Nodes in the same grade follow a synchronized duty cycle to transit from the different operation modes (transmission, reception, sleeping). In order to transmit packets from one grade to the next, nodes use pipeline scheduling to coordinate transmissions between adjacent grades. During a transmission slot, H-MAC employs hash functions to implement a distributed election whose winner can access to the channel in an interference-free fashion. Extensive simulation results show that H - MAC outperforms state of the art proposals in terms of throughput, source-to-sink packet delay, packet loss probability and energy consumption. This is particularly true in scenarios where the LSN has from medium to high node density, which is a common condition in the context of the IoT.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131126378","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, for these applications is essential that their parameters are suitable. Besides, the theoretical design of this type of antennas is not always effective. So, the metaheuristic optimization algorithms combined with simulations are presented, as a very efficient tool for the design of this class of antennas. Swarm intelligence is imitated of organisms present in nature that have an organization to each other and this communication between members of the same population makes it possible to find a global optimum value of the parameters. In this paper, metaheuristic swarm intelligence optimization algorithms have been used for the design of patch antennas. The optimization techniques used were particle swarm optimization, firefly algorithm and directional bat algorithm. The optimization of the operating frequency, the reflection parameter or Sl l and the impedance of the antenna is performed. Each algorithm performs the search in a different way. Finally, the results obtained are presented.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123687288","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}

Specifically, the symmetric models are applied in the $I/Q$ imbalance testing area, while the asymmetrical models have applications in the $I/Q$ imbalance calibration area; each model offers advantages in their respective areas, with applications in real systems. In this paper, a study of both types of modeling was carried out, covering main characteristics, advantages and differences between these models. Symmetrical and asymmetrical models in matrix form are developed for transmitter and receiver bearing on a zero-IF architecture, taking into account the main sources of imbalance in the analog front end (AFE). Based on these models, a matrix model transformation methodology is developed, which is capable of transferring the $I/Q$ imbalance characteristics of a symmetric model into an asymmetric model. Simulation results confirm the proposed model transformation through a performance comparison of four $I/Q$ imbalance testing algorithms in the sense of the AFE imbalances estimation, allowing a fair comparison under the same conditions of imbalance.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124587302","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}

This algorithm has low complexity and is robust under nonuniform noise. This paper analyzes the performance of the CF-CPSC under quantized and erroneous report channel transmissions. Two approaches has been investigated regarding the CF-CPSC test statistic: i) it is completely computed at the fusion center (FC), and ii) it is partially calculated at each CR for saving report channel resources. In both cases, the information to be reported by the CRs are uniformly quantized and then submitted to errors. Results show that the CF-CPSC is also robust to the quantization and report errors. The second approach is more sensitive to the quantization and report channel errors, but less channel resources are used in comparison with the first approach. The smaller resource usage is achieved by the second approach even with error correcting codes, which increases the amount of data through the report channel. The resource usage achieved by the first approach is larger, even with no error correcting codes.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114937359","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}
