DASITS: Driver Assistance System in Intelligent Transport System

The growing number of vehicles on the roads worldwide, lead to increase in the number of road traffic accidents. These are recognized as a major public safety problem. In this context, connected vehicles are considered as the key enabling technology to improve road safety and the emergence of next generation cooperative intelligent transport systems (ITS). In ITS, network services and applications (e.g., safety messages) will require an exchange of vehicle and event location information. Effective lane changing and routing in Vehicular Ad hoc Networks is a challenging task. This paper aims to propose a solution to ensure the safety of drivers while changing lanes on the highways. Efficient and faster routing protocols could play a crucial role in the applications of ITS, safeguarding both the drivers and the passengers and thus maintaining a safe on-road environment. In this paper we propose a Driver Assistance System in Intelligent Transport System based on the speed of vehicles, for effective lane changing in the dynamic mobility model. In our approach we present the lane changing based system on speed and minimum gap between the vehicles. The paper focuses towards the development of an Intelligent Transportation System that provides timely, reliable information to the drivers and the concerned authorities. The test bed is created on the techniques used in the proposed system where the analysis takes place in the On Board Embedded System designed for Vehicle Navigation. The designed system was tested on a Four Lane road at Neemrana in India. Successful simulations have been conducted along with real time network parameters to maximize the QoS (quality of service) and performance using SUMO and NS-2. The system implementation together with our findings is presented in this paper. To illustrate our approach we present some results of the simulation using NS-2.

Indoor and outdoor position identification using RFID

Radio Frequency Identification (or RFID) tags has found a wide range of applications in the modern world with a promising future. Tourism directly affects a countrys income. In this paper we have proposed a system which uses RFID tags for guidance of tourists. In the proposed system RFID tags are used to guide and to inform the tourists about the given location and surrounding. Tourists usually prefer guided tourism in order to get genuine information about the places of interest. The system presented in our paper provides the audio based tourist guidance information which a tourist prefers providing the relevant information about the spots. We have presented an algorithm which describes the deployment of the system even for densely populated RFID based geographic regions. The system collaborates with multiple readers while reading the RFID tag data. We have considered the cases where tag ID is used for sensing the environmental conditions and parameters and for identification purpose. The system has been tested with Adaptive Binary Splitting Scheme (ABS) for avoiding clash of tags and an adaptive synchronization algorithm, a novel technique for avoiding reader interference in a region. Also performance issues have been addressed related to efficiency in similar systems by exploiting redundancy.

VWS: Video surveillance on wheels using cloud in VANETs

As video gives a clear and quick understanding about any situation, it is considered to be the most reliable and recommended media for information dissemination. Real time video exchange in Vehicular Ad Hoc Networks (VANETs) can help in reducing the on road accidents and provide better road security by means of video surveillance. To execute this concept in VANET, the integrated model of VANET - Cloud Computing is the most efficient and viable solution. In this paper we propose VWS: Video Surveillance on Wheels Using Cloud in VANETs. In the proposed system, all the vehicles moving on the road serve as witnesses for various events with the help of camera equipped on board units. All the data (videos and images) of distinguished events are shared among the vehicles in a network termed as the vehicular cloud. All the data exchange that takes place in the vehicular cloud is saved in the central cloud server with the help of the roadside clouds for further surveillance and monitoring. The proposed work is supported with simulations in NS-2 and SUMO software. Implementation results of the partially designed hardware prove that the system has improved the efficiency by 75%.

COMIP: Cluster based overlay and fast handoff mobile IP system for video streaming in VANET's

Video is the most recommended media for information dissemination in VANETs (Vehicular Adhoc Networks) as it gives clear and quick understanding of information to the drivers. The real time and on-demand video helps vehicles on road in various possible ways. An improper provider not only leads to frequent interruptions of communications, but the transmission of the invalid video fragments would also result in the waster of precious bandwidth. However, VANETs high mobility characteristics and packet loss during communications blackouts difficult the deployment of video services in vehicular networks To address the issue, a novel video source decision scheme, named COMIP (Cluster based overlay and Fast Handoff Mobile IP System) based video delivery over VANETs, is proposed in this paper. The on-demand clustering approach, nodes with the same video requirement/supply and moving features are clustered to study the deploy ability of a video on demand. It has been analyzed the packet loss produced by network reconfiguration during handoffs and its influence in the video streamed quality. Using Mobile IP without and with fast handoffs we have taken the effects of mobility over the video transmission. We show that although fast handoffs techniques minimize blackouts. The simulation is done using SUMO and NS-2. We have checked the COMIP algorithm with the routing protocols AODV and GPSR protocols in changing topology and high mobility. The quality of service is studied on the basis of end-to-end delay and packet loss ratio. We also simulate the start up delay and Handoff latency by using the above scheme in efficient video streaming in VANETs.

Grid and region of interest-based localisation system in vehicular ad-hoc networks

Instantaneous localisation of the vehicles in a Vehicular Ad-Hoc Network (VANET) scenario is very crucial in order to manage the smart traffic model. Hence, the Global Positioning System (GPS) has gained popularity for the assistance of the autonomous vehicles and positioning. Cooperative Positioning (CP) is also one of the important solutions to solve the problem of location finding. Our intention is to provide the solution to the inaccurate positioning due to signal loss in GPS devices. In certain terrains, vehicles are sometimes unable to get their locations. To address this issue, we propose a novel grid/region-based on-road localisation system, where vehicles, irrespective of the availability of GPS signals, organise themselves in the network, exchange information and assist each other to calculate their position with higher precision for all the vehicles inside the network. The proposed system has been tested on a real test bed.

SmartGarbage Monitoring System

A healthy environment is imperative to a healthy and happy community. With the age old system of hiring people to regularly check and empty filled dustbins, the process has been prone to human error and neglect. Additionally, due to different frequency of usage of dustbins in different areas, routine checks which are based on time crevices is inefficient because a dustbin might get filled early and may need immediate attention or there might not be any need of a routine check for a long period of time. This makes present system resource expensive and ineffectual, as overflowing, stinking dustbins become more of a problem than a solution. In this paper we present a solution about the SmartBin is a network of dustbins which integrates the idea of IoT with Wireless Sensor Networks. Hundreds of dustbins in an area are embedded with low power and low cost smart sensors that are connected to an IoT device, which acts as a central hub/sink for all the bins. The bins transmit their geo-location and status of its contents to the central hub which relays this data to a cloud platform. The cloud platform further pushes the data to the client app in which the current location of the bins and their state (filled or not) is displayed in a map. The client app can be downloaded by the cleanliness department and data can be used to plan their routine check. Automation of garbage monitoring would optimize resources, reduce cases of neglect and is easy to adopt. The above Application is tested on Real test bed in NIIT University, Neemrana.
