“…On the other hand, perceived delay and jitter in our experiments have remained low (<25 ms). These results are in line with other studies on IEEE 802.11ac, which prove that a high data rate is compatible with a low mean delay and mean jitter [98]. In addition, these features are not critical for this kind of application where the response time in accessing the server (cloudlet or cloud) does not affect the outcomes achieved.…”

New information and communication technologies have contributed to the development of the smart city concept. On a physical level, this paradigm is characterized by deploying a substantial number of different devices that can sense their surroundings and generate a large amount of data. The most typical case is image and video acquisition sensors. Recently, these types of sensors are found in abundance in urban spaces and are responsible for producing a large volume of multimedia data. The advanced computer vision methods for this type of multimedia information means that many aspects can be dynamically monitored, which can help implement value-added applications in the city. However, obtaining more elaborate semantic information from these data poses significant challenges related to a large amount of data generated and the processing capabilities required. This paper aims to address these issues by using a combination of cloud computing technologies and mobile computing techniques to design a three-layer distributed architecture for intensive urban computing. The approach consists of distributing the processing tasks among a city's multimedia acquisition devices, a middle computing layer, known as a cloudlet, and a cloud-computing infrastructure. As a result, each part of the architecture can now focus on a small number of tasks for which they are specially designed, and data transmission communication needs are significantly reduced. To this end, the cloud server can hold and centralize the multimedia analysis of the processed results from the lower layers. Finally, a case study on smart lighting is described to illustrate the benefits of using the proposed model in smart city environments.

The wireless mesh network (WMN) is a future network technology that develops single-hop wireless local area networks (WLANs) into multi-hop wireless mesh networks, based on the IEEE 802.11s standard. However, this development still presents many challenges, such as determining the best route between sources and destinations, especially taking into account the use of the medium access control (MAC) and physical (PHY) layers of IEEE 802.11n/ac. Some papers have proposed rate adaptation algorithms particularly for single-hop networks; however, these only focused on mechanisms to find data rates suitable for channel conditions. In IEEE 802.11s WMNs, the design of the rate adaptation algorithm is more challenging. Besides considering the problem of channel quality and optimal throughput, it is necessary to also consider the problem of collision and the best route. It is important to take collision into account because the collision probability in multi-hop mesh networks is higher than that in single-hop networks and can lead to a lower throughput. Rate adaptation algorithms for IEEE 802.11s WMNs have been proposed in other papers, but they also do not consider the use of the MAC and PHY layers of IEEE 802.11n/ac. In this paper, we propose the collision-aware rate adaptation for optimal high-throughput (CARA-OHT) algorithm for WMN IEEE 802.11s. An evaluation through the extensive use of a network NS-3 simulator shows that the proposed algorithm exhibits a higher throughput than previously developed algorithms.

“…These wireless networks as extension to a wired backbone network going to be around in the future as more and more devices being released with wireless support [5,20]. However, a wireless network suffers problems related to limited bandwidth than a wired network which is why a wired backbone network is preferred over a wireless backbone [1,12].…”

Gigabit Ethernet (GbE) backbone network with wireless extension is gaining much popularity in campus, small businesses, and corporate network environments worldwide. A good understanding on the impact of wireless extension to a wired backbone network is required for proper design and deployment of such systems. In this paper we investigate the effect of wireless extension (i.e. increasing wireless nodes) on the performance of a GbE backbone network by extensive simulation. We develop a simulation model (using OPNET simulation tool) to study the system performance with and without wireless extension under FTP, VoIP and Video Conferencing traffics for various network scenarios. Results show that FTP download response time and Video packet delays increased about 61% and 94%, respectively as a result of a wireless extension to the GbE backbone network. The findings reported in this paper provide some insights into the design and deployment of GbE-Wireless networks that may help network planners and engineers to contribute further towards developing next generation wireless networks.
