摘要
鉴于GPS定位在水声通信网中的局限性,提出了一种利用TOA方法测得的距离信息确定节点位置的定位算法,并针对水声信道中通信冲突严重的问题,重点研究了在水声通信网的自组织形成过程中,实现该定位算法的一种无冲突数据传播方案,最后利用OPNET仿真验证了2种算法配合完成水声通信网纯距离节点定位的可行性。
Because of the restrictions of using GPS in underwater acoustic networks, a node locating arithmetic based on the distance information obtained from the method TOA is given in this article. Considering the serious communication conflicts in underwater acoustic environments, a data transmitting arithmetic which achieves no-collision information exchanges among nodes to realize the locating arithmetic is expatiated as well. Finally, the feasibility of fulfilling the distance - only node locating in the underwater acoustic network using the two arithmetic above is validated through OPNET simulation.
