In this paper, elliptical slots loaded circular patch antenna for wireless communications has been investigated. The proposed antenna is modified by varying the length of ground plane to increase the impedance bandwidth over the frequency range of 1 - 10 GHz. Simulated results of proposed antenna exhibits the bandwidth of 3.34 GHz (1.46 - 4.80 GHz) and 3.01 GHz (5.05 - 8.06 GHz). The proposed antenna can be used in various wireless applications, covering the Global System for Mobile (GSM) standards (DCS 1.71 - 1.88 GHz and PCS 1.85 - 1.99 GHz), UMTS (1.92 - 2.17 GHz), Bluetooth (2.41 - 2.49 GHz) of ISM band, 2.45 GHz WLAN of IEEE 802.11 b/g/n, 5.15 GHz WLAN of IEEE 802.11 a/n, WiMAX (2.5 - 2.69 GHz, 3.4 - 3.69 GHz, and 5.25 - 5.85 GHz), X-band for satellite communication (7.25 - 8.39 GHz) and point to point high speed wireless application (5.925 - 8.5 GHz) bands. Antenna is designed and fabricated on FR4 glass epoxy substrate to validate the simulated results with the measured results. Comparisons of both the results are found to be in agreement with each other. It also shows the good omnidirectional radiation pattern, appreciable gain, and acceptable radiation efficiency over the entire frequency range of 1 - 10 GHz.
Mobile Ad-hoc Networks (MANETs) are the significant technologies among various wireless communication technologies, where all the nodes are mobile and can be connected dynamically using wireless link in a random manner. The aim of in this suggested work is to avoid the attacker from forging acknowledgment packets using Enhanced Adaptive 3 Acknowledgment (EA3ACK). So, the authors have introduced a new technique of Intrusion Detection System (IDS) named EA3ACK using EAACK with Secure Hybrid Shortest Path Routing (SHSP), which is designed only for MANETs for reducing delay. Acknowledge method is implemented to rectify any type of attacks on the network with SHSP routing algorithm besides rectifying weekness results of previous work through the Network Simulator-2. Finally in this proposed scheme, a secure communication is provided with reducing overhead, delay, and packet loss using EA3ACK with SHSP algorithm increasing the efficiency of network topology.
Design and simulation of Digital Beacon Receiver has to locate the beacon signals and measure its power levels. It was designed by using Agilent Technologies, Advanced Design System (ADS) software. Some natural sources, such as full of atmosphere gases, carbon dioxide, hydrocarbon, haze, downpour, dust, mist and some other helium and nitrogen gases exists in different layers of the atmosphere, including troposphere, ionosphere can cause some obliteration on the accessibility and quality of downlink examine periods. This climate incident cause errors and difficulties, such as attenuation changes in polarization, fading delay, and dispersion. Mostly at higher band of frequencies such as Ku and Ka bands, the effects of that transmission phenomenon will not be nelegectable and they should be measured. It is a consistent and protected satellite communication. Mathematical calculations for both theoretical and experimental transmission is studied and by different frequencies. Indian Space Research Organization (ISRO) has setup two different beacon signals at 20.2 GHz and 30.5 GHz on board GSAT-14 for this explanation. There is a different method to study, accurate rain attenuation distribution and satellite wave transmission, such as radar, radiometer, signal beacon method, and satellite beacon receiver. Satellite beacon receiver is one of most important responsible and reasonably priced methods in comparison with the other methods. Digital receiver estimates the signal strength of the beacon signals at 20.2 GHz and 30.5 GHz, for both polarizations (co-polar and cross-polar amplitude measurements). This paper gives the design simulation of the receiver setup using Harmonic Balance (HB), S-Parameter, AC simulation, power budget analysis, Bandpass filter design, and Fast Fourier Transform (FFT) design simulations. The simulation results match with 98% of tested results.
India is an agricultural based developing nation. India's economical benefaction of agriculture to Gross Domestic Product (GDP) is reducing the overall economic growth. Some real-time challenges are faced by the farmers due to much less knowledge about Weather Forecast, Efficient Crop-Production, Sales and regular Market Scenario, etc. Cloud Computing is a prime factor in agriculture and the most increasing way through which data, applications, and resources for computing are provided as a kind of service to the farmer. A Cloud-based framework is developed to provide the agricultural updates through SMS (in regional language), which is more useful to farmers to get the required information. By considering Data as a Service (DaaS), expert advice for Crop, Fertilizers, Market Scenario, etc., is provided to farmers against the database queries. This system will provide an easy-to-use interface for both farmers and concerned agency, and updates with any information on the market status of various products regularly.
Today there is a lot of confusion involved in allotment of parking in Government as well as Private parking spaces. However, there is no assurance of parking in some cases when there is too much traffic and crowd. Moreover, there is a high requirement of staff in making the current infrastructure work, which in turn is a load on the management. The current system is also least dependent on technology and does not use any efficient procedure to manage and maintain the parking lots. This in turn has led to increased human intervention which also makes the management of staff difficult. Due to lack of technical expertise, the system also falls back on security. The proposed system will feature high-end technical implementations such as Detection of available spaces in a single parking loT. This is achieved using high definition cameras, powerful cloud infrastructure, and various Application Programming Interface . Also, the proposed system will use a combination of physical sensors along with a digital system architecture which will make the installation, management of the parking lot, and budget management comparatively easier than the current manual system. The proposed system uses physical sensors capable of detecting vehicular movement as well as any unusual activity without the need of heavy processing on the cloud. The authors have used cloud infrastructure only to store details of various parking spaces and to ease the current payment system and provide variety of digital payment processing options.
