Street Lights are absolutely important and without them, people would be risking their life every minute they spend on the roads. The main problem involved in street light hardware system is excessive consumption of power. This amount of power consumption can be minimized by designing smart street lighting systems in order to have smart cities. To enable the growth of smart cities and help them shape into self-sustaining, energy harvesting, green hubs, the energy must be conserved. To solve this problem there are many smart street lighting methods which discussed efficient ways to conserve power. To support the financial needs of some of the proposed methods, a struggling economy like India would not be able to afford the costs. However, to make it truly smart and affordable, the number of sensors involved in the street lighting system can be reduced strategically to account for driver’s visibility range as well as power consumed by the lights. The algorithm discussed in this paper, takes advantage of Cellular Automata [CA], to simulate the traffic similar to real-time traffic and utilized Bernoulli’s probability distribution to analyze the randomized the traffic present on the roads. This helped to visualize the situation as aptly as possible. According to the statistics street lights use up nearly 38% of the electricity produced. If this energy is saved using an energy saving scheme such as the one discussed in this paper, that energy can be utilized elsewhere – where there is an absolute and immediate need, for instance smart cities. According to the results obtained through the utilization of the method discussed in this paper, nearly 50 percent of the energy consumed by the existing smart street lighting systems can be saved. If the energy thus saved is transferred to the development of the smart cities, more than 100 of them can achieve full transition from an urban city into a smart city.

A transmultiplexer (TMUX) is a system which allow various users to share a common channel. A TMUX system capable of handling users belonging to different communication standards is called as a multi-mode TMUX. A method for implementation of such a TMUX of variable nature using fixed minimum hardware units is presented in this paper. The hardware reduction is achieved in two ways. First is by implementing variable bandwidth filters in the filter bank of TMUX using fixed filters and the other is by representing the filter coefficients in canonic signed digit (CSD) representation. The CSD representation is obtained by rounding the maximum precision coefficients to the finite precision coefficients with a limited number of signed power of two terms.

In this paper, a cooperative spectrum sensing system (CSSS) based on energy detection method and hard-decision fusion is proposed. The performance through complementary receiver operating characteristics (CROC), total error rate (TER), and throughput is analytically investigated under the influence of noise and generalized κ – μ fading. More precisely, each cognitive radio (CR) senses the PU through erroneous sensing (S) channels and reports the sensing information in the form of binary-decision obtained using energy detector (ED) to fusion center (FC) through erroneous reporting (R) channels. Next, the hard-decision is performed at FC to obtain a global decision on the status (active or inactive) of the PU. Towards that, we derive a novel-analytic expression of detection probability subject to noise and κ – μ fading is derived. The analytical frame works based on derived expression for evaluating TER and throughput performance for any network and channel conditions are developed. Further, the CSSS performance for differen network parameters such as channel error probability, time bandwidth product, signal to noise ratio (SNR), number of CRs, detection threshold under various fusion rules is investigated. Finally, an optimal detection threshold, an optimal number of CRs, and maximum throughput for several network parameters subject fusion rule are also determined.

Mobile Ad hoc Networks (MANETs) envisioned as battlefield application of wireless networks build cooperation in a multi-hop fashion between limited powered mobile nodes to prove inter-communication with one another. In self-configuring and self-organizing nature MANETs, designing adaptive protocols is a great challenge. Remarkably flexible natured bio-inspired algorithms and new design approach of cross layer interactions meet the needs of adaptability in MANET’s protocols. The adaptable protocol’s performance depends on accuracy of calculation and acquisition of network conditions. This paper proposes ant based technique to estimate the network conditions. Cross layer interactions enable optimization in end- to-end delay using network conditions like node density and traffic intensity parameters. Simulation study shows that adaptive management of protocols in MANETs has improved performance even at high data transmission rates, and for larger number of nodes.

In-network data compression is achieved in a wireless sensor network using Block Truncation Coding technique. This provides data compression and the consequent energy saving. In Block Truncation Coding, binarization and fixing of quantization levels are the two major steps. By shifting the binarization pre-processing to the sensor nodes, in-network compression is realized.

The phenomenon of open-source software (OSS) has gained importance among the information technology (IT) firms and software entrepreneurial ventures in the recent years due to its advantages over proprietary closed software including high level of innovation, low cost of development, availability of reusable architectural and functional component, free and unrestrictive access to the source codes. The firms have started recognizing the importance and value of the open source software over the proprietary closed software. It is important to understand and analyze various characteristics of the OSS projects which influence their performance. In this research, we examine OSS project characteristics forks count, number of contributors, project age, project size, project owner, number of programming languages used, primary language intensity, and watchers using 130 project repositories which are started in 2017 from GitHub one of the leading web-based Git version control repository hosting services. A conceptual model of OSS Project performance and hypotheses are developed. The results conclude that the number of programming languages, the project size, the number of contributors, and the project age are showing significant positive influence on the OSS project performance. The project ownership and the primary language are not showing any significant influence on the OSS project performance.

The unmanned aerial vehicles or drones are gaining popularity because of increased demand for less human intervention in the automotive sector. Customer driven markets are encouraging the unmanned vehicles oriented industries toinnovate towards the average user level. Despite the improvements in the parameters like cost, user friendliness and technological capabilities people hesitate to work with the unmanned vehicle technology and the major reason for this would be the vehicles behavior in the known and unknown environments, the unavoidable obstacles on the path of travel or the doubt on risk factor associated with the collision avoidance system. So this paper presents the various techniques used in the smooth navigation and collision/obstacle avoidance system over past years.

In recent days, Field Programmable Gate Array (FPGA), provides the ability to integrate multiple tasks through the parallel operations. This processor is preferred over DSP for the implementation of controller to control speed of induction motor through power converter employed in industrial applications. This paper presents the implementation of FPGA based closed loop V/F speed control of induction motor. The existing approaches having the limitations of regulating slip and conversion of frequency in proportion to the slip. This issue can be addressed by summing the slip with actual speed during conversion of speed into frequency. Further, this paper focuses on the development of the PI controller using Xilinx block sets to improve the tracking ability of the controller. The developed controller is validated on hardware test bench consisting of FPGA based controller connected to Induction motor drive. Finally, it can be concluded that FPGA processor provides a real deterministic behavior of induction motor employed in industrial applications

Most of the new generation mobile phones are equipped with smart and unique features that provide a great experience in music, internet, capturing videos and many more applications. But the same experience is not achieved in voice communication when the surrounding environment is too noisy. Hence development of algorithms for processing complex voice is very much essential for speedy and correct estimation of speech signals. This skill, demand processing of voice signal digitally for feature extraction and remove the undesired noise sources. In this paper, the degraded signal is pre processed before passing through Mel-filter bank further Mel frequency Cepstral coefficients are found and feature extraction is carried out. Since the voice signals tend to have variation in temporal rate, adaptive equalization is used for feature matching techniques. The test pattern in this paper presents an improvement in speech index by a factor of 20-30%.
