In this paper, we introduce the problem of road condition surveillance using a mobile vehicle as a concrete practical application of data collection paradigm on a direct path in energy harvesting wireless sensor networks (EH-WSNs). The application components together with its associated challenges are discussed throughout the paper. An optimization model is introduced for the network throughput maximization...
This paper introduces the concept of using IoT and Cloud based technology in car parking services in cities. A high-level view of the proposed system is outlined. Our solution makes the ancient parking system smarter by leveraging the power of IoT and embedding it with the latest innovation of electronic sensors & computers. An IoT-based intelligent car parking system is described. A number of...
In a mobile IoT system, IoT devices are located in a moving vehicle such as in a car, in a mobile robot or in an Unmanned Aerial Vehicle (UAV). An IoT Gateway aggregates data from various IoT devices located in a moving vehicle and its surroundings. This GW could also be located in the vehicle itself. We consider infrastructure as well as ad-hoc mode scenarios here. In infrastructure mode, this mobile...
The National Highway Traffic Safety Administration data show that drowsy driving causes more than 100,000 crashes a year. In order to prevent these devastating accidents, it is necessary to build a reliable driver drowsiness detection system which could alert the driver before a mishap happens. In the literature, the drowsiness of a driver can be measured by vehicle-based, behavior-based, and physiology-based...
Vehicle Communication is a research hotspot in recent years, and 3GPP has listed V2X communication into the process of standardization. V2X communication has a more stringent requirement for QoS and transmission delay, especially for the road safety messages. The unnecessary handovers between two base stations in a short interval, so-called ping-pong effect, impact on the quality of communication...
With the abundant on-board resources in smart vehicles, they have been considered major candidates for providing ubiquitous services. Processing and storage resources provided through on-board units along with a variety of sensing and communication capabilities can turn smart vehicles into potential computing engines that can be pooled to serve as powerful vehicular clouds (VCs). Computing tasks can...
Introducing an IP-based communication system into the mountain rescue domain would enable carrying out search and rescue missions in an effective way. With efficient mobility and multihoming support, a Mountain Rescue Team would be able to establish more effective and reliable Internet communication. In this paper, we present the Multihomed Mobile Network Architecture (MMNA), a comprehensive multihomed...
This paper proposes a method to analyse humanmade environments in order to identify ascending steps and stairs and recognize their parameters. The system uses adjustable 3D environment geometries for the detection of steps and estimates tread depth and width, riser height and yaw orientation from the camera to staircase. Those parameters are needed by humanoid robots to ensure a safe traversal of...
Due to exponential requests of users for accessing Internet wireless services, longer delays can incur in full filling requests. So optimizations for delay is required. One such method is using cache and storing frequently accessed pages in local cache. Consistency in cache and server data becomes a major issue. As if cache is not valid then whole optimization will be lost. Many researches have strong...
In this paper, we present a mobility cloud platform called CarCloud that has been designed to facilitate the real-world deployment of ubiquitous mobile telematic applications to promote smart transportation. CarCloud leverages the mobility, sensing and communication capacities of mobile devices, and collaborates with sensors embedded in vehicles (e.g., accessed via OBD-II) and cloud services to form...
This paper aims at using the novel concept of LTE-based Device-to-Device communications (D2D) as a new alternative for Intelligent Transportation Systems (ITS) vehicular communications in advanced 4G networks and beyond. We propose the Cellular Vehicular Network (CVN) solution as a reliable and scalable operator-assisted opportunistic architecture that supports hyper-local ITS services as 3GPP Proximity...
The advanced on-board vehicles' resources have given birth to the Vehicular Cloud (VC) concept. The VC is an emerging paradigm where individual mobile vehicles can be both cloud users and service providers, it enables vehicles that have sufficient resources to act as mobile cloud servers and rent out them to other vehicles. However, and with the high mobility of vehicles, user vehicles need to discover...
For the limitation of the architecture in traditional vehicle communication networks, a new architecture of the fusion heterogeneous network based on 3G/WiMAX is designed. In order to roam in 3G/WiMAX networks seamlessly, a fuzzy neural network access selection algorithm optimized on the basis of ant colony optimization (ACO) algorithm is put forward. The proposed algorithm takes radio signal strength,...
In this paper, we propose a mobile AP system for an express bus that moves fast and includes many people densely. By using mobile AP, many users can be considered as one group and it supports high received signal strength for each UEs. In case of conventional wireless communication, we model the system as a multiuser MISO system. By using mobile AP, the model is changed to single user MIMO system...
The purpose of the paper is to present a series of measurements of the mobile and nomadic satellite propagation channels in Ku and Ka bands, covering mainly the environments encountered by vehicles of public transportation. The first campaign “without leaves” conducted in April 2014 provided a good dataset of Ku and Ka-band attenuation caused by four different kinds of trees. Mobile Ku-band measurements...
With an increase in the number of mobile applications, the development of mobile crowdsensing systems has recently attracted a significant attention in both academic researchers and industries. In mobile crowdsensing system, the remote cloud (or back-end server) harvests all the crowdsensing data from the mobile devices, and the crowdsensing data can be uploaded immediately via 3G/4G. To reduce the...
This paper studies the closely related problems of target capturing and station keeping by an autonomous vehicle agent within the limitations of having access to the measurements of distance from the target only, where station keeping refers to moving the agent to a position having predefined distances from a network of sensory stations or other agents. These problems have been recently studied for...
Wireless network solutions based on Vehicular Ad hoc Networks (VANET) are the main path for vehicle manufacturers and urban traffic management systems to find the bests in convenience, intelligence and safety of traveling and transportation. In the other hand, recent equipped vehicles with newest computers with powerful processors and huge storages are new resources for network service providers to...
This study investigates Unmanned Aerial Vehicle (UAV) motion planning for ground attack missions involving enemy defenses. The UAV dynamics are modelled as a unicycle, linearized using dynamic extension and extended over a finite horizon as a piece-wise affine function. This is then formulated as a constrained, convex optimization problem in the form of Model Predictive Control (MPC) using closed-loop...
Mobile devices are often expected to perform computational tasks that may be beyond their processing or battery capability. Cloud computing techniques have been proposed as a means to offload a mobile device's computation to more powerful resources. In this paper, we consider the case where powerful computing resources are employed on a vehicle, thus they can be re-positioned in real time. User-carried...
