The next generation of mobile network communication systems will require from Internet Service Providers (ISP) the deployment of innovative and sophisticated Quality of Service (QoS) strategies to improve users perceived Quality of Experience (QoE). ...

The state of a meeting room (or of a classroom) provides important context to the level of interest (or participation level) in a meeting. For example, in one uninteresting meeting only one presenter presents text-filled slides, while other attendees ...

VANET network is a new technology on which future intelligent transport systems are based; its purpose is to develop the vehicular environment and make it more comfortable. In addition, it provides more safety for drivers and cars on the road. Therefore,...

This paper explores the potential benefits and pitfalls of Multipath TCP (MPTCP) in smartphones via an extensive experimental study over real Android applications. We consider different types of applications - upload vs. download intensive, network ...

Unstable channel links in Vehicular Ad hoc Net- works (VANETs) make the design of reliable broadcast schemes challenging. Existing solutions fail to balance the requirements in Packet Delivery Ratio (PDR), latency and communication overhead, rendering ...

This paper discusses two issues with multi-channel multi-radio Wireless Mesh Networks (WMN): gateway placement and gateway selection. To address these issues, a method will be proposed that places gateways at strategic locations to avoid congestion and ...

With the large increases in video content, mobile network operators (MNOs) are persistently seeking to lower their content access latency and backhaul traffic. To mitigate these challenges, operators have started developing an operator-owned content ...

During the last years WLAN (IEEE 802.11) has become the primary wireless access technology. However, the fast evolution of peak data rates and the wide deployment of WLAN hotspots results in the backhaul connecting such small cells becoming a ...

Every day large numbers of users connect to IEEE 802.11 networks in order to access the Internet and all sorts of services. However, due to their unplanned and unregulated nature, and the lack of admission control and Quality of Service Guarantees, ...

This paper presents setup and results of a long-term outdoor range experiment carried out in a real environment. The objective was to explore long-range wireless communication in sub-GHz license-free radio bands, i.e., 169, 433, and 868 MHz under more ...

IMS (IP Multimedia Subsystem) is an emerging architectural framework that delivers a number of multimedia services -- ranging from voice/video over LTE, interactive gaming and many more -- in operational LTE network. Network operators are embracing ...

Software-Defined Networking (SDN) is a network architecture that aims at providing high flexibility through the decoupling of the network logic from the forwarding functions. The ease of programmability makes SDN a great platform implementation of ...

The Software-Defined Wireless Network (SDWN) has been considered as a feasible solution in order to make a fast deployment of new solutions and services; however, there is a performance degradation problem when SDWN is designed with the current IP ...

We present a topology discovery service for software-defined wireless multi-hop networks, which is capable of capturing rich information about the network topology, such as link quality, interference and node characteristics etc., to effectively support ...

Localization and synchronization are fundamental services in Wireless Sensor Networks (WSNs). Many WSN applications often need to know the sensor position and the global time to report a given event detection with a specific location and time. However, ...

Wireless sensor networks (WSNs) are one of the most rapidly developing information technologies and promise to have a variety of applications in Next Generation Networks (NGNs) including the IoT. In this paper, the focus will be on developing new ...

Because of the visual nature (images and videos) of the captured data, the coverage problem in Wireless Multimedia Sensor Networks (WMSNs) is totally different from traditional scalar sensor networks and can be defined in several ways according to the ...

The paper presents a formal approach to model, analyze, and verify a variant of Message Queue Telemetry Transport protocol (MQtt), dedicated to communicating vehicles (MQtt-CV) that send collected data to automotive infrastructures(subscribers). Our ...

Applications for intelligent transportation system provide mechanisms and tools geared to the aid and management of a city's transportation system. These applications are focused on driver safety, as well as on the management and control of the flow of ...

This paper presents the 2-hops Geographical Anycast Routing (2hGAR) protocol to enable anycast communication between vehicles and infrastructure. 2hGAR forwards packets to reach any member of the infrastructure by using information of the best neighbors ...

A beacon in Vehicular Ad Hoc Network (VANET) is a periodic message that contains status information of a vehicle such as id, velocity, location and other information that is needed by routing protocols and safety as well as non-safety applications. ...
