Now a days we see many train accidents that occur in railways. These accidents occur mainly due to cracks in the track, human errors and not identifying the opposite train at the right time. When the train meets with the accident lot of people lose their lives and huge amount of railway property is destroyed and it also takes lot of time to hold back to the normal situations. Most of the accidents happen due to human error and due to lack of communication between the trains and irregularity of Train Traffic Control System. Normally to prevent these accidents we place sensors on either side of the platform to identify the train at right time and to receive traffic signals at the platform properly. Here we came with some different approach which is easy to manage and implement and cost effective. Normally collision occurs when two trains approaching in opposite directions on same track. So, if we manage to prevent two trains travel on the same track then collision can be avoided. Here in this project we have implemented Verilog code to solve this problem. The purpose of this project is to write a Verilog code to detect the opposite train and deviate the train based on priority of the trains thus avoiding collision. In this project we have chosen four different types of trains namely Goods, Passenger, Superfast, Express and we have implemented train collision avoidance using Verilog code by giving priority to each type of train and preference is given to one train to avoid collision.

Internet of things involves monitoring as one of its major applications. It mostly includes condition-based decisions without human intervention. Monitoring systems continuously read the data from sensors, upload the data to a database and take appropriate decisions when they encounter an abnormal data. This provides a good basis for the IoT control systems which now are mostly common. This paper explains the solution to replace the single server system which means a centralized system with an individual server system which is a decentralized system. A decentralized system provides high security to the data and ensures data privacy which centralized systems fail to do. This decentralized system involves maintaining own server but ensuring the availability of data & communication without loss of privacy, ensuring minimization of security threats. This application involves building of a collective application on an android platform to present the data to the users based on the user hierarchy defined. The app provides high security through authentication based on the rights that user possesses. This app is designed to continuously monitor the air pollution in the areas across the city and give alerts or notifications whenever the pollution level reaches to a threshold. Additionally, the app monitors temperature and humidity level. Analytics are performed on the data from sensors and a graph is plotted as the value of a parameter across time. Separate graphs are plotted for each parameter. A user with administrator privilege can view the data of all the areas whereas a user from a single location or a user with general privilege gets the data of his own location.
