Billions of things are expected to be a part of IoT paradigm in the near future, providing enormous applications ranging from home automation, smart environment, health care, etc. One of the major hurdles for IoT to be effective with existing network architectures is a prolonged and seamless connectivity between the things and with the end user. Due to heterogeneity in the characteristics of Wireless Sensor Network (WSN), it has become a most prominent technology to bind the things with the Internet and with the end users. Wireless Sensor Networks are self healing and active in nature, that is, they can sense, instruct, request, respond and can easily be adopted to Wireless Sensor and Actuator Networks (WSAN). Addressing scheme in Wireless Sensor networks has to be foreseen if it has to be deployed in Internet of Things paradigm. This paper proposes a discrete cluster based addressing scheme on IEEE 802.15.4 standard for all the things included in a Wireless Sensor Network based IoT applications. Results have been evaluated with existing IPv6 based addressing and it is found that cluster based addressing scheme on the traditionally used IEEE 802.15.4 communication channel suits well over the end to end IPv6 communication channel.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114806996","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 testbed is designed in Field Programmable Gate Array (FPGA) in order to provide maximum flexibility in implementation. A modularized design approach is adopted which enables easy implementation, Integration, and testing algorithms of various physical layer modules of OFDMA. The entire physical layer design is successfully implemented in a single Virtex-4 FPGA processing core. The designed testbed architecture features up to 2×2 MIMO implementation with different MIMO modes and Frequency Domain Link Adaptation (FDLA). However, It is also discussed that the design can support up to 4×4 MIMO implementation depending on the choice of PHY design parameters such as FFT Size and FPGA processing frequency. The design is shown to be flexible and reconfigurable to work with different configurations using minimal PHY layer design alterations. The real-time over the air performance results are obtained using over-the-air transmission and reception of data traffic through the testbed. Finally, over-the-air performance results of the testbed are calibrated with the simulated performance over the SUI-3 channel. The implementation is performed on Wireless Open-Access Research Platform (WARP). LTE Release-10 parameters are adopted for designing the testbed.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128280794","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}

With bandwidth-intensive on-line applications such as video, music, and voice the demand for higher data rate increases. The ever-increasing data rate demand will be supported by multilevel signaling over fiber-optic links in the backplane. Traditional coherent optical links use the power hungry ADC+DSP approach at the receiver side for mitigating the distortions caused by the system non-idealities. A significant amount of power consumption can be reduced if the received signals are processed in the analog domain itself. This paper presents a 12.5GBd 16-QAM analog processing-based coherent receiver, that has been designed and simulated using 130nm BiCMOS technology. The receiver uses radius directed equalization and Costas loop based carrier phase recovery and compensation. Simulations indicate that the receiver is capable of mitigating a dispersion of up to 160 ps/nm and a frequency offset of up to 10 MHz. For a transmission over 10 km-long fiber the receiver gives an output error vector magnitude of 23.2% when the laser linewidth is 200 kHz. The receiver is projected to consume ~3.5W of power.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128297461","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 existing modulation classifiers assume the signal to be contaminated only by additive white Gaussian noise (AWGN). However, the performances of these traditional classifiers degrade in the presence of non-Gaussian impulsive noise. In this paper, we present a novel automatic modulation classification algorithm based on variational mode decomposition (VMD) in presence of non-Gaussian impulsive noise and additive white Gaussian noise. Our proposed method is a three step process. In the first step, received signal is decomposed into modes. It is clear from simulation results that impulse noise is effectively captured in the first mode. In the second step, all other modes are added except first mode to reduce the impact of impulse noise in the received signal. Then in the third step, cyclostationary feature based classifiers are employed to identify the modulation type. The proposed algorithm is evaluated using well-known existing classifiers for different digital modulation techniques. Comparative results depict the superior performance of our proposed method over other traditional methods under different noise conditions.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116229009","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 paper, we derive expressions for outage probability and bit error rate of two-hop relaying systems incorporated with transmit antenna selection at source and relay node. A closed form expression for outage probability and an infinite expression for bit error rate are derived for two hop cooperative communication system for BPSK modulation scheme. In the analysis, received signals are assumed to be collection of signals received as a result of multiple reflections having a line of sight component. Such channels can be well approximated by κ-μ fading distribution which is generalized assumption to model fading channels with a dominant or line of sight component. To analyze the performance of the system at high SNR conditions, the expression of asymptotic BER is also derived in closed form from the expression for exact BER. The transmit antenna is selected at the source and relay nodes such that the received signal to noise ratio at the destination node is maximized. Maximal ratio combining is considered at the relay and destination nodes. The bit error rate results obtained from analytical expressions and Monte Carlo simulations are plotted for different values of fading parameters, κ and μ. The analytical results are found to be in close agreement with simulation results.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130745766","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}
