| 摘 要： | 当水声网络的所有节点完成在目标区域的部署后,每个节点除了自己的节点ID已知外,对新网络的信息一无所知,而这些信息是网络顺利运行的必要前提。因此,一个能够完成网络中所有节点和链路发现的网络拓扑发现协议是非常必要和重要的。水声拓扑发现协议完成的效率,往往依赖于信道接入策略的选择,但它不能完全使用已有的水声多路访问控制(multiple access control, MAC)协议,因为在网络建立的初始阶段拓扑未知,已有传统水声MAC协议不能完成拓扑发现,所以需要根据这一阶段的特殊状态来设计拓扑发现协议。基于此问题,提出了一种高效的冲突避免的水声网络拓扑发现(简称为CFVE)协议,该协议利用网络中节点ID的唯一性,在其特定时隙接入信道,节点无冲突地发现控制分组的交换,最终实现网络中所有链路和节点的发现。仿真结果表明, CFVE协议可以以较低的发现时延和能耗完成全网拓扑的发现,是一种适合于多跳水声网络的拓扑发现协议。

| Abstract: | When all nodes of an underwater acoustic network (UAN) are deployed in the target region, each node knows nothing about the new network except its own node ID, so a network topology discovery protocol that can complete nodes and links discovery for all nodes is necessary and significant. The efficiency of the underwater acoustic topology discovery protocol often depends on the choice of the channel access strategy, but it cannot completely use the existing underwater acoustic multiple access control (MAC) protocols. Because it is in the initial stage of the network establishment, the access strategy needs to be designed according to the special state of this stage. An efficient collision-free topology discovery protocol (named CFVE) for UAN is proposed. This protocol makes use of the uniqueness of the node ID in the network, and the nodes access the channel in their specific time slot, and then exchange the discovery control packets without conflicts, and finally realize the discovery of all links and nodes in the network. Simulation results show that the CFVE effectively reduces energy consumption and decreases discovery delay and accurately obtains the whole network topology during the network topology discovery. The proposed CFVE protocol is a suitable network topology discovery mechanism for UANs. |
