To enhance reliability in sparse node regions and reduce network energy consumption, this paper proposes a dependable and energy-efficient routing protocol termed WLQRP for weighting link-quality-based routing protocol. WLQRP leverages link quality information between nodes for data forwarding. When computing the link quality between nodes, it considers not only the historical transmission success ratio between nodes and their immediate relay but also incorporates the link quality between the relay and the relay\u2019s next-hop nodes. This approach effectively reduces the likelihood of encountering void regions. Moreover, the protocol judiciously selects the next-hop node to improve transmission success rates, thereby minimizing data packet retransmissions and reducing energy consumption. We conduct MATLAB simulations to evaluate the WLQRP protocol, comparing it against the VBF (vector-based forwarding) and the HH-VBF (hop-by-hop vector-based forwarding) underwater routing protocol. Experimental results demonstrate that WLQRP enhances network performance in terms of data transmission rate, energy consumption, and end-to-end delay. These findings validate the efficacy of the proposed protocol.<\/jats:p>","DOI":"10.3390\/rs15245651","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T11:32:29Z","timestamp":1701862349000},"page":"5651","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["WLQRP: A Weighting Link-Quality-Based Routing Protocol for Underwater Sensor Networks"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1492-2340","authenticated-orcid":false,"given":"Jianmin","family":"Yang","sequence":"first","affiliation":[{"name":"School of Ocean Engineering and Technology, Sun Yat-sen University, Zhuhai 519000, China"},{"name":"Key Laboratory of Comprehensive Observation of Polar Environment (Sun Yat-sen University), Ministry of Education, Zhuhai 519082, China"},{"name":"Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai 519000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahui","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Ocean Engineering and Technology, Sun Yat-sen University, Zhuhai 519000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haitao","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Tourism and Landscape Architecture, Guilin University of Technology, Guilin 541006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yexin","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Ocean Engineering and Technology, Sun Yat-sen University, Zhuhai 519000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuoqian","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Ocean Engineering and Technology, Sun Yat-sen University, Zhuhai 519000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhihong","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Ocean Engineering and Technology, Sun Yat-sen University, Zhuhai 519000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11176","DOI":"10.1109\/ACCESS.2017.2713640","article-title":"Review on Clustering, Coverage, and Connectivity in Underwater Wireless Sensor Networks: A Communication Techniques Perspective","volume":"5","author":"Sandeep","year":"2017","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"72","DOI":"10.1109\/48.820738","article-title":"Underwater Acoustic Networks","volume":"25","author":"Sozer","year":"2000","journal-title":"IEEE J.
