This research focuses on the identification and mitigation of malicious vehicles in cooperative tasks between automated connected vehicles. The approach aims to design estimators which employ the number and diversity of sensors that autonomous vehicles are equipped with in order to enrich the knowledge of the surrounding environment of each vehicle in the wireless communication network range. Since an event-triggered communication network is considered to increase the overall performance of the communication channels, the estimators have to be designed to take into account aperiodic and asynchronous measurements.

Mobile Ad Hoc

Mobile ad hoc network (MANET) is a dynamic wireless communication network. Because of the dynamic and infrastructureless characteristics, MANET is vulnerable in reliability. This paper presents a novel reliability analysis for MANET. The node mobility effect and the node reliability based on a real MANET platform are modeled and analyzed. An effective Monte Carlo method for reliability analysis is proposed. A detailed evaluation is performed in terms of the experiment results.

Communication network (CN) is the fundamental supporting network for communications systems, and products massive network resources in its construction and operation. Efficient organization and management of these resources is key issue to improve utilization of network resources and enhance overall performance of the CN. Based on the analysis of applying GIS on CN resources management, this paper studied key technical issues, design and implement the CN resources management system based on GIS, to improve the level of CN resources management and application.

State Of The Environment

Roundabouts provide safe and fast circulation as well as many environmental advantages, but drivers adopting unsafe behaviours while circulating through them may cause safety issues, provoking accidents. In this paper we propose a way of training an autonomous vehicle in order to behave in a human and safe way when entering a roundabout. By placing a number of cameras in our vehicle and processing their video feeds through a series of algorithms, including Machine Learning, we can build a representation of the state of the surrounding environment. Then, we use another set of Deep Learning algorithms to analyze the data and determine the safest way of circulating through a roundabout given the current state of the environment, including nearby vehicles with their estimated positions, speeds and accelerations. By watching multiple attempts of a human entering a roundabout with both safe and unsafe behaviours, our second set of algorithms can learn to mimic the human’s good attempts and act in the same way as him, which is key to a safe implementation of autonomous vehicles. This work details the series of steps that we took, from building the representation of our environment to acting according to it in order to attain safe entry into single lane roundabouts.

Wireless Communication Network

Mobility is the features of mobile communication that makes it desirable by all and varied. The whole world is now attractive in wireless communication as it provides users' ability to communicate on-the-go. IT is accomplished by transferring users from a radio network to another. This process is called handover. Handover occurs by adjusting the duration of soft handovers, the size of the areas and either by cell crossing or by deterioration in the signal quality of the current channel — the brief overview of handover, Handover in WiMAX and LTE, types of handover, handover types solutions, usually used handover parameters, some methods employed in the literature and I contemporary the convergent fact for continuance in the area of mobile wireless communication Handover.
