Cognitive Routing in Software-Defined Maritime Networks

Cognitive Routing in Software-Defined Underwater Acoustic Networks

There are two different types of primary users (natural acoustic and artificial acoustic), and there is a long propagation delay for acoustic links in underwater cognitive acoustic networks (UCANs). Thus, the selection of a stable route is one of the key design factors for improving overall network stability, thereby reducing end-to-end delay. Software-defined networking (SDN) is a novel approa...

A fault tolerance routing protocol considering defined reliability and energy consumption in wireless sensor networks

In wireless sensor networks, optimal consumptionof energy and having maximum life time are important factors. In this article attempt has been made to send the data packets with particular reliability from the beginning based on AODV protocol. In this way two new fields add to the routing packets and during routing and discovering of new routes, the lowest remained energy of nodes and route tra...

Software Defined Networks

In previous chapters we have seen why SDN is necessary and what preceded the actual advent of SDN in the research and industrial communities. In this chapter we provide an overview of how SDN actually works, including discussion of the basic components of a Software Defined Networking system, their roles, and how they interact with one another. In the first part of this chapter we focus on the ...

Virtualization in Software - Defined Networks

H osted cloud computing has signif icantly lowered the barrier for creating new networked services. Likewise, experimental facilities such as the Global Environment for Network Innovations (GENI; www. geni.net) let researchers perform largescale experiments on a “slice” of shared infrastructure. By letting tenants share physical resources, virtualization is a key technology in these infrastruct...
