To improve the handover performance of network mobility basic support (NEMO-BS), several schemes have been developed. However, these schemes are designed for a single vehicle and hence may incur significant signaling overhead in the vehicular networks (VNs). Therefore, we propose an bulk fast handover scheme to mitigate such signaling overhead. Simulation results show that the proposed scheme significantly...
Mobile Opportunistic Commerce (MOC) is a new mobile commerce mode, its essence is a kind of information service mode based on location service, it saves time cost and path cost for the users by providing opportunity commerce information, and forms the opportunity benefits. By users paying for these information services, the values are delivered between the participating entities of the MOC. Based...
In this paper we intend to use vehicular ad hoc network to together and assemble real-time speed and position information on single vehicles to optimize signal control at traffic by road. First specify systematically the vehicular traffic signal control difficulty as a job scheduling difficulty on processors with job equivalent to platoons of vehicles. Then jobs are planned using an online algorithm...
This paper describes a framework for the motion coordination of networked vehicle systems. This framework is grounded on the UC Berkeley experience in the design, implementation and demonstration of control and communication systems for networked vehicles for land, sea and air applications. In this process we have developed a perspective on bringing together technological developments, theoretical...
We consider a pool of mobile vehicles with unicycle-like kinematics. During the motion and on the basis of the state variables a function defines if there is the need of coordinating the motion of a set of vehicles. When a group of mobile robots establish the need of coordination, they form a “team”. The birth of a team is an event. A sequence of intermediate targets is then assigned to each vehicle,...
Constant increase in urban road traffic is forcing traffic authorities to confront unavoidable congestion problems these days. This creates new challenges for city planners to generate traffic routes with better designs and improve the existing roads. In order to analyze and improve traffic routes, there is a need to understand movement patterns of major vehicular traffic inside the city. Origin Destination(OD)...
Electric powertrains in mobile work machines are able to increase the efficiency and the effectiveness of the work process. Conventional powertrains are operated at their limits and thus efficient electric systems are entering the applications of mobile work machines. A simple electric powertrain consists of an energy source attached to an inverter-fed electric machine. Adding a DC/DC converter to...
Timeliness is one the most important factors in emergency management. Emergency notification mechanism has to be hassle free and quick, in order to have efficient response for any disaster, health-fix, act of terrorism, etc. In this paper, we present service architecture for emergency alert, using Fog computing. Fog computing brings cloud resources close to the underlying devices and IoTs, which makes...
Tracking vehicles has many applications, especially in traffic engineering, including estimation of travel time/speed, traffic density, and Origin-Destination matrices. In this paper, we propose local alignment of mobile phone signal strength measurements to track the movement of vehicles, and demonstrate its application to travel-time estimation for a road segment. We use local alignment instead...
The ongoing convergence of cloud computing and the IoT gives rise to the proliferation of diverse, large-scale IoT and mobile cloud systems. Such novel IoT cloud systems offer numerous advantages for all involved stakeholders. However, due to scale, complexity, and inherent geographical distribution of such systems, governing new IoT cloud resources poses numerous challenges. In this paper we introduce...
Emergency situations are unfortunately part of our lives. Today's smart computing allow us handle such situations and fulfill our requirements more efficiently and effectively. This paper presents architecture to handle various kinds of emergency situations more efficiently and effectively, by allowing the user (victim or witness) easy and quick way to alert the concerned department (s) with just...
In this paper, we present an optimal monitoring and evacuation methodologies for pilgrims in Arafat area of Makkah with the aid of Wireless Sensor and Actuator Networks (WSAN). In addition to its significant impact, the proposed application has many challenges that need to be tackled. We highlight these challenges and provide a Rings overlay that efficiently contributes to monitoring the area and...
This paper primarily deals with behavior-based control strategy for an autonomous agent to achieve local goal while tracking a desired path/trajectory. The behavior-based control approach addresses multiple control frameworks, which are switched depending on the circumstances, instead of using a uniform control framework. The need to pursue local goals may arise while an autonomous agent e.g., an...
It is believed that small cells will play a very important role in future network (e.g. 5G) to meet the high user requirements in traffic volume, frequency efficiency, and energy and cost reduction. The small cell network is a new paradigm for successful deployment of m-health applications. It can enhance the medical Quality of Service (m-QoS) for the indoor and outdoor end users (e.g. patients and...
Through this work we had created a platform that will support the emergency health care procedures starting from an emergency call until a patient is transferred to a central hospital. The platform consists of a) a system that supports emergency dispatch protocols, b) data recording and workflow management of ambulance department and c) an emergency telemedicine system which can support patient handling...
Although the potential of Vehicular Ad-Hoc Networks (VANETS) to improve road safety and traffic efficiency for next-generation vehicular traffic system has been well investigated and proved, the performance of vehicle-to-vehicle (V2V) communication, especially at urban intersections has not been clearly quantified. In this paper, we evaluate the effects of buildings on the vehicle-to-vehicle performance...
This paper proposes Health Drive, a novel mobile healthcare platform with context-aware multiple-sensor integration to promote safe driving. Health Drive employs a multi-tier vehicular social network (M-VSN) architecture that consists of three tiers: network tier, mobile device tier and cloud tier. The network tier provides communication supports, and the mobile device tier works in parallel with...
Joint purchases are a growing business activity with benefits to both consumers and sellers. We present a system that proactively and intelligently helps identify opportunities for joint purchasing and carry out this type of transactions.
Mobile cloud computing is a novel computing model, which integrates the cloud computing into the mobile environment and overcomes obstacles related to the performance, environment and security discussed in mobile computing. For a mobile cloud computing application system (MCCS), reliable components substitution is an important issue for troubleshooting and system upgrading. In this paper, this issue...
Mobile environments, such as vehicular communication systems (VCSs), are typically subjected to network fluctuations and intermittent downtimes, e.g., If service consumers operate in a tunnel or switch between cells of an ISP. In this work, we present an approach for service and data prefetching from the Cloud, which allows to ensure continuous service delivery and consistent quality of experience...
