许多自组织网络协议和应用程序都假设了解节点的地理位置。每个网络节点的绝对位置是大多数传感器网络的假设事实，然后可以在地理地图上呈现感测到的信息。在 GPS 无法访问或由于功率、外形尺寸或视线条件而无法实际使用的情况下，在自组网络的每个节点中不借助 GPS 来查找位置非常重要。位置还可以在充分各向同性的大型网络中实现路由，而无需使用大型路由表。我们提出 APS——一种本地化、分布式、逐跳定位算法，它作为距离矢量路由和 GPS 定位的扩展，以便为网络中只有有限部分节点具有自定位能力的所有节点提供近似位置。
Many ad hoc network protocols and applications assume the knowledge of geographic location of nodes. The absolute position of each networked node is an assumed fact by most sensor networks which can then present the sensed information on a geographical map. Finding position without the aid of GPS in each node of an ad hoc network is important in cases where GPS is either not accessible, or not practical to use due to power, form factor or line of sight conditions. Position would also enable routing in sufficiently isotropic large networks, without the use of large routing tables. We are proposing APS-a localized, distributed, hop by hop positioning algorithm, that works as an extension of both distance vector routing and GPS positioning in order to provide approximate position for all nodes in a network where only a limited fraction of nodes have self positioning capability.
