Due to the physical separation of underwater nodes, transmissions are intended to occur concurrently to maximize network capacity. Currently available approaches for improving fairness are frequently at the expense of network capacity. Methods that seek a better trade-off between fairness and network capacity are required. This paper proposes a novel approach to maximize network capacity and improve communication fairness by increasing simultaneous communications, achieving time-sharing, and spatial-reuse UWSNs. It is a distributed, multi-agent reinforcement learning approach that utilizes an observation encoder and a local utility network to coordinate collaboration across underwater nodes by adaptively tuning transmit parameters in response to local observations. In terms of network capacity, fairness, and reuse, we compared the suggested methodology to standard methods. Experiments reveal that, when compared to other ways, ours maximizes reuse and produces a significantly superior trade-off between network capacity and fairness, while still meeting lifetime and energy restrictions. The work presented in this article is anticipated to develop into valuable tools for designing and optimizing UWSNs.","PeriodicalId":191580,"journal":{"name":"Proceedings of the 15th International Conference on Underwater Networks & Systems","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134139420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case, it is necessary to build network management and device management for mobile U-IoT applications. This paper deals with underwater network management and device management concerning node mobility for underwater acoustic sensor networks (UWASNs). Moreover, in order to support a lightweight network management system for UWASN applications, this paper provides a framework and unique managed objects (MOs) design for management information based (UW-MIB) in UW-NMS.

In this paper we present a Wi-Fi based underwater acoustic network, called uw-WiFi. which is robust, highly customizable, energy efficient to tackle the real harsh underwater environment and meet the diverse application requirements. We first give a detailed design of uw-WiFi including the network architecture and protocols at different layers. Following that, we conduct a case study with 5 different kinds of network nodes.

To support the high quality of service (QoS) requirements of the involved communication tasks, one solution is to rely on multi-mode (i.e., acoustic, optical, magnetic induction (MI), and radio frequency (RF)) communication systems. Such a multi-mode communication system can take advantage of the complementary modes’ features, to obtain QoS requirements per transmission flow. However, challenges including high system cost and coordination between different modes need to be addressed. Therefore, in this paper a Universal Underwater Software Defined Radio (UniSDR) architecture is proposed that realizes joint operation of different modes, in order to deal with the latest use cases demands. Detailed description of the UniSDR architecture is presented. Novelty of the architecture provides flexibility, allowing designer to build a radio that includes any set of modes, which can operate jointly by exchanging data, control and synchronization. A numerical evaluation is conducted to assess the performance of the proposed UniSDR architecture. It clearly shows that the utilization of UniSDR allows to decrease the transmission latency and improve energy efficiency, while maintaining the reliability and robustness.","PeriodicalId":191580,"journal":{"name":"Proceedings of the 15th International Conference on Underwater Networks & Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117278319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the applications of an underwater network are related to military or public safety scenarios, which should exhibit a high robustness to attacks and failures in order to avoid disastrous consequences even with simple Denial-of-Service attacks. The defense mechanisms and countermeasures are usually tailored to specific types of attacks. Albeit this procedure allows to obtain very effective defense mechanisms, it requires the development of different countermeasures for each possible attack. Another possible solution is to use reputation systems to identify the attackers; hence, in this paper we design a trust model able to tackle a wide range of attacks. The idea of the trust model is to observe the behavior of the nodes overhearing the neighbors’ transmissions and use this information in a subjective logic framework to assign a trust metric to each of the neighbors. In addition, in order to take into account the unique characteristics of the underwater acoustic channel, which alternates periods of high packet loss to periods with low errors, we include the channel state in the trust model to avoid to erroneously mark as not trustworthy nodes that correctly forwarded the packets, but could not be overheard due to an unreliable channel.","PeriodicalId":191580,"journal":{"name":"Proceedings of the 15th International Conference on Underwater Networks & Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commonly, it is not easy to obtain auxiliary information before the network is established, such as accurate geographical position, environmental characteristics, and topological structure. The problem of asymmetry between communication uplink and downlink among nodes occurs due to the differences in transmission source level, transmission directivity, background noise, and propagation conditions of different nodes. To solve this problem, a self-organization method based on directed graph of the underwater acoustic network is proposed. In this proposed method, an adjacency matrix is established by adding the \"neighbor discovery\" phase before a round of simple flooding-based broadcasts and \"inquire-reply\" phase after that. The routing table is calculated based on the adjacency matrix using the classical shortest route algorithm to quickly complete the self-organization of the network with asymmetric communication links.","PeriodicalId":191580,"journal":{"name":"Proceedings of the 15th International Conference on Underwater Networks & Systems","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126157089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
