This paper proposes a wide pass-band filter using combination of transmission lines and square resonator structures arranged in symmetrical fashion, for numerous wide band applications. Dual-Square Complementary Split Ring Resonators with permittivity of 2.65 are identified to contribute for wider bandwidth of the filter. This novel approach enhances the coupling phenomenon and also reduces the insertion loss in the spectrum of passband. To demonstrate the advantages and practicality of this approach at the preferred band, the return and insertion losses of the filter were scrutinized. Band-pass filters play a considerable role in wireless sector. Frequency selection plays a central role in filtering. Signals have to be filtered at a specific center frequency with certain bandwidth during acquisitions. Cross dualparallel coupling at the arms provide better results in terms of frequency selectivity, rejection rates, fraction band width, and Q-factor along with low average insertion losses in comparison to other filtering techniques.
In present days, Wireless Sensor Networks (WSN) play an important role in wireless communication. Wireless Sensor Networks are self-configurable, self-healing networks consisting of a larger number of small size sensor nodes. Senor Node is composed by processor, memory, battery, sensor devices and transceiver. WSN focuses mainly on sensing environment data and transferring it to the computational centre via the sink. Mobility Models play an important role in the performance of WSN. In this paper, various performance parameters of WSN on different mobility models are analyzed with the help of NS- 3.22 simulation tool. Network performance depends on the nodes' population and displacement.
A coaxial fed tri-band model has been proposed for microwave access, which is typically involved in the applications of L and S band that combines Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access 3 (WiMax). The proposed model has a size of 20×20×1.66 mm with FR4 epoxy as a dielectric substrate, which has a relative permittivity of 4.4. It has symmetrical slots on the conducting patch which are C-shaped and also has a rectangular strip slot in ground plane, so that tri-band can be obtained. It is mainly designed to work within 1 GHz to 8 GHz. The designed structure is simulated by High Frequency Structure Simulator (HFSS) and the peak value of return loss, 27 dB, is obtained at 3.5 GHz frequency. The simulated results depicted that the proposed antenna will respond well over 2.38-2.43 GHz, 3.43-3.56 GHz and 5.5-5.8 GHz frequency band.
In today's world, the multi-core processor is very popular and has huge applications in Digital Signal Processing, Networking, Embedded System, General Purpose Computers etc. As the single-core processor has its own limitations, and complexities because of a single core, a multi-core processor attracts many researchers to work for the improvements in time and power consumption of the system, as it contains multi independent central processing units. The cache coherence is one of the major issues of the multi-core processor and cache handling is more complicated. Hence, it is important to design a method, so that the cache memory can be handled. In this paper, authors have proposed a design to utilize the cache memory in an efficient manner in the supervision of cache controller and also for reducing the power consumption.
This paper analyzes the performance of down-link communication in a multi user transmit antenna selection system (TAS) over two wave diffused power (TWDP) fading channels. In TAS system the transmitter selects the best antenna out of the total transmit antennas based on the channel state information (CSI) of the system. A closed form expression has been derived for outage probability and the average bit error rate (ABER) for different binary modulation schemes in the form of single fold integral. Also, ABER and outage probability have been studied for different channel conditions with arbitrary transmitting antennas and users.
Light Fidelity (Li-Fi) is based on “illumination” method for transmitting Data by using Light Emitting Diode’s and reception of data by photo sensor as detector. The objective here is to transmit the audio signal through Light Emitting Diode’s and recover the data using Light Dependent resistor. The Li-Fi is having high speed economical adaptation of Wi-Fi on the basis of visible light communication. Due to its better efficiency over radio base technology it has become an idea of keen interest in past few years. This technology not only increases speed of transmitting data but also increases the Capacity, Bandwidth, Security and reduces cost.This can be easily achieved by colour modulation or intensity modulation thus it can be a good solution of all radio frequency issues.
Wireless sensor networks (WSNs) have a large vary of applications as a result of they will be custom-made for a varied environment. WSNs consist of collection of sensor nodes which has limited processing power and restricted memory unit. Main task of this network is the reliable routing of packets from sensors to the base station (BS). WSNs operate severally in harsh places wherever a person’s presence is risky or perhaps not possible. Since their life time relies on their batteries and replacement and recharging these batteries is not possible in rough places, thus minimizing energy dissipation and increasing the network life period is the primary concern for the sensor networks. Nodes are basically stored in non-overlapping cluster to support scalability, energy efficiency and efficient routing. During this paper, we examine presently proposed clustering algorithms for WSNs. We are going to shortly discuss the operation of that algorithm, and also draw comparison on the performance between the various schemes. Specifically, we are going to examine the performance in term of power and quality aspect of those schemes. This paper ought to give the reader with a basis for analysis in clustering schemes for WSNs.
