nodes then it finds the location of

the unknown sensor nodes in power efficient manner.

Keywords- sensor nodes, localization, scaling, multi-path fading, AoA, TDoA, MDS

I. INTRODUCTION

Wireless sensor network is one of the growing issues in the field of wireless communication. It consists of many sensor nodes that are deployed randomly. Thus, it is very important to know their location in the network, as premature knowledge of their location is not possible in large sensor network. Thus the concept oflocalization came into existence and has gained the interest of many researchers. Localization is the term used to define the process of finding the location of the sensor nodes within the sensor network. As manual localization is not feasible for large sensor network, self localization is very crucial.

The problem of localization has gained lots of attention as sensor nodes need to know their location in the sensor network in order to relay the information and communicate with the other neighboring sensor nodes. Global Positioning System (GPS) is one of the solutions for this purpose but it is not applicable for large scale sensor network as they are expensive as compared to common sensor nodes [3]. Also the GPS are not applicable for indoor purpose. Thus using GPS is not feasible for large scale sensor network. Many algorithms have been proposed for localization. But only those algorithms can......
