“…This framework named OpenQoS causes video traffic flows optimally in the network and is received by destination with more quality. The controller created two paths between source and destination: one for common traffic (based on OSPF algorithm) and another for multimedia traffic (based on CSP model [23] and Optimization [24][25][26][27][28]). Simulation results showed that for both actual scenario and simulation one using this model decreased PSNR parameter of receiving video in the destination.…”

Nowadays operators are forced to struggle with low level configurations and exclusives of network devices vendors to establish and maintain a secure connection and implement complex management policies on these devices. Software Defined Networks (SDN) are a new style of computer networks which provides new facilities and methods for network management and configuration by separating control level and data level. In order to improve the video Quality of Service (QoS) and increase the efficiency of the end-to-end performance, it is necessary to select the best route and implement QoS for videos, whilst there may be different routes between the transmitter and the receiver and due to network's complexity, discover the optimal route would be impossible. Hence the existing solution is a SDN with an overall view. In this paper, At First, QoS definitions are expressed. Second, traffic engineering methods in current networks is discussed. Finally, a new technique to improve QoS over SDN is proposed. Results of performance evaluation showed that the proposed method is better than existing methods.

ABSTRACT:Â The wide address space provided by Internet Protocol version 6 (IPv6) lets any thing to be identified uniquely. consistency of the modified version of IPv6 protocol stack with smart objects, facilitated the Internet interconnection of the networks of smart objects and introduced Internet of things. A smart object is a small micro-electronic device that consists of a communication device, a small microprocessor and a sensor or an actuator. A network made of such devices is called low-power and lossy network. RPL routing protocol that is consistent to IPv6, is designed to be used in these kinds of networks. Load balancing is not considered in the RPL design process. Whenever RPL is used in large scale low-power and lossy networks some nodes will suffer from congestion and this problem severely degrades network performance. In this paper, we consider solutions provided to tackle RPL load balancing problems. Load balancing algorithms and protoclos are evaluated through simulation. We evaluate IETF RPL implementation and LB-RPL method with Contiki OS Java (COOJA) simulator. They are assessed comprehensively through metrics such as Packet delivery Ratio, Average End to End delay, and Gateway Throughput. LB-RPL improves RPL in terms of Packet delivery Ratio and throughput but increases Average End to End delay. Simulations results show that RPL load balancing needs extensive works to be performed yet.

“…This method does not meet the challenges of the Lyapunov function method including determining the appropriate Lyapunov function and coefficients. The method of Volterra-Lyapunov stable matrices [21], is modified using two Lemmas and reducing the dimensions of the matrices to overcome the problems exhibited by the standard technique (presented in [21]), while in some parts of the original method this technique is not used [22][23][24]. This approach transfers the analysis from differentiable functions to related matrices.…”

This paper studies the global stability analysis of a mathematical model on Babesiosis transmission dynamics on bovines and ticks populations as proposed by Dang et al. First, the global stability analysis of disease-free equilibrium (DFE) is presented. Furthermore, using the properties of Volterra–Lyapunov matrices, we show that it is possible to prove the global stability of the endemic equilibrium. The property of symmetry in the structure of Volterra–Lyapunov matrices plays an important role in achieving this goal. Furthermore, numerical simulations are used to verify the result presented.
