Abstract:
Abstract—There is a continuous business need for network technologies to increase in functionality, performance and com-plexity. However, the present network paradigms show a lack ofadaptability and are limited to single domain management. Thus,management of the network places a burden on the network’susers. In addition, the high number and variety of stationaryor dynamic devices make the network massive and intractable,with a complexity that leads to scalability challenges. Modernrequirements cannot be supported by the current decentralizedmobile ad hoc networks (MANETs) standard models. Addition-ally, MANETs suffer from packets/network overheads due totopology changes with the distributed and (decentralized) routingin each node. In a typical architecture, the mobile node isresponsible for dynamically detecting other nodes in the network.The node can communicate directly or via an intermediate node,and to specify a route to other nodes. Thus, the node takes adecision with only a limited view of the network’s topology. Tothis end, the deployment of the Software Defined Networking(SDN) paradigm has the potential to enable the redesign ofthese models. SDN provides a global view of network topologyand a programmable network with centralized management.In this paper, we propose a new architecture for SDN-basedMANETs, which is adding an Open Virtual Switch (OVS) pernode to find the effect of OVS on the MANETs performance. Wepresent a practical implementation for the new architecture usingexisting OpenFlow protocol. The tests have been carried out inan emulation environment based on Linux Containers (LXC V2.0.11), Open Network Operating System (ONOS V 2.5.0) as aremote controller, NS3 and Open virtual Switch (OVS V 2.5).
