Abstract

Multi-hop communication in Underwater Acoustic Sensor Network (UASN) brings new challenges in reliable data transmission. Recent work shows that data collection from underwater sensor nodes using Autonomous Underwater Vehicle (AUV) minimizes multi-hop data transmission, improving energy efficiency in UASN. However, due to continuous movements, AUV has limited communication time to collect data from sensor nodes in UASN. We therefore propose a novel underwater routing protocol, namely AEERP (AUV aided Energy Efficient Routing Protocol). In AEERP, an AUV collects data from gateway nodes. Among all the nodes, selected nodes play the role of gateway node for communication with AUV. Gateway nodes are selected based on RSSI values of the hello packet received from AUV. In addition, after consuming energy up to a certain threshold by a gateway node, another high energy node is selected as a gateway node. This adaptive selection of gateway node balances energy consumption increasing network lifetime. Mathematical analysis and NS-2 simulation show that AEERP performs better than Travel Salesperson Problem (TSP) in terms of energy cost and data delivery ratio.

AEERP:水下航行器辅助的水声传感器网络节能路由协议

水声传感器网络(UASN)中的多跳通信对数据的可靠传输提出了新的挑战。最近的研究表明，使用自主水下航行器(AUV)从水下传感器节点收集数据可以最大限度地减少多跳数据传输，提高usasn的能源效率。然而，由于AUV的持续运动，它在usasn中收集传感器节点数据的通信时间有限。因此，我们提出了一种新的水下路由协议，即AEERP (AUV辅助节能路由协议)。在AEERP中，AUV从网关节点收集数据。在所有节点中，选定的节点充当与AUV通信的网关节点。根据AUV接收到的hello报文的RSSI值选择网关节点。另外，当一个网关节点消耗能量达到一定阈值后，选择另一个能量较高的节点作为网关节点。这种网关节点的自适应选择平衡了能量消耗，增加了网络寿命。数学分析和NS-2仿真表明，AEERP在能量成本和数据交付率方面优于旅行销售员问题(TSP)。
