“…The forwarding rules are updated whenever there are new links formed by different interfaces. Since the involved links are wireless, it is necessary to rewrite the MAC addresses on each link, to match the source and destination MAC addresses from the associated STA/AP on the respective links [51,52].…”

Future mobile data traffic predictions expect a significant increase in user data traffic, requiring new forms of mobile network infrastructures. Fifth generation (5G) communication standards propose the densification of small cell access base stations (BSs) in order to provide multigigabit and low latency connectivity. This densification requires a high capacity backhaul network. Using optical links to connect all the small cells is economically not feasible for large scale radio access networks where multiple BSs are deployed. A wireless backhaul formed by a mesh of millimeter-wave (mmWave) links is an attractive mobile backhaul solution, as flexible wireless (multihop) paths can be formed to interconnect all the access BSs. Moreover, a wireless backhaul allows the dynamic reconfiguration of the backhaul topology to match varying traffic demands or adaptively power on/off small cells for green backhaul operation. However, conducting and precisely controlling reconfiguration experiments over real mmWave multihop networks is a challenging task. In this paper, we develop a Software-Defined Networking (SDN) based approach to enable such a dynamic backhaul reconfiguration and use real-world mmWave equipment to setup a SDN-enabled mmWave testbed to conduct various reconfiguration experiments. In our approach, the SDN control plane is not only responsible for configuring the forwarding plane but also for the link configuration, antenna alignment, and adaptive mesh node power on/off operations. We implement the SDN-based reconfiguration operations in a testbed with four nodes, each equipped with multiple mmWave interfaces that can be mechanically steered to connect to different neighbors. We evaluate the impact of various reconfiguration operations on existing user traffic using a set of extensive testbed measurements. Moreover, we measure the impact of the channel assignment on existing traffic, showing that a setup with an optimal channel assignment between the mesh links can result in a 44% throughput increase, when compared to a suboptimal configuration.

“…One of the first deployments of OpenFlow in wireless networks was at the Stanford campus network [10] where OpenFlow was deployed at WIFI-Acess points (AP) and WiMax base stations. In [12], a practical implementation of an SDN (Software Defined Networking) MANET testbed was provided. This work designs a testbed that has the advantages of device-to-device data communication and simplicity of network configuration using a centralized controller.…”

Mobile wireless Ad hoc NETwork (MANET) is a decentralized wireless network in which mobile wireless nodes either directly communicate with each other or communicate via other wireless nodes in the network. In addition, OpenFlow has disruptive potential in designing a flexible programmable network which can foster innovation, reduce complexity and deliver right economics. In recent years, there are significant interests from research communities to deploy OpenFlow in MANETs. This paper proposes a configuration method with which OpenFlow can be deployed automatically in a MANET without any manual configuration. The proposed configuration method is tested in an emulated MANET created on the Fed4FIRE testbed using Mininet-WiFi (an emulator for wireless software-defined wireless networks). Experimentation includes automatic configuration of OpenFlow in linear, sparse, and dense mobile ad hoc networks. Results show the effectiveness of the method in configuring OpenFlow in wireless mobile ad hoc networks.

“…Due to the flexibility of the wireless technologies, Ubiquitous Networks can be utilized in territories with insignificant communication infrastructure. Their autonomous nature and their ability to be operating independently providing device-todevice (D2D) communication [5] without relying to any preexisting infrastructure classifies them as an effective solution for addressing the requirements of emergency communication, since they can easily be deployed for Public Protection and Disaster Relief scenarios (PPDR) [6], [7], [8] happening in hostile and hazardous environments.…”

A selective multipath routing protocol for ubiquitous networks

During the past years, ubiquitous networks have become an interesting topic for research due to their flexible and independent nature in terms of network infrastructure. A lot of effort has been made around the design of efficient routing protocols, mainly because of their unique characteristics, such as, dynamic topology, high mobility and limited bandwidth. In this paper, we propose a new routing protocol which is based on our Multipath-ChaMeLeon (M-CML) routing protocol. We perform a network optimization analysis of M-CML under a series of simulations taking into account three Quality of Service (QoS) metrics and we provide the results with statistical confidence interval by applying the Wilcoxon signed-rank test model. On top of the outcome of the analysis, we also apply an intelligent algorithm to enhance our protocol's effectiveness by reducing the improvident emission of data packets. The new protocol, named M-CMLv2, is compared to OLSR, AOMDV and M-CML using the NS-3 simulator. The acquired results indicate that M-CMLv2 reduces the redundant information, maintains good performance at successfully delivering packets with acceptable end-to-end delay, while at the same time, it reduces the network's routing load and the energy consumption of the nodes.
