In sending messages via SMS, message security is essential in order to maintain the integrity of the authenticity of the messages. Messages are secured not only in the aspect of confidentiality, but also on how the delivered message is not altered by someone. To overcome these problems, digital signature is required. Elliptic Curve Digital Signature Algorithm (ECDSA) with Boolean Permutation (BP) is one of the algorithms used for the process of adding and verifying the digital signature on the message. ECDSA is a public key cryptographic algorithm that is suitable to be implemented on devices with limited resources such as, mobile device or mobile phone. This is because the keys of ECDSA have relatively smaller than other public key cryptographic algorithms. ECDSA and Boolean Permutation can be implemented on mobile devices based on Android, and be able to verify the authenticity and maintain the integrity of SMS sent with several characteristics, such as, SMS that contains of letters, numbers, emoticons with the length of SMS that can be authenticated is 4 SMS - long in one delivery process (long messages).","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"26 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126116875","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}

They are supposed to pass the desired frequencies and block or suppress the unwanted ones. Filter has been used widely especially in radar system. There are various methods to design a bandpass filter especially for higher frequency. Microstrip filter type is chosen in this research because its simplicity in the design and easy to be implemented. One of the method in designing a microstrip filter is Square Loop Resonator which also known as SLR filter. The filter that will be designed have center frequency at 9GHz with 50MHz bandwidth. The filter is planned to be printed on Rodgers Duroid PCB material with relative permittivity (ϵr) 10.6. Higher value of (ϵr) is used to make the filter dimension smaller. The result of this design is a SLR bandpass filter with resonator size 13cm X 13cm with the final PCB size of this filter is 30cm X 18 cm. The simulation result of this design has shown that the filter has center frequency at 9GHz and 55.2MHz bandwidth, 5.2MHz wider than had planned.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"21 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132069661","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 estimator does not need any a priori information about the signal. The simulation is done with the input of Digital Video Broadcasting - Terrestrial (DVBT) signal which passes through AWGN channel in two condition, ideal and real condition. The performances are given in normalized mean-square-error (NMSE) and noise uncertainty. It is shown a low value of NMSE.

An optical network topology typically has a ring topology; therefore, it can be modelled with the Travelling Salesman Problem. Furthermore, solution can be obtained from the TSP's model using heuristic method and get an optimal ring topology in a quick time. The quality and result of the topology result is based on the minimum weight value. This proposed algorithm will determine the starting point or set of links that are below some value and then will grow until every node are successfully passed or visited. This algorithm's quality is tested by comparing the minimum weight value with others algorithms such as brute force algorithm, ant colony algorithm, and another related algorithm. This proposed algorithm can produce a ring topology with a minimum weight value better than ant colony algorithm and the computing time is much faster than brute force.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128115456","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}

A genetic algorithm (GA) is employed to choose 62 out of 119 BTSs that has the maximum coverage. To get the best network planning, the optimization is done in both district and region area. Then, the optimization results are verified using Atoll to get the performance of the network.

Segmentation technique is a technique that divides the distance of the communication transmission range of a vehicle into several segments and do not overlap. There are two segmentation techniques namely uniform and non- uniform. However it does not answer the problem that the vehicle is a node with a very high mobility which can move quickly between segments. It requires the probability of packet collisions between vehicles should be same in each segment. Thus, this study makes a modeling segmentation technique which adopts modeling headway Distribution Semi Poisson which is called semi-uniform segmentation technique. This technique is expected to give boundaries in communication segment vehicles which can answer these problems. This study used several parameters such as traffic volume, speed data rate, and 3 VANET applications namely electronic emergency brake light (EEBL), approaching emergency vehicle (AEV) and traffic information (TI). The volume of traffic is divided into two, namely 300 vehicles/hour (low traffic) and 1,500 vehicles/hour (high traffic) while speed of the data rate is divided into two, 3 Mbps and 6 Mbps.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127155777","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}
