In addition, media access control (MAC) protocols have a significant impact on the performance of UASNs due to their limited bandwidth, time variation, and long-propagation delayed underwater acoustic channel characteristics. This paper proposes a time-based adaptive collision-avoidance real-time (ACART) MAC protocol that combines concurrent transmission, adaptive scheduling transmission, and variable time slots to improve network throughput and channel utilization. The strategy of concurrent transmission improves channel utilization by reducing the number of handshakes. Scheduling transmission avoids packet collisions. The approach of using variable time slots increases the flexibility of the network. The simulation results show that the network throughput outperforms traditional protocols in large-scale, high-traffic load networks.","PeriodicalId":429405,"journal":{"name":"Proceedings of the 13th International Conference on Underwater Networks & Systems","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131995859","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}

At present, the commonly used network simulation platforms are NS2 and NS3, or are extended from them. These simualation platforms require users to have rich experience in C++ programming because they integrate many complicated APIs, and the configuration process is cumbersome. Without further optimizing these existing emulation platforms from the software architecture, it is often impossible for the protocol researchers to completely focus on the logic implementation of the protocol without paying attention to the compilation and loading operation of the simulation software itself. In this paper, an UAN protocol emulation platform based on microservice architecture (MSA) is proposed. The microservices are independently developed and deployed to overcome the shortcomings of the traditional monolithic architecture for the development of software system. Using MSA, the protocols and functional modules are fully componentized, which is convenient for users to customize the UAN protocol stack, network behavior, and underlying physical devices. The proposed emulation platform can be deployed as a cloud-based server and provides users with services, such as simulation on demand, emulation in real time, monitoring and statistical analyzing, and other customizable extension functions. This operation mode is called emulation as a service (EaaS). A preliminary test has verified the feasibility of the whole framework and demonstrated that our implementation fulfills the main functions of this emulation platform.","PeriodicalId":429405,"journal":{"name":"Proceedings of the 13th International Conference on Underwater Networks & Systems","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115602810","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}

Differential cyclic shift keying (DCSK) spread spectrum UWA communication using time reversal mirror (TRM) is proposed in this paper. Differential coding and decoding inhibit the influence of fast-carrier phase fluctuation effectively, and time-reversal mirror technology controls multipath propagation. A tracking/updating adaptive channel estimation algorithm used in this system estimates the real-time time-varying acoustic channel and save the effective estimation channel as the time-reversal mirror processing channel to ensure the reliability of processing. We verify that the system can achieve low bit error rate communication under the condition of fast-carrier phase fluctuation and channel multipath propagation by carrying out an under-ice vertical communication trial test.","PeriodicalId":429405,"journal":{"name":"Proceedings of the 13th International Conference on Underwater Networks & Systems","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115898976","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}

To solve this problem, this paper proposes a MIMO-FBMC system based on a subband cutting method. This scheme improves the performance of Alamouti space-time coded OFDM systems in underwater acoustic communication in the following aspects: First, FBMC modulation is introduced to reduce out-of-band leakage through a re-designed window. Besides, FBMC modulation can also increase spectral efficiency because it does not need extra cyclic prefix. Second, the subband cutting method provides more stable bit error performance, benefited from the nonoverlapping feature of channel effect. According to our simulation results for the Alamouti space-time coded OFDM system and subband cutting based MIMO-FBMC system, the latter can achieve better performance, especially in long time-delay underwater acoustic channels.","PeriodicalId":429405,"journal":{"name":"Proceedings of the 13th International Conference on Underwater Networks & Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127758113","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}
