Abstract

Smart Grid is the integration of Electrical and Communication network in which data and power flows bi-directionally. The activity of a Smart Grid heavily depends on the instant electrical data received through the communication network. The massiveness of devices and direct communication with the end user makes the Smart Grid infrastructure easily prone to attacks. A slight modification in the data by an unauthorized person may destruct the entire grid. Characteristics like vast data generation, complexity, prompt speed and large geographical distribution area limits the existing security algorithms from being used in the communication network of the Smart Grid. In this paper, we propose an efficient security algorithm using Dual Euclidean algorithm along with its key management technique for Smart Grid application. The proposed algorithm uses two keys to encrypt the data which provides NP-hard complexity and the adversary cannot reveal the original data without knowing both the keys. The performance and security of the proposed algorithm are evaluated and compared with AES algorithm. The simulation results demonstrate that proposed algorithm is suitable for Smart Grid applications.

Abstract

In this paper, a single layer wideband, probe fed modified U-slot microstrip patch antenna is designed for four-band communication system. The proposed antenna has impedance bandwidth of 28.57%(1.2 -1.4 GHz), 14.28%(2.6-3.03 GHz), 5.12%(5.7-6.05 GHz) and 8.9%(7.5-8.2 GHz) at center frequency 1.4 GHz, 2.8 GHz, 5.85 GHz, 7.85 GHz, with gain of 4dB, 10.4dB, 6.1dB, and 10dB. High gain of 10.4dB and 10dB is achieved at center frequency 2.8GHz and 7.85GHz respectively which is applicable for radar application and satellite application. The proposed antenna is designed on a single layer substrate Arlon AD250A with defected ground plane. Antenna is designed and simulated using HFSS v13 software.

Abstract

The ultra wideband (UWB) technology plays a major portrayal now a days. The ultra wideband (UWB) technology has encountered numerous significant advancements as of late. Then again, there are still more challenges in making this technology mainstream and open to its finest use. One specific challenge is the UWB antenna with notched bands. The late apportionment of the 3.1-10.6 GHz range by the Federal communications commission (FCC) in 2002 for Ultra Wide band applications, has displayed an appealing open doors and tackles for antenna designers in the field of wireless communications. As indicated by FCC definition, the technology which possesses greater than 500MHz of data transfer capacity, or greater than 25% of the operating centre frequency, is considered as ultra wideband. In this FCC allocation of frequency band for UWB applications, there are now a few narrow band communication systems existing, which might conceivably interfere with the UWB systems. Thus there is always necessity of design and advancement of UWB antenna with band-notched characteristic. This paper demonstrates recto-circular patch antenna with band notched characteristic which is suitable for ultra wideband (UWB) applications. The antenna with height of 1.5 mm and dielectric constant is used for design. Furthermore, fairly good radiation pattern, return loss and gain of antenna are presented, which shows that proposed antenna is well suited for distinctive UWB applications.

Abstract

In co-operative spectrum sensing system, secondary users co-operate among themselves, improving the cognitive radio spectrum sensing performance. The presence of two or more malicious user in the secondary users severely degrades the performance of the cognitive radio spectrum sensing system. In this paper, the author have studied the detection and elimination of the malicious users in a co-operative spectrum sensing system using clustering technique namely k-mean clustering and compared its performance with Dixon's outlier test and box plot test. The performance of the system with different outlier tests is shown by plotting the receiver operating characteristics curves. From this we can show that cluster removal method outperforms the Dixon's outlier test and box plot test for the case of two or three malicious users in a co-operative spectrum sensing system for cognitive radio network.

Abstract

Radio Resource Management(RRM) in LTE MBMS system is the research issue addressed by this paper. LTE-advanced is in rapid process such that more and more people concentrate on system performance such as high data rates and system capacity especially with cell edge users. The proposed low complexity algorithm is designed to improve overall data rates of the system. It is proposed to reduce the computational cost. Simulation results are carried out by considering Long Term Evolution system, aiming to improve the Aggregate date rate (ADR) and system throughput with low computational cost.
