Abstract

As wireless senor network (WSN) has broad range application that needs privacy of sensed data while they transmit from source to base station. Providing robust and reliable data aggregation scheme with securing sampled data is a challenging problem in WSN. This paper discusses about secure data aggregation and proposed the new secure cluster based aggregation of private data scheme using the LEACH protocol. The proposed scheme (Cb-SDA) is based on the additive property of complex number to aggregate the sensor data in order to provide the privacy during their transmission over the base station and provide better security for wireless sensor network routing with efficient performance in terms of energy consumption, throughput, delay, bandwidth utilization, jitter etc. Simulation study evaluates the performance of proposed scheme and calculates aggregation privacy, communication overhead and accuracy in terms of throughput and compare to existing approach.

Abstract

In this paper, we have achieved an compact & multiband fractal antenna using a Koch curve geometry. The simulation of the proposed antenna is done by CST Microwave Studio EM simulation software. The proposed Koch curve fractal antenna proves that it is capable to create multiband frequencies. The proposed fractal antenna is designed on FR-4 substrate with ℇr= 4.4. The antenna is fed with the probe feed method. We got two resonant frequencies like 32.84GHz & 34.28GHz which shows multiband characteristics. Simulated results shows that the return loss is better than 15 dB, the VSWR is less than 1.3, the directivity is greater than 6dBi & the gain is more than 6dB in each band. So this fractal antenna can be suitable for the radio astronomy & space research applications.

Abstract

In this paper, we have achieved an efficient rectangular patch antenna with optimized parameters by using MATLAB. The proposed antenna is a type of radio antenna with a low profile which is mounted on a flat surface. It consists of a flat rectangular sheet or patch of metal, mounted over a larger sheet of metal called a ground plane. A resonant frequency of 3 GHz is achieved with improved parameters like high return loss, Low VSWR, High directivity & gain, High efficiency. So the proposed antenna can be suitable for the radio astronomy & space research applications.
