Monitoring and tracking dangerous goods can represent a great improvement in security and safety when transporting hazardous goods by water road. In this paper we propose a complete monitoring and tracking system, which is able to check at the same time the position and real-time status of dangerous goods of the ship, as well as the conditions in the cargo bay. The system exploits battery-powered environmental sensors (temperature, humidity, pressure, gas concentration and liquid level), connected by a ZigBee-based Wireless Sensor Network, This approach guarantees flexibility, ease of deployment and low power consumption. Collected data is then sent from the ship to a fixed server via a GPRS link. The GPS positioning system is integrated by the use of Navigation System, which also guarantees a precise estimate of the position when the GPS signal is weak or temporarily lost. When dangerous goods of the ship start leaking, the system can develop a plan to solve the accident, according to the situation at that time. The proposed solution has been deployed in a real environment, and some performance evaluation tests have been carried out.

Research And Design

Specific to the problems of current loader weighing device, for example, lack of accuracy and poor real-time processing ability, this paper designed a new type loader electronic scale and introduced μC/OS-II operating system into this system. Besides, GPRS communication module is added and the digital sensor is installed. At the same time, CAN bus is applied to carry out information transmission, which effectively improves the accuracy, real-time processing ability and anti-interference ability of loader electronic scales.

In this technological world, smartphones can be considered as one of the most far-reaching inventions. It plays a vital role in connecting people socially. The number of mobile users using an Android based smartphone has increased rapidly since last few years resulting in organizations, cyber cell departments, government authorities feeling the need to monitor the activities on certain targeted devices in order to maintain proper functionality of their respective jobs. Also with the advent of smartphones, Android became one of the most popular and widely used Operating System. Its highlighting features are that it is user friendly, smartly designed, flexible, highly customizable and supports latest technologies like IoT. One of the features that makes it exclusive is that it is based on Linux and is Open Source for all the developers. This is the reason why our project Mackdroid is an Android based application that collects data from the remote device, stores it and displays on a PHP based web page. It is primarily a monitoring service that analyzes the contents and distributes it in various categories like Call Logs, Chats, Key logs, etc. Our project aims at developing an Android application that can be used to track, monitor, store and grab data from the device and store it on a server which can be accessed by the handler of the application.

Tasks Scheduling

Wireless Sensor Networks (WSNs) are a growing research area as a large of number portable devices are being developed. This fact makes operating systems (OS) useful to homogenize the development of these devices, to reduce design times, and to provide tools for developing complex applications. This work presents an operating system scheduler for resource-constraint wireless devices, which adapts the tasks scheduling in changing environments. The proposed adaptive scheduler allows dynamically delaying the execution of low priority tasks while maintaining real-time capabilities on high priority ones. Therefore, the scheduler is useful in nodes with rechargeable batteries, as it reduces its energy consumption when battery level is low, by delaying the least critical tasks. The adaptive scheduler has been implemented and tested in real nodes, and the results show that the nodes lifetime could be increased up to 70% in some scenarios at the expense of increasing latency of low priority tasks.
