Due to rapid topology changing and frequent disconnection makes it difficult to design an efficient routing protocol for routing data among vehicles, called V2V or vehicle to vehicle communication and vehicle to road side infrastructure, called V2I. The existing routing protocols for VANET are not efficient to meet every traffic scenarios. Thus design of an efficient routing protocol has taken significant ...

Vehicular Ad hoc Network is a special kinds of MANET (Mobile Ad-Hoc-Network), where each of the vehicle refer itself as a node and exchanging data packets themselves. When vehicles don't share acknowledgement from valid authority, reduce network connectivity, share random and false information, suddenly change speed, are unregistered or expired, those behaviors treat them as a malicious vehicles. For the purpose of road safety such kinds of malicious vehicles have to be confined and blocked its participation in the network further. In this paper, we have experimented the behavioral difference between Normal node &Malicious node in AODV routing Protocol and compared their performance based on TCP and CBR connection with varying pause time and also varying some parameters and measured performance metrics such as packet delivery ratio, loss packet ratio and average end-to-end delay.

It also requires good understanding of scene and contextual embedding for robust semantic interpretation of images for natural language image descriptor. To generate image descriptor in Bangla, we created a new Bangla dataset of images paired with target language label, named as Bangla Natural Language Image to Text (BNLIT) dataset. To deal with the image understanding, we propose a hybrid encoder-decoder model based on encoder-decoder architecture and the model is evaluated on our newly created dataset. This proposed approach achieves significance performance improvement on task of semantic retrieval of images. Our hybrid model uses the Convolutional NeuralNetwork as an encoder whereas the Bidirectional Long Short Term Memory is used for the sentence representation that decreases the computational complexities without ...

So, it is very necessary to identify the pros and cons of routing protocols which can be used for further improvement or development of any new routing protocol. This paper presents the pros and cons of VANET routing protocols for inter vehicle communication.

One can easily expect that in the twenty-first century, the use of robots will expand in our society. We believe that robots will achieve a wide assortment of undertakings in homes, war zones, atomic plants, government establishments, production line floors, and even space stations. In this paper, we are throwing some light on robotics with a robot that is utilizing the human structure to make movements like walking and dancing. This biped robot is also able to detect an object in front of it. This has been accomplished using Arduino Nano (ATmega328P), servomotors SG90 operating on the principle of servomechanism, and ultrasonic sensor to detect objects near it and prevent the robot from proceeding forward. The robot has ultimate use in entertainment, in marketing, and in assisting visually impaired to navigate.

For efficient communication between nodes various routing protocols and mobility models have been proposed based on different scenarios. Due to rapid topology changing and frequent disconnection makes it difficult to select suitable mobility model and routing protocols. Hence performance evaluation and comparison between routing protocols is required to understand any routing protocol as well as to develop a new routing protocol. In this research paper, the performance of two on-demand routing protocols AODV & DSR has been analyzed by means of packet delivery ratio, loss packet ratio & average end-to-end delay with varying speed limit and node density under TCP & CBR connection. 1.

Vehicular ad hoc network is formed by cars which are called nodes; allow them to communicate with one another without using any fixed road side unit. It has some unique characteristics which make it different from other ad hoc network as well as difficult to define any exact mobility model and routing protocols because of their high mobility and changing mobility pattern. Hence performance of routing protocols can vary with the various parameters such as speed, pause time, node density and traffic scenarios. In this research paper, the performance of two on-demand routing protocols AODV & DSR has been analyzed by means of packet delivery ratio, loss packet ratio & average end-to- end delay with varying pause time, speed time and node density under TCP & CBR connection.

With the continuous development of the Internet of Things (IoT) is becoming progressively more important for air monitoring, traffic monitoring, smart home control, smart parking management and other industrial and home applications. A real-time air monitoring system is essential for Bangladesh because of gas leak-related incidents and other types of phenomena especially for Dhaka city. In this paper, we propose a smart real time Air Monitoring System with emergency alert based on Internet of Things (IoT), which allows users to track the surrounding air quality of their home or office or industries from anywhere. An alarm goes to user of the system in case of any emergency life threatening situation.

Our research-based project is elucidating robotics with a tiny humanoid robot following the human structure to make gestures like strolling, dancing, and detecting objects near it. It has been achieved using Arduino Nano (Atmega 328P), Servo motors SG90 working on the conception of servomechanism and the Ultrasonic sensor to identify obstacles and restrain the Robot from going ahead. The aim is to fabricate a bigger humanoid robot that will serve our general public and make our life simpler. The Robot has eventual utilize in marketing, entertainment and helping the visually impaired to move from one place to another. This project can also be a great apparatus for future research works and alteration.
