Choosing the appropriate propagation model for a specific environment requires extensive analyses. The ray tracing 3D shoot-and-bounce ray (SBR) technique employed by Wireless InSite software is adopted in this work to simulate the signal propagation and evaluate its strength. Three indoor scenarios with two cases each; Line of sight (LOS) and non-line of sight (NLOS) are being simulated and tested. The test bed was conducted based on Net Spot software. The Basic objective is to compare the measured and simulated received power in order to introduce the potentials and limitations of using ray tracing to characterize the indoor wireless channel at 2.4 and 5 GHz. The comparison results show an acceptable correlation between experimental and simulation results. The effects of distance, frequency, and obstacles materialized by different furniture features have been investigated. The nodes that are located in LOS at room B outperforms the NLOS nodes which are located at room A by (3 dBm) in terms of mean received power for both frequencies. Long distance contributes significantly in signal strength reduction, where minimum received power equals to (-77 dBm) at 5 GHz is noticed at the corridor due to long distance. In addition, 2.4 GHz case verifies better signal quality due to less path loss, and the corridor scenario gains less difference between both frequencies. The office scenario achieves the minimum Mean Absolute Error (MAE) between experimental and simulation results at both 2.4 and 5 GHz.","PeriodicalId":375095,"journal":{"name":"Proceedings of the International Conference on Information and Communication Technology - ICICT '19","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122562288","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}

Brain signals are recorded using many methods. Electroencephalogram (EEG) is one of the non-invasive methods. EEG signals are recorded using multiple channels. Selection methods are used to choose the most relevant and powerful signals. Usually Meta-heuristic algorithms are used for selection. Meta-heuristic algorithms depends on random generated population of solutions for the objective function. Because of the randomness, there is always a chance to select zero as a solution. Zero in EEG channels selection means no channel is chosen to extract its signal features. This situation is not practical, the selection process should be repeated whenever a zero solution appears. The repetition will reduce the algorithm speed. This paper introduces a fast channel selection algorithm using Crow Search Algorithm (CSA). CSA is used to select the best channels offline. Using no-zero channel condition to fasten the algorithm. Our results show that CSA with no-zero channels condition is better than Genetic algorithm (GA). Although CSA and GA results are almost have the same accuracy, but CSA with no-zero condition is faster.","PeriodicalId":375095,"journal":{"name":"Proceedings of the International Conference on Information and Communication Technology - ICICT '19","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122984064","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}

Efficient utilization of limited energy supply of sensor nodes is one of the key design issues in wireless sensor networks. Hence, energy efficiency needs to be enhanced to prolong the stability and lifetime of WSN. In this paper, we propose Energy-Efficient Clustering Protocol based on Energy Intervals (EECP-EI) for multi-level WSN. EECP-EI associates sensor nodes to clusters based on energy intervals. The cluster heads are selected based on average energy of certain energy interval and the total estimated energy of network at a particular round. The role of cluster head is rotated within the cluster to evenly distribute the energy among sensor nodes inside the cluster. The sensed data is aggregated at the cluster head to reduce the amount of data that needs to be communicated to the base station. The sensed data is communicated to the base station using hierarchy of cluster heads that are in ten-meter distance to the sending cluster head. When the cluster formation no longer remains optimal, every sensor node in the network transmits data directly to the base station. Simulations show that EECP-EI shows the improved stability period of 37.08%, 36.37%, and 19.39%, and the improved network lifetime of 6.58%, 13.13%, and 32.15% as compared to LEACH, DEEC, and DDEEC respectively.","PeriodicalId":375095,"journal":{"name":"Proceedings of the International Conference on Information and Communication Technology - ICICT '19","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129106303","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}

SDN has shown great potential to simplify the existing complex, inflexible, and costly network architecture and infrastructure through the reshaping of conventional network functions and design of the protocols. To achieve this goal, OpenFlow protocol has been proposed and is considered the most widely deployed protocol in the field of SDN technology. Mininet emulator provides an efficient virtualization method to design and study the SDN concepts with different types of software switches and controllers. In this research, an extensive study about the effects of changing the size and type of network topology that is constructed in Mininet's virtualization environment presented, in addition to the effects of the types of SDN switches and controllers used to build the network on the amount of resources that must be provided by the operating system. The results showed that there are differences in performance for the controllers and switches, where the OVS controller utilized the higher processing power for Open vSwitch than that of User-Space switches. The later type of switches consumed vast amount of system memory during the construction of large size topologies. The use of Open vSwitch also, resulted in more setupteardown time, which was almost twice that of User-Space switches in large size topologies.","PeriodicalId":375095,"journal":{"name":"Proceedings of the International Conference on Information and Communication Technology - ICICT '19","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127395136","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}
