LibyaSat-1 is a 300 kg mini satellite, which will be used to support high resolution multi-spectral earth imaging camera to fulfill the civilian needs. This satellite will operate at LEO of 775 km and will provide a resolution of 2.5 m for the panchromatic band and 10 m for the VIS/NIR bands with 30 km swath. We have presented the mission overview, mission operation concept and mission requirements. Moreover, the System Tool Kit (STK) simulation is used to show the ground trucks of LibyaSat-1 for three days and to find the contact numbers between LibyaSat-1 and both Murezeq and Tripoli stations. We have also presented the design of telemetry and command subsystem, code and data handling subsystem, electrical power subsystem, altitude orbit control subsystem, and structure subsystem.","PeriodicalId":371814,"journal":{"name":"2015 1st International Conference on Wireless and Telematics (ICWT)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130519065","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 interference impact is evaluated in a scenario where the wireless traffic light and RKE for vehicles operate on frequency 434 MHz and 433.9 MHz respectively. Three time delays 0 s, 0.2 s and 0.5 s were considered during the simulations. The results show that time delay 0 s and 0.2 s cause a very high probability of interference. Whereas time delay setting of 0.5 s provide probability of interference about 2 % at distance 5 m.","PeriodicalId":371814,"journal":{"name":"2015 1st International Conference on Wireless and Telematics (ICWT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130538072","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}

Simulation results show that the configuration of wider PCell bandwidth resulting better performance of the throughput.

Many earlier comparison method could sense the anomalous event, but not pay much attention to identify which flow was the anomaly. We presented residual calculation between windowed aggregate traffic statistical value combination. With residual calculation among statistical percentile 10th and mean, a high accuracy of flashcrowd and DDoS differentiation of synthetic anomalous event gained.

This paper aims at developing an application on the smart phone that receives program and transmits a request to the server as DVB-T transmitter. The target is to develop an application that allows smart phone interactively connected to DVB-T transmitter. As the first target we develop an android-based smart phone. We use DVB-T signal for downlink transmission and wifi for the uplink connection. This interactivity may include file sharing, polling, etc. using non-DVB enabler devices. Therefore the development of a system that can convert DVB signal into WiFi-IP based protocol signal is big challenge in this work.","PeriodicalId":371814,"journal":{"name":"2015 1st International Conference on Wireless and Telematics (ICWT)","volume":"363 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115974218","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 magnitude of PAPR caused the summation of power by the wave in phase so that maximum power compared to average power becomes high. One method to reduce the amount of PAPR is switching null subcarrier with the data subcarrier. This method has advantages over other methods that do not damage the transmitted signal. BER is not increasing and does not require any side information to restore the signal to its original data. The problem in the switching method is the complexity of the system. In this paper will offered a method based on switching data subcarrier null subcarrier.

To be able to answer these problems, a method called Software Defined Network (SDN) is being developed. The SDN concept is to separate the network's controller and forwarding plane of the hardware. In this research, SDN component, white box switch was built. To test its performance, RTT and throughput of some configuration were measured. The result is compared to conventional switch, which is Cisco Catalyst 2950. White Box Switch was created of a computer with 2.50 GHz processor and 32 GBytes memory. The result shows that performance of Cisco Catalyst 2950 is superior to white box switch because of its ASIC that allow it to forward data in hardware. Furthermore minimum specification of white box switch can be calculated, that is 1.225 GHz processor and 1 GBytes memory. To get the best performance, we can use single-board computer to be used as white box switch. Single-board computer contains all of its hardware in a single-board and it will give best performance of a computer.","PeriodicalId":371814,"journal":{"name":"2015 1st International Conference on Wireless and Telematics (ICWT)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130315163","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}

Secure information transfer can be achieved by cryptography and steganography. Cryptography is a tool that provides encryption techniques for secure communication. Steganography is the technique of hiding information by way of the message of the picture, so that in addition to the person addressed, another person will not be aware of the existence of the message. In this study the issues to be discussed is the technique of message encryption with RSA (Rivest Shamir Adleman) method. Messages are encrypted after compressed by LZW (Lempel Ziv Welch) method, so it will reduce the size of the message that will be inserted and increase the capacity of messages that can be inserted. Messages that have been compressed and encrypted, is then hidden by DCT (Discrete Cosine Transform) techniques. With the incorporation of encryption techniques, steganography, and compression, the acquired information is more secure and its capacity is larger. For a 512×512 colored image there are 1536 characters enable for hiding. With LZW the amount of characters hiding will be about twice larger in this research.","PeriodicalId":371814,"journal":{"name":"2015 1st International Conference on Wireless and Telematics (ICWT)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131567058","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}
