We utilized the Kano Model to map those attributes into customer satisfaction analyses. The survey was conducted among respondents in the Jakarta market area, asking about the satisfactory expectations of ten service attributes. These range from security aspects to the mobile handset performance. The aspects that have the greatest influence on customer satisfaction in 4G service are wider coverage areas and signal stability. However, Indonesian customers have not yet shown enthusiasm for using Internet of Things. It is necessary for Indonesian telecom operators to educate the market, preparing their customers for the coming of Internet of Things. Our work presents a novel contribution to the Indonesian mobile network operator for developing concurrent market strategy.","PeriodicalId":328054,"journal":{"name":"2017 International Conference on Control, Electronics, Renewable Energy and Communications (ICCREC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130387600","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}

To overcome that problem, the “Store-Carry-Forward” paradigm is chosen, the paradigm is used to carry the message received by a node to other nodes. In that process, buffer is involved on each node and the process needs a buffer management on each node to increase the delivery probability and decrease the drop on message. On this paper we will be implementing the Message Drop Control Source Relay (MDC-SR) buffer management on MaxProp routing. MaxProp has a low performance using a small buffer. The scenario used in testing the performance of MDC-SR is by using some Upper Bound (UB) in the MDC-SR scheme using the Shortest Path Map Based Movement with random message size.","PeriodicalId":328054,"journal":{"name":"2017 International Conference on Control, Electronics, Renewable Energy and Communications (ICCREC)","volume":"40 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130171559","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}

First of all, the data is processed by Weighted Moving Average (WMA) algorithm as preprocessing step. Next, GP Algorithm is used to process the rainfall weather forecast which represents non-linear chromosome as a tree. In a population, chromosomes have different lengths because a child's chromosomes can be longer or shorter than his parents. To produce child, GP Algorithm applies the recombination process and the mutation using the several scenarios of probability of crossover and probability of mutation.

The results showed that the perceptual quality of audio in the form of ODG (Objective Difference Grade) and SNR (Signal to Noise Ratio) parameters for DWT (Discrete Wavelet Transormation) level 1 was higher than level 3. It can reach ODG level 1 = −0.68 and level 3 = −1.54 on LSC attack type; SNR level 1 = 31 dB and level 3 = 27 dB on LPF attack type. While for watermark image BER parameter, the result of the research shows that BER level 1 is worse than level 3, which can reach BER level 1 = 0.35 and level 3 = 0 on LPF attack.
