Since DTN was conceived to relax most of the assumptions associated with Internet protocols, the most important of which is the availability of an end-to-end path between source and destination for the duration of a communication session, it is possible to envision the application of DTN concepts to under-water acoustic networks, where the bandwidth-limited acoustic channel suffers frequent disruptions due to environmental factors. This paper presents the design and implementation of an Underwater Convergence Layer (UCL) for the DTN2 Reference Implementation, which provides DTN support for the WHOI Micro-Modem. UCL was tested in the field during the Acommsnet10 sea trial, in a heterogeneous context comprising underwater nodes communicating acoustically and surface nodes communicating with radio frequency. Initial results and lessons learned from field testing are also presented. The principal value of this development resides in the delivery of new capabilities towards the application of DTN concepts to the maritime domain, to enable functionalities like multi-hop acoustic communication, data mule using autonomous vehicles and gateways between different transmission media (e.g. between underwater acoustic communications and above water radio/satellite).","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125938012","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}

Relays exchange data and channel information with the base station to achieve diversity gains. Due to non orthogonality of random spreading waveforms, Multiple Access Interference occurs, at both the relays and base station. In order to mitigate Multiple Access Interference, Adaptive Multiuser detection is been used by fractionally spaced linear transversal bank of filters. It is shown that Adaptive Multiuser Detection enables asynchronous cooperative communications while it is extremely effective with mitigating channel interference. It is also shown that the BER and Capacity performance of the scheme proposed in this paper is arbitrarily close to non linear MLSE theoretical upper bound results in a channel interference free operation. However, in the presence of channel interference our scheme outperforms the theoretical upper bound approach by nearly 9 dB at a BER of 10−3 and by 17 bits/s/Hz in Capacity at a SNR of 30dB.","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129761510","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}

Few attempts addressed this problem, all of them under controlled scenarios, avoiding the complexity of real-world connectivity. As a result of our comparison of selected networks under a wide variety of realistic scenarios, we have not only been able to identify and describe favorable traits of protocols, but also necessary relationship of successful MON protocols with QoS routing in wired networks. We present a novel protocol, Nile1, that performs both in dense as well as sparse networks. Nile is the first autonomous “controlled Hooding” protocol that keeps the link loads in check, to push replicas only on those paths that are both promising and may sustain more load. It is a multi path protocol that deploys replication based on heuristic for disjoint path calculation. Other protocols' performance, when simulated in real-world traces, highly depends on parameter choice. Nile, however, consistently performs among the top protocols without any external tuning and exerts far less overhead than other replication protocols.","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114259244","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}
