Abstract

Underwater optical wireless communication (UOWC) is an emerging technology for underwater wireless sensor networks (UWSNs). Compared with acoustic waves and radio frequency waves, optical waves can provide higher data rates and lower latency. However, given the limited transmission range and energy supply, as well as the existence of communication void regions in UOWC which may further deteriorate its transmission performances (e.g. packet deliver rate), effective multi-hop routing schemes are highly desirable for UOWC to expand its transmission range with satisfactory performance. In this paper, we propose a dual-hop topology-aware (DHTA) routing algorithm for UOWC. By adopting dual-hop routing strategy, the proposed algorithm reduces the packet entry possibility into void regions, and thus improves the packet deliver rate. And by selecting the next relay node considering both the available distance of transmission and the deviation of transmission direction, the proposed algorithm can effectively reduce the average energy consumption of the network. Besides, a threshold is employed by the proposed algorithm for energy balance to prevent excessive energy consumption of some nodes. The simulation results verify that the proposed DHTA routing algorithm effectively alleviates the effluence of void regions on forwarding packet and increases the packet delivery rate (PDR), with reduced average energy consumption and energy standard deviation.

水下光无线传感器网络的双跳拓扑感知路由协议

水下光无线通信(UOWC)是一种新兴的水下无线传感器网络技术。与声波和无线电波相比，光波可以提供更高的数据速率和更低的延迟。然而，考虑到UOWC有限的传输范围和能量供应，以及UOWC中存在的通信空洞区可能会进一步降低其传输性能(如分组发送速率)，有效的多跳路由方案是UOWC在满足性能的情况下扩展其传输范围的迫切需要。在本文中，我们提出了一种双跳拓扑感知(DHTA)的UOWC路由算法。该算法采用双跳路由策略，减少了报文进入空洞区域的可能性，从而提高了报文的投递率。该算法通过综合考虑可用的传输距离和传输方向的偏差来选择下一个中继节点，可以有效降低网络的平均能耗。此外，算法采用阈值进行能量平衡，防止部分节点能量消耗过大。仿真结果验证了所提出的DHTA路由算法有效地缓解了空洞区对转发数据包的影响，提高了数据包的投递率，降低了平均能耗和能量标准差。
