The Steepest Ascent Hill Climbing algorithm is applied to determine the optimal shape of the crossword board. The initial successor is selected by the most number of characters, the next succcessor is selected from the second longest character until all the answers are selected, then in the final step is to calculate the fitness value to evaluate the answer board formed by calculating the answer junction and the number of questions that can be used on the answer board. Testing in this research is done by testing the same number of columns and rows by obtaining the amount of fitness value that is not too significant different, this explains that the crossword board can be made.

The use of a 13.56MHz crystal and a 74HC04N CMOS integrated circuit (IC) as main parts of oscillator is aimed to have a stable sine wave generator in compact configuration. In order to have good impedance matching, a common collector BJT amplifier is applied as an impedance matching circuit. The oscillator as well as the impedance matching circuit are deployed on a single layer of FR4 epoxy dielectric substrate with the thickness of 1.6mm.

An important component that can improve the performance of a radar system is the filter. The function of the filter is to pass the desired frequencies and block the unwanted frequencies. This study discussed the design and realization of a bandpass filter using microstrip technology with a hairpin structure working at some parameters, namely frequencies, bandwidth, insertion loss, return loss and VSWR. The filter was realized using a Rogers 5880 substrate with a relative dielectric constant value of two point two and substrate thickness of 1.58 mm. A simulation was carried out using the CST Suite Studio software application.

The existence of tappers to make information can be known by unauthorized parties, and it will give a fake information from the previous one. As technology develops, secure communication protocols become an important part. Quantum Key Distribution is a nowadays technology as a part of security improvement to overcome key distribution issues in against attackers. Quantum Key Distribution (QKD) uses a quantum property in exchanging information called photons, as carriers of information in security systems. QKD is inseparable from protocols BB84 and B92, therefore the purposes of this paper are to test QuVis based on future work of previous research, analyze the probability error comparison of BB84 protocol, B92 protocol and simulator software review. The results of this research show that B92 protocol gives more advantage in detecting eavesdropping in lower rates than BB84 protocol and the software simulation is succeed by showing the value of probability key that can be used by Bob which does not cross the limit (0.5 and 0.25).","PeriodicalId":356888,"journal":{"name":"2018 4th International Conference on Wireless and Telematics (ICWT)","volume":"395 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131646025","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}

LEACH algorithm is divided to setup phase and steady state phase. In a busy network, LEACH Routing has a high packet loss. To solve the problem we need Delay Tolerant Network (DTN). DTN is an advanced architecture that allows communication in extreme conditions like a busy network. In this research, LEACH-WSN changes to optimize the network by adding DTN to LEACH-WSNoverDTN. The LEACH-WSN modification by providing a bundle layer to keep the data temporarily. Simulation is performed to test the performance of LEACH-WSNoverDTN based on changes in the number of node and buffer capacity. In changing the number of node, LEACH-WSNoverDTN can improve performance by decreasing packet loss value by 50% of LEACH-WSN packet loss. In changing of the buffer capacity, LEACH-WSNoverDTN also improves performance on PDR values that increase by 1.8% of LEACH-WSN. In the test of energy consumption in two scenarios, LEACH-WSN and LEACH-WSNoverDTN have no significant differences but when we check the lifetime of node which depends on energy consumption, LEACH-WSNoverDTN has early death node. The effect of LEACH-WSNoverDTN is significant when the number of nodes increases or busy network.","PeriodicalId":356888,"journal":{"name":"2018 4th International Conference on Wireless and Telematics (ICWT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127163814","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}

Ergodic sum capacities of the proposed cases are provided for independent Rayleigh fading channels. It has been demonstrated that the proposed protocol exhibits superior performance gains than the existing cooperative relaying scheme (CRS) using single-input-single-output NOMA, CRS using multiple-input-single-output NOMA, and conventional CRS MIMO protocols. It is also noticed that the relay position between the transmitter and the receiver can bring a vital change in the performance of the proposed network.","PeriodicalId":356888,"journal":{"name":"2018 4th International Conference on Wireless and Telematics (ICWT)","volume":"38 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131235566","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}
