Performance Analysis of RPL Routing Protocol for WBANs
Full text linkThis research article focuses on evaluating the performance of RPL protocol for WBANs. The WBANs place stringent requirements for the protocol design due to its adhoc nature, heterogeneous data rate, requirement of mobility and ultra-low power consumption. Many works have been focused on evaluating the RPL protocol through simulation; on the other hand the real world implementation has its own vulnerabilities. So it is important that the protocol should be experimented on the real hardware devices. This work aims in developing an inter-WBAN to monitor the vital health parameters such as heart beat and body moisture level of two or more patients simultaneously. It has been proved that the RPL performance is far superior to simple multi hop technique by comparing various performance attributes
Analysis and Modeling of Physical Stratum for Power Line Communication
Full text linkIn recent days, power line communication is one of the emerging technologies for high data rates (data transmitted at high speed). It is also cost effective and dependable channel. It is used in many applications such as home automation, broadband internet access, car embedded systems etc. Orthogonal Frequency Division Multiplexing dependent PLC physical layer is presented in this work. It is measured in terms of BER employing MATLAB 2013a. Here, multipath channel model is employed for the purpose of simulation because of the unavailability of a primary PLC channel
Performance Analysis and Resource Allocation in MIMO-OFDM Systems
Full text linkThe paper deals with the analysis of the vital performance plot of SNR and BER in MIMO systems. The importance of the diversity orders and the variation of the SNR-BER plot with respect to it is also studied using the simulation outputs. The three types of fading channels are also analysed. It is also seen that the presence of diversity and other schemes like Maximal Ratio Combining, selection combining, alamouti scheme increases the overall efficiency. The importance of the optimisation techniques and the superiority of the Monte Carlo optimization to the theoretical system without optimisation is also clearly visualised. The paper also deals with resource allocation in MIMO-OFDM systems. The advantage of the constant envelope OFDM over OFDM is achieved. Also the power allocation using water-filling algorithm and bandwidth-power product minimisation is compared using the obtained results
Do Brands and Branding Really Affect Consumer Behaviour?
Full text linkBrands and branding have long been considered central to marketing strategy, shaping how consumers perceive, evaluate, and choose products. This paper examines the extent to which brands and branding influence consumer behaviour in both global and Indian contexts. Drawing upon established consumer behaviour theories and brand equity models, the study explores the psychological, cultural, and economic mechanisms through which branding impacts decision-making. Global case studies illustrate how strong brands command loyalty, premium pricing, and advocacy, while Indian market examples demonstrate the evolving relationship between branding and consumer expectations in a rapidly digitising economy. The analysis also considers limitations, such as price sensitivity and brand fatigue, before projecting future trends driven by technology, sustainability, and personalised marketing. Findings suggest that branding significantly affects consumer behaviour, but its influence is contingent upon trust, relevance, and the brand’s ability to adapt to changing socio-economic realities
Automatic Vehicle Over speed Controlling System using Microcontroller Unit and ARCAD
Full text linkThe main purpose of this paper is to develop a system that avoid accidents because of vehicles with high speed. Also, authorizes the pedestrians and public to cross the highway road with no risk from vehicles which are moving with high speed. Generally, drivers of the vehicles with high speed drives in an uncontrollable manner even in speed limited areas without taking into consideration about the public. Even traffic policemen could not able to control them and attain good response from the high speed vehicle drivers. Also, we cannot monitor them to limit their speed at all times in those areas. So, here we develop a system which controls the speed of the vehicles in those locations without involving the drivers. Here, we employ RF communication method in controlling the speed of the vehicles. Finally, we connect RF receiver to the vehicle and locations are connected with the transmitter. Also, the transmitters are coded to send the transmitted signals continuously with a small delay between the adjacent signals. So, if a high speed vehicle is entering the location then their receivers will automatically senses the received code. Thereafter, the speed of the vehicle is limited dynamically by employing an embedded system inside them
The Lowest Total Irregularity of a Completely Segregated ?-Bicyclic Graph
Full text linkA simple linked graph with exactly the same number of edges as vertices plus one is called a bicyclic graph. A completely segregated bicyclic network is one in which any two neighboring vertices have different degrees. Total Irregularity of a graph is defined as: irrt(G)= . In this paper, total irregularity of totally segregated - bicyclic graph is discussed and some properties of totally segregated - bicyclic graph G with =4 and n4(G)=1 is found. The basic bicycle denoted by (p,q,1) is obtained from two vertex-disjoint cycles Cp and Cq by identifying one vertex of Cp and one vertex of Cq
Analysis of “SystemC” design flow for FPGA implementation
Full text linkHigh level language termed as SystemC language is recently gaining popularity in VLSI industries especially in Hardware-Software co-design. Using SystemC, Hardware IPs can be modeled at system level which helps to reduce the time to market for SOCs. In most applications SystemC is utilized to verify functionality of the design. However there has been relatively less work done on the synthesis of equivalent hardware from SystemC. In this paper, Finite Impulse Response Filter and Greatest Common divisor are designed as examples in SystemC language and their corresponding synthesis flow from SystemC to FPGA is proposed. The proposed method of synthesis would be time saving than the conventional design and synthesis using HDL in RTL perspective
Status of Women Entrepreneurship: Motivational and Challenging Factors in Nepal
Full text linkThe main objective of this paper is to explore the motivational and constraining factors that effects the women entrepreneurial growth in Nepal. The result of the clearly depicts that political instability and weak implementation of law and order in Nepal has been a major stumbling blocks for women entrepreneurial growth besides giving greater attention to the creation of conducive culture for women empowerment. Thus, the study draw conclusion that there is still a substantial room for women entrepreneurial growth in Nepal because their current role in business is far from satisfactory
Design and analysis of Low Power High Speed Pulse Triggered Flip Flop
Full text linkThe main important aspect is to outline a high speed and utilization of low power pulse triggered flip-flop and simulate the same. Also, we have to minimize leakage in the consumption of power in a flip-flop by employing pulse triggering technique that is adopted for clocks. Here, to solve the problem in the discharging path of the similar flip flop implementations, we employ signal feed through technique. The discharge time is reduced by the proposed method. This design out performs all the other similar pulse triggered flip flop implementation both in speed and power consumption. Now, it is implemented by employing Cadence Virtuoso Schematic Composer in 90nm GPDK. Simulation is done by a simulator known as Spectre
Prevention of Emulation Attack in Cognitive Radio Networks Using Integrated Authentication
Full text linkSecurity is the prominent problem in emerging cognitive radio. Protecting the chief user’s and sub-ordinate user’s right to use the spectrum results in the correct cognitive radio operation. The major user emulation attack is a physical layer attack which disrupts the secondary user’s operation. An Advanced Encryption Standard scheme is used in this work that aims to defeat the chief User Emulation Attack by the correct detection of the chief user. The reference signal is encrypted and transmitted along with the Digital TV signal. Using a shared secret the receiver regenerates the reference and the cross association and the auto correlation are calculated which helps in the accurate detection of the chief user as well as the malicious user. The simulations were carried out and the results show that the detection scheme results in zero misdetection and also false alarm which is below a set threshold
