Abstract

Conformal antennas are required whenever an antenna has to conform geometrically to some shaped surface. In this paper a cylindrical conformal antenna array with line feed technique is implemented. At first, an inverted U- slotted non conformal circular patched antenna with a radius of 16.3 mm, thickness of 1.6 mm, and a substrate permittivity of 4.4 is designed to operate at 2.4 GHz. The simulated results are in close agreement with measured results. The measured S11 for non-conformal antenna is -17.4 dB at 2.4 GHz. The inverted U-slotted circular patch antenna is made conformal to cylindrically bent substrate of thickness 0.762 mm with a permittivity of 2.55 and it resonates at 2.63 GHz. Further, an array of three elements of conformal U-slotted circular patch antenna flush mounted on cylinder 1200 apart. From the results, it is evident that gain is increased with cylindrical conformal array antenna. The gain of proposed conformal array antenna is of 5.02 dB. Simulation is carried out using HFSS software.

Abstract

Programmable System on Chip (PSoC) devices are becoming forerunning technologies in the field of embedded systems design. The innovation of PSoC device comes from the user configurability of analog and digital array blocks. The Programmable System-On Chip devices are integrated with processors, memory and peripherals to facilitate easy and modular design in building embedded applications. This paper describes in general about the PSoC device architectures and design of a test module using the PSoC device (CY8C26443) for testing the resources like Analog to Digital and Digital to Analog Converters (ADCs and DACs) of a microprocessor based embedded system.

Abstract

The objective of E-shaped patch antenna with hexagonal slot is to operate in the ISM band for different kind of applications such as WLAN, GPS and various modern wireless systems. The posit antenna is designed using FR4 substrate having a dielectric constant of 4.4 with a thickness of 1.6mm. Probe feed technique is used for this antenna design. A parametric study was included to determine the effect of design approaches and the antenna performance. The realization of the designed antenna was analyzed in term of boost (gain), return loss and radiation pattern. The design was upsurge to confirm the best achievable result. This antenna resonates at three different frequencies at 1.6 GHz, 3.24GHz and 5.6 GHz with a reflection coefficient less than -10dB and VSWR<2.

Abstract

While planning and designing the operation of the wireless sensor network, major focus is always on balancing the energy consumption, lifetime of the node and data aggregation. This may be achieved through suitable clustering technique which helps in minimizing the distance between cluster head nodes and associated cluster members. Some of the algorithms like, LEACH, GCA (Genetic Clustering Algorithm), ERP (Evolutionary Routing Protocol), EAERP (Energy Aware Evolutionary Routing Protocol), HSA (Harmony Search Algorithm) work on similar lines. Due to variety of constraints inherently present in WSN, the objective function of clustering technique is of multi-objective nature. One of the objectives may be of minimization type whereas other may be of maximization type. Due to conflicting goals of objective functions it might be difficult to find a unique and optimal solution. This paper examines multiple solutions and compares performance of these candidate solutions for their applicability in the clustering process of WSN. Pareto optimality concept has been incorporated in the proposed work for multi-objective problem of clustering in WSN. Multiple objectives based approach with customized stopping criteria in the proposed work results in to near optimal solutions with reduced simulation time requirements and improved network performance in terms of energy usage, data delivery from the sensor nodes to the base station.

Abstract

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.

Abstract

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.
