Experts have been speculating about the demise of the phone number for some time and with the widespread emergence of communication OTTs the general expectation has been that the phone number will soon lose its original functionality as a communication endpoint on the PSTN. Our research suggests, however, that the phone number is not set to go extinct in the medium term but is more likely to evolve into a unique and core element of digital identifying technologies for a wide range of online services, and is thus likely to retain it's significance for at least another decade or so.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132985724","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}

Millimeter wave (mmWave) communication has been considered as a promising solution for future capacity crunch due to large available bandwidth. However, an outdoor macrocellular layer lacks the capability of providing an adequate coverage to indoor users, especially at higher frequencies i.e. 28 GHz. Therefore, the provision of high data rates and high system capacity in an indoor environment requires a separate indoor solution. The main target of this paper is to analyze the performance of Ultra Dense Network (UDN) and Distributed Antenna System (DAS) deployment in an indoor (university office) environment at 1.8 GHz, 2.6 GHz, 3.5 GHz and 28 GHz frequency. This research work is conducted by performing a ray tracing simulation using a three dimensional floor plan. The obtained results show that the existing indoor solutions which are in operation at 2.6 GHz can be reused at 3.5 GHz frequency with minor power adjustment, or by using antennas with little higher gain. However, the operation at 28 GHz requires a new plan for providing good indoor coverage. Acquired results show that DAS improves the cell capacity by reducing the interference. However, the UDN provides a higher system capacity due to more number of cells. The real gain of operation at 28 GHz can only be achieved by using larger system bandwidth e.g 200 MHz band.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122540455","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}

One of the cornerstones of the architecture is a Thing Description, which is an object model that exposes devices to the Internet through a common interface composed by properties, actions and events. In this paper, we evaluate the similarity level on capabilities calculated for Web of Things objects. We developed, based on the Thing Description, a metric called Web of Things Semantic Functionality Distance (WoTSFD). The semantic functionality distance is a measure of the device ability to perform the same function in a specific application context. We evaluate this metric in a smart home environment. The results show that different devices can be detected to be similar, thus suitable to collaborate or be replaced by each other to perform a specific task in a determined use case.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124741716","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 missing information should be restored using only a minimum knowledge of the data. Compressive Sampling (CS) algorithm provides a solution to complete data by utilizing the properties of randomness in the input data. Recently the reconstruction algorithm has developed in the base dictionary using orthogonal based operators. In this paper, we consider a CS approch to solve the missing problem using Singular Value Decomposition (SVD) sparsity, routing matrix for measurement matrix, and Orthogonal Matching Pursuit (OMP) as a recovery algorithm. To improve the accuracy, we also incorporating linear interpolation after OMP and Bilinear interpolation after SVD reconstruction. The missing scheme is randomized to simulate the actual behaviour of the network. Our experiments show that our proposed method is capable to fix large missing values with a high degree of accuracy for all missing type. This method is superior compared to the method in previous studies.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123611938","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}

Plasmonic material Gold (Au) and sensing layer are placed outside the fiber for attaining practically feasible detection mechanism. A thin layer of titanium dioxide (TiO2) is employed as an adhesive layer in order to attach the plasmonic material with silica glass. In the sensing range of 1.00 to 1.37, maximum sensitivities of 20000 nm/RIU and 811 refractive index unit (RIU)−1 are obtained with resolutions of $5times 10^{-6}$ and $1.43times 10^{-5}$ RIU using wavelength and amplitude interrogation method, respectively.

However, it is difficult for IA to achieve the desired effect in practice since the channel state information at transmitter (CSIT) is always limited. In this paper, an extended blind interference alignment (eBIA) is proposed to enhance the performance of multi-cluster networks without CSIT. The theoretical analysis indicates that the proposed scheme can cancel the inter-cell and intra-cell interferences by relying on the single reconfigurable antenna of users. Meanwhile, this paper gives the relative comparisons with other existing algorithms on degree of freedom (DoF) and sum-rate. The simulation results demonstrate that the proposed scheme does indicate the better performance.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131741540","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}

However, practically implementing such systems is challenging as they suffer from high hardware complexity and power consumption. Analog beamforming is considered as one suitable approach for practical implementation of such systems, relaxing the hardware and power consumption requirements compared to full digital beamforming solution. Moreover, hybrid beamforming solutions emerged as an attractive solution that can capture the trade-off between digital and analog ones. In this paper we mathematically show that in pure Line of Sight (LoS) channels, using hybrid beamforming with Zero Forcing (ZF) at the baseband can achieve equivalent Spectral Efficiency (SE) compared to the full digital ZF precoding, with lower hardware complexity, and lower power consumption. Moreover, we validate the equivalence in SE performance between hybrid ZF and digital ZF by simulation results.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133314637","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 these technologies, such as Low Power Wide Area Networks (LPWANs), are non-IP due to the difficulties of using IP on constrained devices. These nodes are characterized by more constraints with respect to other IoT technologies. According to [1], IPv6 offers many benefits for IoT, which motivated the IETF to form a Working Group (WG) to study and propose new solutions to run IPv6 on the new technologies of IoT [2], [3]. The key to solving this issue is the header compression mechanisms. In this paper, we analyze the two IETF standardized solutions, SCHC and 6LoWPAN, to compress IPv6 over constrained nodes within LPWAN. Based on [3], we implement the SCHC mechanism [4] in the network simulator NS3 [5]. We also show that SCHC protocol solution as an adaptation layer between the network layer and the link layer is better in term of header compression by providing a smaller header size compared to 6LoWPAN.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131331275","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}

While the course is targeted at graduate students in Electronic and Electrical Engineering (EEE) and Computer Science (CS), our student cohort is very diverse with students having completed their first degree in fields such as Physics, Telecommunications and Information Technology. A unique feature of the course lies in strong collaboration with key industrial partners, some being actively involved in the course delivery.
