This paper focus on the use of unmanned aerial vehicle teams for performing cooperative perception using Data Distribution Service (DDS) Network. We develop a DDS framework to manage the incoming and out bounding network traffic of multiple types of data that is exchanged inside the UAV network. Experimental results both in laboratory and in actual flight are presented to help characterize the proposed...
ROV operations are expensive and there is an urge to improve on their efficiency and speed. The EU project “Effective Dexterous ROV Operations in Presence of Communications Latencies (DexROV)” proposes a solution to those needs by developing a set of hardware and software tools to support the teleoperation of ROVs over a satellite link, i.e., from remote locations including off-shore sites. A core...
Ultra-reliable and low latency communications is envisioned to enable new services and applications with high reliability, availability and low latency, e.g, factory automation, Tactile Internet. Device-to-device communication is one such mean that allows devices to experience benefits in terms of shorter communication latency. Currently most device-to-device communication in frequency-division duplex...
The standard and real-time communication technology is an unalloyed inevitability for the development of Internet of Things (IoT) applications. However, the selection of a standard and effective messaging protocol is a challenging and daunting task for any organisation because it depends on the nature of the IoT system and its messaging requirements. Copious messaging protocols have been developed...
In this work, we model route updates as part of Quality of Service (QoS) Virtual Network Function (VNF) in Software-Defined Networking (SDN) architecture. In SDN, the control plane and the data plane are decoupled. This allows high flexibility by providing abstractions for network management applications and being directly programmable. However, reconfiguration and updates of a network are sometimes...
The ability to provide a high Quality of Service is a crucial aspect in the acceptance and widespread dispersion of the Industrial Internet of Things and it has a key role to enhance the end user experience. The emerging fog cloud computing architectural concept aims to diminish the experienced latency while simultaneously providing a seemingly unlimited quantity of computational power by moving computations...
Internet of Things (IoT) has become a favored wireless communication concept in many application domains recently. Most of the IoT networks must fulfill the strict quality of service (QoS) requirements such as low latency and high reliability. Besides, low power consumption is essential in those networks due to the use of battery operated devices. Time Slotted Channel Hopping (TSCH), an operating...
In distributed Smart Farming applications, a reliable communication is often crucial, in particular during collaborating operations. In rural areas, the network connectivity via Public Land Mobile Networks is, however, not always sufficient. Network disruptions may occur hindering reliable transmissions. For the delivery of periodic sensor data streams of agricultural machines, several modern communication...
Our objective in this paper is to improve the communications performance for IoT applications by proposing a new solution called IC-IoT (Improving Communication for IoT). The principle used is the exploitation of three existing communication protocol by incorporating some mechanisms to consider the different parameters which can cause the data loses. A probabilistic approach is used to know the impact...
A key success factor for a smart grid lies on reliable data exchange between components across domains in the grid. However, a smart grid involves various types of devices and equipment having different quality concerns and computing capability, which requires a flexible communication platform that can accommodate heterogeneous devices. The Data Distribution Service (DDS) is a standard for data-centric...
Communication system design becomes more complicated due to excessive increase of number of users. Systems need to address this load, while providing acceptable levels of Quality of Service (QoS). Additionally, user expectations, quantified via Quality of Experience (QoE), need to be addressed. QoE is calculated on the application layer, where end users interact with the system. As well as user expectations,...
In this paper, we elaborate an SDN orchestration solution aiming at the dynamic adaptation of service chain paths thereby addressing high-availability requirements of 5G applications. We present an SDN orchestrator that periodically monitors the availability of the network and, if necessary, promptly adapts service chain paths to recover from congestion events and to preserve network QoS performance...
For P2P systems, one of the key challenges is to motivate peers to contribute to the system by sharing authentic files. Since the peers differ from each other in the quantity and quality of services they provide for the system, service differentiation is necessary for the sake of fairness. In this paper, a multidimensional contribution-based service differentiation mechanism is proposed. We first...
This paper briefly introduce a method to evaluate the reliability of a cloud rendering system by using probability models. An extended discrete-time Markov chain (DTMC) is proposed considering the QoS (Quality of Service). Then, some properties defined from 3 aspects give full consideration to the processes of rendering tasks, which can be verified by performing PRISM in a quantitative way. Finally,...
The promise of SDN/NFV to offer enhanced functionalities to the service provider networks is now tangible as both technologies have started being steadily investigated and experimentally demonstrated. However, a number of research challenges have not been fully addressed yet. More specifically, a limited interest has been devoted on how to assure reliability and QoS performance while data traverse...
Adopting new technologies in smart grid (SG) enables the improvement of reliable communication. A key factor for SG efficiency is reliable data exchange between different components and domains in the system. SG must allow remote and quick reaction for different events. This is not a trivial task especially with large scale power grids, which requires SG to have a reliable communication protocol....
Multiservice delivery is an important research issue in wireless sensor networks (WSNs) integrated with cloud computing, especially for heterogeneous applications which require reliable, timely and fair data delivery in adversarial environments. Therefore, both reliability requirements and delay constraints should be taken into account. Moreover, the delivery protocol should be designed to cater for...
In service oriented architecture, workflow discovery and web service composition (WSC) are two major challenges and many works have been carried out in the recent years. In this work, we address the problem of WSC in a multi-cloud environment. All existing methods assume that a feasible solution exists and solves the WSC problem, however when user constraints are hard, a feasible solution might not...
Service identification meets with new challenges with overwhelming rise of categories and numbers of services in big data scenarios. Most of the current service identification approaches have paid little attention to the granularity of indicator for service identification, neither do they provide with any trustworthy monitoring mechanism during the process of service identification. To address the...
Recent advances in wireless communication and electronic manufacture have allowed the creation of a variety of bio-sensors to be used for Wireless Body Area Networks (WBANs).
