Underwater Acoustic Sensor Networks (UASN) have two important limitations: a very aggressive (marine) environment, and the use of acoustic signals. This means that the techniques for terrestrial wireless sensor networks (WSN) are not applicable. This paper proposes a routing protocol called "Self-Organizing and Scalable Routing Protocol" (SOSRP) which is decentralized and based on tables residing in each node. A combination of the hop value to the collector node and the distance is used as a criterion to create routes leading to the sink node. The expected functions of the protocol include self-organization of the routes, tolerance to failures and detection of isolated nodes. Through the implementation of SOSRP in Matlab and a model of propagation and energy being appropriate for marine environment, performance results are obtained in different scenarios (varying both nodes and transmission range) that include parameters such as end-to-end packet delay, consumption of energy or length of the created routes (with and without failure). The results obtained show a stable, reliable and suitable operation for the deployment and operation of nodes in UASN networks.
水下声学传感器网络(UASN)有两个重要局限:一是极端恶劣的(海洋)环境,二是使用声学信号。这意味着陆地无线传感器网络(WSN)的技术并不适用。本文提出了一种名为“自组织可扩展路由协议”(SOSRP)的路由协议,该协议是分散式的,基于每个节点中的表格。到收集器节点的跳数与距离的组合被用作创建通向汇聚节点路由的标准。该协议的预期功能包括路由的自组织、对故障的容忍以及孤立节点的检测。通过在Matlab中实现SOSRP以及适合海洋环境的传播和能量模型,在不同场景(节点数量和传输范围均不同)下获得了性能结果,这些场景包括诸如端到端分组延迟、能量消耗或创建路由的长度(有故障和无故障)等参数。所获得的结果表明,该协议对于UASN网络中节点的部署和运行具有稳定、可靠且适用的运行效果。
