Abstract

Underwater wireless sensor network (UWSN) has emerged as one of the most popular network technologies owing to its applicability to offshore searches, and underwater monitoring and exploration applications. It has been shown to be useful in the fields of investigations and surveillance, and in assisting with and offering solutions to water-based calamities. Reliability in the underwater environment has caused researchers to direct attention towards improving the overall efficiency and energy utilisation of the network. In the present paper, reliable node quester (RNQ) algorithm has been formulated to calculate the node reliability for numerous parameters such as success rate, transmission time, and the affordability, congestion and stability of the nodes. The present paper highlights the data-forwarding mechanism of the nodes to enhance overall network reliability by (i) reducing the packet drop rate; (ii) increasing the packet delivery ratio; and (iii) minimising the energy consumption. Simulation results further support the proposed strategy by ensuring the network lifespan and detection accuracy.

基于参数约束的水声传感器网络簇头节点可靠性研究

水下无线传感器网络(UWSN)由于其适用于海上搜索、水下监测和勘探等应用，已成为最受欢迎的网络技术之一。它已被证明在调查和监测领域以及在协助和提供解决水基灾害的办法方面是有用的。水下环境下的可靠性已经引起了研究人员对提高网络整体效率和能源利用率的关注。本文提出了可靠节点请求(reliable node quester, RNQ)算法，用于计算节点在成功率、传输时间以及节点的可承受性、拥塞性和稳定性等众多参数下的可靠性。本文重点介绍了节点的数据转发机制，通过(1)降低丢包率来提高整体网络的可靠性;(ii)提高分组传送率;(三)尽量减少能源消耗。仿真结果进一步支持了该策略，保证了网络寿命和检测精度。
