Towards video streaming in IoT Environments: Vehicular communication perspective

Multimedia oriented Internet of Things (IoT) enables pervasive and real-time communication of video, audio and image data among devices in an immediate surroundings. Todays vehicles have the capability of supporting real time multimedia acquisition. Vehicles with high illuminating infrared cameras and customized sensors can communicate with other on-road devices using dedicated short-range communication (DSRC) and 5G enabled communication technologies. Real time incidence of both urban and highway vehicular traffic environment can be captured and transmitted using vehicle-to-vehicle and vehicle-to-infrastructure communication modes. Video streaming in vehicular IoT (VSV-IoT) environments is in growing stage with several challenges that need to be addressed ranging from limited resources in IoT devices, intermittent connection in vehicular networks, heterogeneous devices, dynamism and scalability in video encoding, bandwidth underutilization in video delivery, and attaining application-precise quality of service in video streaming.

Cloud Computing in VANETs: Architecture, Taxonomy, and Challenges

ABSTRACT Cloud computing in VANETs (CC-V) has been investigated into two major themes of research including vehicular cloud computing (VCC) and vehicle using cloud (VuC). VCC is the realization of autonomous cloud among vehicles to share their abundant resources. VuC is the efficient usage of conventional cloud by on-road vehicles via a reliable Internet connection. Recently, a number of advancements have been made to address the issues and challenges in VCC and VuC. This paper qualitatively reviews CC-V with the emphasis on layered architecture, network component, taxonomy, and future challenges. Specifically, a four-layered architecture for CC-V is proposed including perception, coordination, artificial intelligence and smart application layers. Three network components of CC-V, namely, vehicle, connection, and computation are explored with their cooperative roles. A taxonomy for CC-V is presented considering major themes of research in the area including design of architecture, data dissemination, security, and applications. Related literature on each theme is critically investigated with comparative assessment of recent advances. Finally, some open research challenges are identified as future issues. The challenges are the outcome of the critical and qualitative assessment of the literature on CC-V.

Vehicular Ad-hoc Networks (VANETs) has witnessed significant attention from academia and industries, due to the growing number of applications and devices focusing on safety and efficiency in transportation. Video Streaming in Vehicular Communication (VSVC) presents interactive real-time view of an emergency incidence on roads. On-board unit of vehicles are utilized for streaming real time video of on road traffic, and disseminate among vehicles via Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication. VSVC is a challenging task due to the delay constrained nature of video data and dynamic vehicular network environment.

Geographic forwarding techniques: Limitations and future challenges in IVC

Maintaining the reliability of Next Hop selection (NHS) in Inter-Vehicle Communication (IVC) technology has witnessed significant attention among researchers nowadays. The reason is because reliable selection of the next hop could improve the performance of geographic routing protocols, which is a major goal of Intelligent Transportation Systems (ITS) applications. This paper provides a qualitative survey of recent Geographic Forwarding Techniques (GFTs) that have been proposed for the improvement of NHS along the route or on the road between two junctions.

Energy-Efficient Resource Allocation Technique Using Flower Pollination Algorithm for Cloud Datacenters

Cloud Computing is modernizing how Computing resources are created and disbursed over the Internet on a model of pay-per-use basis. The wider acceptance of Cloud Computing give rise to the formation of datacenters. Presently these datacenters consumed a lot of energy due to high demand of resources by users and inefficient resource allocation technique. Therefore, resource allocation technique that is energy-efficient are needed to minimize datacenters energy consumption. This paper proposes Energy-Efficient Flower Pollination Algorithm (EE-FPA) for optimal resource allocation of datacenter Virtual Machines (VMs) and also resource under-utilization. We presented the system framework that supports allocation of multiple VMs instances on a Physical Machine (PM) known as a server which has the potential to increase the energy efficiency as well resource utilization in Cloud datacenter. The proposed technique uses Processor, Storage and Memory as major resource component of PM to allocate a set of VMs, such that the capacity of PM will satisfy the resource requirement of all VMs operating on it. The experiment was conducted on Multi-RecCloudSim using Planet workload. The results indicate that the proposed technique energy consumption outperform the benchmarking techniques which include GAPA, and OEMACS with 91% and 94.5% energy consumption while EE-FPA is around 65%. On average 35% of energy has been saved using EE-FPA and resource utilization has been improved.

Minimizing Route Coupling Effect in Multipath Video Streaming Over Vehicular Network

Multipath video streaming is one of the most commonly used strategies for high data rate transmission. It is employed to achieve lower delay, load balancing, and path diversity. However, multipath strategy experiences the problem of route coupling due to concurrent transmission via multiple paths. This problem leads to data collision and wireless contention. Therefore, in this paper, estimation of the angle between multiple paths to minimize route coupling effect and the use of Packet Error Rate (PER) as a link quality parameter for multipath video streaming has been considered in order to achieve qualitative video delivery, by minimizing interference due to route coupling effect. Firstly, mathematical formulations of the path selection and PER parameters based on the angle of forwarding are presented. Further, the numerical formulations are implemented using Matlab. The numerical results are presented showing the probability of the presence of a vehicle in an angle area. The PER is analyzed considering both shadowing and non-shadowing settings. The results based on the PER demonstrate its impact on the angle of path selection, which in turn improve the quality of the video streaming.

Emergency data handling medium access control protocol for wireless body area network

Wireless Body Area Network (WBAN) assists in monitoring of the health conditions of a patient. The monitored data of a patient require diverse QoS and need to be delivered to the coordinator without delay and packet loss. In this context, this paper proposes a MAC Superframe structure which allocates channels based on the severities of the detected data of a patient and transmit immediately without delay and loss. The simulation results show that the proposed MAC performs better by reducing delay and improving throughput.

Energy-Efficient virtual machine allocation technique using interior search algorithm for cloud datacenter

Cloud Computing is revolutionizing how Computing power is generated and consumed over the Internet on a pay-peruse basis over the past few years. The broader acceptance of Cloud technologies has led to the establishment of datacenters. Over the years, high energy consumption by datacenters has become a major interest as a result of increasing demands of resources and services by enterprise and scientific applications. Consequently, datacenter infrastructure turns out to be not only expensive to sustain, but also unfavorable to the surrounding environment due to their huge carbon emission. Thus, energy efficient virtual machine allocation techniques are required to overcome high energy consumption due to improper resource allocation within the data centers. This paper proposes Energy-Efficient Virtual Machine allocation technique using Interior Search Algorithm (ISA) that reduces the datacenter energy consumption and resource underutilization. The results shows that, the energy consumption of GA and BFD is 90%–95% as compare to the proposed EE-IS which around 65%. On average 30% of energy has been save using EE-IS as well the utilization of the resources which has also improved.
