Multi-constrained Quality of Service (QoS) routing algorithm is always a difficult problem in routing research area, which is a NP problem. Software Defined Network (SDN) is a new network architecture, in which there’s few research on QoS routing. This paper generates the whole network virtual topology according to the characteristics of SDN, and based on the principle of simulated annealing, p...

Software-defined networking (SDN) is an emerging network technology that decouples the control plane from the data plane. Using SDN, a fine-grained flow-level inspection for cyber security can be performed by capturing suspicious packets on the network and steering the captured traffic to a traffic analyzer. This work proposes a flow inspection scheduling for various types of traffic flows on S...

Smart environment requires uninterrupted connection when moving from one network to another. This is best accomplished at the network level (L3). Full interoperability and integration of heterogeneous networks is necessary for communication session continuity. Software Defined Networking (SDN) with virtual IP addresses solves the problem. Implementing a homogeneous SDN is expensive, given the e...

Energy efficiency in Wireless Sensor Networks (WSNs) has always been a hot issue and has been studied for many years. Sleep Scheduling (SS) mechanism is an efficient method to manage energy of each node and is capable to prolong the lifetime of the entire network. In this paper a Software-defined Network (SDN) based Sleep Scheduling algorithm SDN-ECCKN is proposed to manage the energy of the ne...

We explain the notion of security architecture for Internet of Things (IoT) based on software-defined networking (SDN). In this context, the SDN-based architecture works with or without infrastructure, that we call SDN-Domain. This work describes the operation of the proposed architecture and summarizes the opportunity to achieve network security in a more efficient and flexible with SDN. An ov...

-With the rapid development of Internet, the complexity of the network and control difficulty has increased dramatically. For the problem of fossilization network is more and more prominent, SDN (software defined network) arises at the historic moment. Due to SDN controller centralized control and the characteristics of shunt on SDN network equipment, this paper puts forward that part of nodes ...

For IP-based mobile networks, efficient mobility management is vital to provision seamless online service. IP address starvation and scalability issue constrain the wide deployment of existing mobility schemes, such as Mobile IP, Proxy Mobile IP, and their derivations. Most of the studies focus on the scenario of mobility among public networks. However, most of current networks, such as home ne...

Software-defined network (SDN) is a new programmable networking designed to perform tasks easier by enabling network administrators to add network control via a centralized control platform and open interfaces. Common network use procedures such as traffic shifts, troubleshooting and various types of device configuration. Thus devices are needed to reconfigure with the network, in order to crea...

Software Defined Networks (SDN) have been proposed for use in applications of the Internet of Things (IoT), termed as software-defined IoT (SD-IoT) network, because of the popularity and capability of mobile devices being used for networking in relatively large areas. However, a single controller in SDN has a limited request-processing capability, so a distributed control plane with multiple ph...

Software-defined networking (SDN) is an emerging architecture that offers advantages over traditional network architecture. Segment routing (SR) defines the path of information through the network via an ordered list of multi-protocol label switching (MPLS) mechanisms on the packet headers at the ingress device, and this system makes SDN routing management more simple and efficient. SR can also...
