In IoT ecosystem, Machine Type Communication (MTC) is the access technology that ensures wireless connectivity for end-user devices to the network. Diverse IoT applications pose conflicting requirements and challenges that must be resolved to fully realize the IoT ecosystem. Although the right access technology to address all these challenges is not available yet, notable progress has been made in the recent times to address most of the key requirements. Extended Coverage (EC)-GSM-IoT and Narrow Band (NB)-IoT have been standardized by 3GPP in Release 13 as the access technologies for IoT. Among non-3GPP community, Long Range (LoRa) has attracted significant attention. In this paper, the suitability of the aforementioned access technologies to various IoT services in terms of the relevant system parameters is explored. We have also identified many system design parameters that will have adverse implications if not configured correctly for the right IoT use case. Important open challenges to be addressed from physical layer (PHY) perspective are highlighted here that will help to realize a truly connected world.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123546934","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}

Modulation classification is an intermediate step between data detection and its demodulation for extracting the final information. Proposed method estimates the carrier frequency offset after downconversion of passband signal with estimated carrier frequency and corrects for it. Signal is sampled with high frequency and symbol rate is estimated. Sampled signal is downsampled to estimated symbol rate to extract the constellation points. For identification of modulation scheme between QAM and PSK of different orders, k-medoids clustering is used. Blindly, k medoids are estimated for k equals to 4, 8, 16 and 64 and similarity to ideal constellation structure is calculated. Final decision for modulation scheme is given in favor for which similarity with ideal constellation structure is maximum. The simulation results for the method shows that different modulation schemes are classified efficiently above 10 dB SNR in presence of Additive White Gaussian Noise. Method proposed is unsupervised and has low computational complexity.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124340305","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}

These adversities hinders the flows to meet their associated deadlines and ultimately the service level agreement (SLA). There are two classes of solutions proposed for the problems of congestion and meeting deadlines for the flows - a congestion control at the transport layer and resource allocation at the network layer. The proposed solutions at the transport layer modulated the TCP window size according to the extent of congestion and the deadline value associated with the flows. These solutions are proposed based on the assumption that the intermediate switches maintain soft-state about the flows. Thus, the entire flow has to follow a static path from begin to end.Contrast to this, the location based routing proposed for DCN tries to utilize the path diversity provided by the underlying architectures by distributing the flows among all the available outgoing paths using the Equal Cost Multiple Paths (ECMP). In this paper, we propose a packet scheduler that helps the flow to meet their associated deadline. We consider our proposed $4-4,1-4$ architecture as an example architecture for location based routing. Packet scheduler for $4-4, 1-4$ helps the flows to meet their deadline by arranging the packets at the intermediate switches according to their associated deadlines. With prioritizing and scheduling the packets at the network layer, the flows are not constrained to assign to a static path and the intermediate switches need not to maintain any flow state information.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124031158","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}

Currently in the scenarios of diverse bandwidth requirements for next generation optical communication systems, a novel Dynamic Base Unit (DBU) unequal channel (US) allocation strategy is designed, and the performance benefits are investigated over the traditional existing Fixed Base channel allocations. The proposed algorithm decides the total number of base units covering the optical bandwidth. After the channel allocation in the first base unit $BU_{i=0}$ the current work discusses the case of reducing the number of channels in subsequent Base Unit $(BU_{i=1,2,..})$ by a factor of 2. Moreover, the adjacent base units are allotted even and odd frequency slots. Thus, this is an optimum strategy where maximum non-uniformity is taken care of in channel allocations. This drastically reduces the nonlinear effects of Four Wave Mixing (FWM) prominent in DWDM systems using Dispersion Shifted Fibers. The proposed algorithm is evaluated in terms of the bandwidth occupancy and number of Four Wave Mixing products. Performance up to greater than 34.6% reduction in FWM is observed. Bandwidth occupancy shows 13.7%, 6.25% and 7.45% reduction than the popular Unequally Repeated US(URUS), Paired URUS and Alternately Paired RUS (PURUS) schemes respectively. The high improvement factor is observed when using DBU-US. It is concluded that Dynamic Base Unit-Unequally Spaced channel allocation is superior and is considered a suitable candidate for high speed DWDM transmission systems.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125096260","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 enhance the achievable rate of VLC systems, the use of massive arrays of light emitting diodes (LEDs) and photodetectors (PDs) have been recently proposed, resulting in a massive multiple input multiple output (m-MIMO) VLC system. Furthermore, orthogonal frequency division multiple access (OFDM) has been explored for mitigating the inter-symbol interference due to limited modulation-bandwidth of the LED, and reflections from walls. One of the drawbacks of m-MIMO over VLC channels is the ill-conditioned nature of the VLC channel. To mitigate this, a zero-forcing successive interference cancellation (ZF-SIC) receiver with SVD (singular-value decomposition-based index precoding has been proposed recently. In this work, we propose and analyze the performance of minimum mean squared error (MMSE) based receiver for DC-biased O-OFDM (DCO-OFDM) for a m-MIMO VLC channel. Simulations performed over various m-MIMO VLC channels indicate that the derived analytical expressions for BER closely match with the simulated BER. Furthermore, MMSE-SIC is found to outperform ZF-SIC, which makes the proposed receiver viable for potential VLC deployments.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127347945","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 particular, considering the inherent non-linearity in a radar system, KAF has been recently applied for estimation of delay and found to achieve lower variance as compared to classical Fourier-Transform based approach. However, as the radar-return is complex-valued in general, using a traditional complex Gaussian kernel in KAF based estimator yields inaccurate estimates. In this work, we explore Wirtinger’s calculus-based complexification of a reproducing kernel Hilbert space (RKHS) for estimation of delay and Doppler-shift, which guarantees lower estimator-variance, and kernel-stability. Furthermore, since the choice of suitable kernel-width is crucial for RKHS-based estimation of delay and Doppler parameters, we derive an adaption for joint-estimation of kernel-width for the proposed normalized complex kernel least mean square (NCKLMS) based estimator from the radar return. Simulations performed over orthogonal frequency division multiplexed (OFDM)-radar system indicate that the proposed NCKLMS based estimator converges to a significantly lower dictionary-size, thereby leading to simpler implementation, receiver-simplicity, and latency whilst maintaining equivalent squared error performance, which makes the proposed estimators suitable for practical OFDM-radar systems.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126712725","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 context, a weather monitoring technique inspired by the extent and efficiency of sensors on insect antennae is presented. Antennae are a subject of current heuristic intrigue and have motivated robots and sensors with applications ranging from material characterization to chemical volatility and tactility. This approach is taken a step forward by implementing an integrated sensor network, simultaneously picking up variations in pressure, temperature, relative humidity and wind speed. The basic construction and operating principle of the sensor is inspired by the pressure detecting element, the Campaniform Sensilla, on insect antennae. This hypothesis is supported by a set of equations relating the various factors. Then the model is tested for sensitivity, effectiveness of integration and feasibility. Multi– sensing is deemed desirable in smart cities, where sensory overload and the resultant power shortage are likely to pose major technical hindrances. This device promises compactness combined with accuracy and precision and can be implemented anywhere from next - generation cars to airplanes.","PeriodicalId":273443,"journal":{"name":"2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126348711","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}
