The paper investigates the principles of functioning of wireless communication networks of the next generation with M2M traffic. In the early stages, the new technology will be implemented on the basis of 4G (LTE) infrastructure, complemented by innovative radio access developments and new resource management techniques for the IoT services implementation. We present the analysis of the requirements...
In this work we describe the process of deploying virtual routers in accordance with flexible time allocation of virtual access to the processor. We developed the model of software router with a set of modern mechanisms and algorithms service information flows. Using the model of the router we enhanced functionality of the device: added mode of deployment of virtual nodes with the possibility of flexible...
In this paper we propose a mathematical model of the functioning of network device with virtual routers. This model allows to decrease the mutual influence of the parametric effects of different types of traffic in the network node, as well as to estimate the quality of service by decomposition of a structure of network node and mathematical modeling based on queueing theory. To verify the proposed...
In this paper, we propose the model of adaptive routing of heterogeneous traffic with respect to the current requirements regarding quality of service provisioning. The main idea is to develop the model for effective routing with high degree of flexibility that is achieved using a set of weighting coefficients which all together constitute the general routing metric. Based on this metric the routing...
The model of the virtual router with static and dynamic reconfiguration of resources is developed. This model allows to create effective virtual device with optimal parameters (length of queue, management discipline for queue overflowing, the number of service devices and their modes) in order to provide the required level of QoS for all services. The use of virtual network devices in the existing...
This paper depicts the modern state and directions of the future development in the area of information and telecommunication systems. We analyze the most interesting and promised technologies of the last decade to define the predictable directions of further ICT shifting.
In this paper the concept of network monitoring implemented in SDN architectures are explored. This new programmable network architecture ensures a significant advantage over other because it is introduce new functionalities and easier to tune up to provide guaranteed quality of services from end-to-end for each priority flow. Monitoring the network is the first step towards a SDN forwarding protocol...
This article is dedicated to exploring new management algorithms required for heterogeneous mobile networks, taking advantage of their coverage superposition and management integration of different technology, enabling operators the opportunity to reduce installation and operational costs while offering high quality services to end subscribers. Modified analytical models are proposed to evaluate heterogeneous...
This paper is devoted to increasing the efficiency of utilization of wavelengths in optical fibers in modern DWDM systems. Today's optical network architectures are very complex and consist of several layers. While the basis of all architectures is an optical DWDM layer, the implementation of the upper layer technologies can significantly vary what makes integration of the layers very challenging...
In this paper we investigate the impact of the algorithm of intellectual vertical handover proposed by our team earlier. In this paper we have improved the algorithm of handover functioning using fuzzy logic based on cloud computing platform and core network for 5g services. To ensure the ABC (Always best connected) demands, intellectual vertical handover decision strategies have been proposed in...
In this paper the method of prioritized queue processing MPQ (modified priority-based queuing) is investigated. This method allows fulfilling QoS requirements for packets of real-time flows that have sustained some particular degree of the delay en-route. In order to test this method, the test bed that consists of virtual routers and traffic generators has been developed. Running experiments on this...
The important requirement for multiservice network is ensuring QoS indexes which significantly differ for each type of traffic. Since multimedia traffic is characterized with high burstiness and cyclic oscillation of time trend, a problem of network overload appears. Its solution requires new traffic engineering methods based on both statistical and prognosticated data. In this article algorithms...
Mobile Cloud Computing (MCC) is an integration of cloud computing in the mobile environment, which is used to improve the overall performance of the mobile devices. The rapid growth of cloud computing and mobile Internet services has triggered the emergence of mobile cloud services. Among many challenges, QoS management is one of the crucial issues for mobile cloud services. Here the survey of the...
