| 摘 要： | 节点位置信息对声纳浮标网络的建立具有十分重要的意义,利用它可以完成节点身份划分、路由建立等工作.鉴于传统GPS广播方式的低效性,提出了一种GPS共享协议,并利用网络仿真软件OPNET仿真证明:该协议能够以无冲突方式快速实现网络节点GPS信息的共享和拓扑结构的自辨识.同时,针对GPS所固有的定位偏差问题,提出了一种网络节点GPS求精算法,OPNET仿真证明:该算法可提高对网络整体拓扑结构的把握精度.

| Abstract: | Position information of nodes which is very important to the establishment of sonobuoy networks can be used to fulfill a lot of work,such as marking nodes′ identities and building the routing table.In view of the low efficiency of traditional GPS transmission mode,a GPS shared protocol was presented to realize the quick transmission of GPS at nodes and the self-recognition of the network topology in a non-conflicting way.In order to overcome errors in the localization of GPS systems,an algorithm to improve the recognition precision was brought forward.The OPNET simulation proves that the algorithm can improve the precision of the integral network topology. |
