The application scenarios mainly include radio over fiber (RoF), microwave-photonics (MWP) and optical wireless communication (OWC) systems, forming a large-capacity and broad-band wireless communication system. In this paper, we give a brief introduction of our recent research efforts on the optical technologies for wireless communications. In RoF systems, we have proposed two highly-compressed mobile fronthaul schemes for effective and large-capacity transmission in wireless access networks. In MWP systems, we have proposed self-interference cancellation of in-band full-duplex (IBFD) schemes for broadband and effective wireless communications. In OWC systems, we design a novel bidirectional full-duplex RF/free space optics (FSO) wireless access and backhaul architecture aided by optical technology for high-capacity wireless communications.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124878808","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}

Such waveforms could also be used to optimize performances of IIoT communication networks such as wireless and powerline communication networks. The C28x digital signal processor (DSP), manufactured by Texas Instruments is used as a case study, and it is deployed in this paper as a mother wavelet generator by programming it to generate needed wavelets using embedded C programming language. Our implementation is the first known application of the C28x as a basic mother wavelet generator. Advanced signal processing method which include signal clipping, sequencing and concatenation are used with embedded C to program the C28x DSP. Wavelets generated with the C28x DSP are found to satisfy the wavelet admissibility condition. The open-loop voltage signal of an IIoT machine, generated at an IIoT network edge, and sent across a powerline communication (PLC) channel is used to evaluate the performance of the constructed Mexican Hat wavelet. The Mexican Hat wavelet constructed using the C28x DSP is used to remove noise from the machine signal corrupted with noise when the signal is transmitted over a PLC channel. Denoised signal using the DSP based Mexican Hat wavelet shows high correlation when compared to the original transmitted signal, while communication channel noise is successfully removed from the original signal.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134491960","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}

Because the setup of an optical channel usually takes a long time, which may lead to a high rejection of connections that require low delays, routing algorithms should be properly designed to consider the limitations of optical devices in the hybrid networks. This paper focuses on the routing problem of the datacenter electrical/optical hybrid networks, and proposes an integer linear programming (ILP) model for the problem. In addition, a heuristic algorithm is also invented for large scale problems. Simulation results show that the heuristic algorithm can obtain a close performance to the optimal solution of the ILP method.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133908063","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}

The main obstacle preventing the heavy deployment of the P2P topology is the Network Address Translation (NAT) which serves as a solution for the exhaustion of IPv4 addresses. Methods proposed by the Internet Engineering Task Force (IETF) to solve the NAT traversal issues include Simple Traversal of UDP through NATs (STUN) and Traversal Using Relay NAT (TURN). STUN is limited by the type of deployed NAT, and TURN is limited by the peers' discovery mechanism which is application dependent. In this paper we propose a Blockchain-based platform that enables TURN servers to act as relays for Internet of Things (IoT) devices behind NAT. It also provides End-to-End (e2e) security for Constrained and Non-Constrained IoT devices. Results showed that the system has minimal impact on the existing network and can be a potential solution for advancing IoT deployment.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129654105","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 scheme, the amplified spontaneous emission (ASE) noise is used as the optical carrier to hide the signal both in time and frequency domain. The coherence length of the ASE noise is pretty short so that it is extremely difficult for an eavesdropper to intercept the signal. Only one Mach-Zehnder interferometer exists in the receiver, and there is no need for the receiver to match the optical delay. By this way, the optical delay and the polarization fluctuation caused by the environment can be automatically counteracted in the returning path. Therefore, no key distribution is required, and the optical delay value can be changed dynamically as a secret key in the receiver. In our experiment, 1Gb/s encrypted on-off keying signal is securely transmitted over 25km standard single mode fiber and dispersion compensation fiber.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127863142","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}

QC or more specifically quantum key distribution (QKD) promises unconditionally secure protocol, the Holy Grail of communication and information security, that is based on the fundamental laws of quantum physics. In this talk, we will discuss our latest experiments on a four-state (Quadrature Phase Shift Keying ‘QPSK’) RF sub-carrier assisted continuous-variable quantum key distribution (CV -QKD) multi-user network based on ultra low loss quantum channel (pure silica core fiber ‘PSCF’) and micro-electromechanical systems (MEMS) based add/drop switch. A coherent receiver with local local oscillator (LLO) is implemented, which ideally could not be accessed by eavesdroppers (Eve), aided with digital signal processing (DSP) module for phase noise cancellation (PNC). With 10 Gbit/s QPSK classical WDM signals, we have recorded secure key rates of 8.65 Mbit/s over 20 km and upto 12 Mbit/s over lossless channel. The experimental setup is further extended to a optically switched multi-user network, i.e. multiple Bobs, for implementing add/drop operations to achieve key rates of 5.98 Mbit/s for a 2 _2 MEMS switch. It is expected that the proposed cost-effective and energy efficient QKD network can facilitate the practical application of the CV -QKD protocol on commercial scale in near future for smart access networks.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127867705","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}
