Throughput prediction is one of good solutions to improve quality of mobile applications (e.g., YouTube or Netflix) for video streaming delivery services in mobile networks. This is because such applications require monitoring the network performances to control content quality, thus guarantee quality of service (QoS) and quality of experience (QoE). In this paper, we propose a history-based TCP throughput...
This article presents simulation results for a mobile ad-hoc network running Dynamic Source Routing reactive protocol under the conditions of limited availability and heightened response times of network nodes. Authors conclude that dynamic source routing stops being efficient in large networks and propose a hybrid routing protocol that includes the proactive phase and uses availability criterion...
Several wireless and mobile access technologies such as LTE, 3G, 802.11, WiMaX, etc, are omnipresent in the mobile terminal environment and offer different flows (e.g. data, voice and video). This heterogeneous environment requires the integration of different technologies in order to exploit their complementary characteristics and provide the mobile terminal with the best connectivity anywhere and...
Founded in 2005 YouTube has became the most fast growing stream service, that has a great impact on the internet traffic distribution. Thus understanding YouTube's characteristics is crucial to network providers. In this survey we are going to present the factors that impact user's satisfaction, in other meaning the impact on the Quality of experience(QoE). Furthermore we will discuss how to determine...
Recently, several studies have considered the use of mobile sink (MS) for data gathering in wireless sensor networks. As, it can enhance lifetime of the sensor network by distributing load among the sensors. In some delay-critical applications, a mobile sink is allowed to move along a predefined path. However, due to the predefined path and relatively slower speed of mobile sink, data gathering from...
This work presents two-rank (Wi-Fi and LTE) analytical model, from which we can evaluate the goodput of vehicular wireless network depending on the number of vehicles N in the access point (AP) coverage area. To evaluate the suitability of the model used, experimental data are compared with the theoretically calculated data. The results obtained allow us to evaluate the performance of each individual...
Tactical military communication networks operate in highly complex environments. The survivability and the range of these networks, especially the mobile wireless segments, are and will be a challenge for the present and future defence forces. OPAL, an autonomous system, has been previously presented where it extended the range and improved the survivability of tactical military networks using unmanned...
In recent years, the number of mobile devices is increasing rapidly. Meanwhile, the amount of malicious software is rising almost exponentially, alongside the diversity and complexity of malware. The flexibility of Software-Defined Networking (SDN) provides an opportunity to develop a malware detection model in more efficient and flexible manner. In this paper, we propose a network behavior-based...
This demo presents an end-to-end hierarchical control of a multi-domain multi-technology integrated fronthaul and backhaul network where a parent controller coordinates the operation of a wireless and optical child controllers managing real wireless and optical data plane resources. The services offered by this hierarchical control infrastructure are accessed through the offered REST-based northbound...
Centralized mobility management (CMM) is widely used in current long-term evolution (LTE) networks. The rapidly-growing number of mobile subscribers has led to the creation of a large number of signaling messages. This makes it difficult to efficiently manage mobile networks and the mobility of subscribers simultaneously. One of the problems related to CMM is a single point of failure. To solve the...
Future mobile networks are known to deploy a two-tier architecture of macrocell — femtocell [1]. In the two-tier architecture, femtocell downlink channels can cause strong co-channel interference to downlink transmission of macrocell users (MUs) which use the same frequency. The co-channel downlink interference to the MU might cause the MU's QoS degradation. To maintain the QoS of the MU's connection,...
Network Function Virtualization (NFV) is a promising solution for telecom operators and service providers to improve business agility, by enabling a fast deployment of new services, and by making it possible for them to cope with the increasing traffic volume and service demand. NFV enables virtualization of network functions that can be deployed as virtual machines on general purpose server hardware...
With the evolution towards the Fifth Generation of Mobile Communications (5G), Software-based Networks are paving the way to a radical transformation of Network Operators infrastructures. Novel technologies like Network Function Virtualisation (NFV) and Software Defined Network (SDN) are enabling new way of managing on-demand network resources. Focusing on the Mobile Core Network architecture, Service...
In recent times, mobile broadband networks are focused on bringing different capabilities to the edge of the mobile network. Mobile Edge Computing (MEC) addresses this issue by placing the compute and storage resources closer to the Radio Access Network (RAN), with an aim to reduce end-to-end latency, ensure better service delivery, and offer improved user experience. In this work, we propose SDEC...
Mobile phone not only becomes an important extended-self but also provides opportunity for researchers to record and investigate people's daily behaviors through it. The central goal of the study is to understand people's daily life routine as well as how they use cellphone to communicate and interact with others. Compared with conventional methods such as diary method or experience sampling method,...
The study uses speed context composed by temporal and spatial factors to analyze people's app usages in their daily life. Cellphone activities of forty-five students recruited from university campuses were recorded and analyzed. Recorded activities include app usages, monitor switching on/off, and geolocations, all with timestamp. The study categorized more than one thousand apps into seven categories...
Recently, mobile broadband networks are focused on bringing additional capabilities to the network edge. For instance, Mobile Edge Computing (MEC) brings storage and processing capabilities closer to the mobile user i.e., at the radio access network, in order to deploy services with minimum delay. In this paper, we propose a resource constrained cloud-enabled small cell that includes a MEC server...
In recent years, recommender systems are widely applied in e-commerce system to help users locating their interested information. However, the "all good reputation" problem brings down the accuracy of recommender systems. In addition, users' social network can benefit the recommendation especially when dealing with cold-start scenarios. In this paper, a novel trust-aware recommendation approach...
We describe a “crowd measurement” project, referred to as PoQeMoN, whose main objective is to identify Quality of Service (QoS) indicators in order to predict the Quality of Experience (QoE) for HTTP YouTube content on mobile networks. Results are based on experiments on an operational network. The second contribution of this paper is to show that the proposed indicator is easy to implement in order...
The main concept behind 5G mobile network is to expand the idea of small cell network (SCN) to create a cooperative network able to cache data in active nodes inside radio access and Core network. Caching technique is a workaround to deal with bottleneck in the Back-haul, as the capacity of the wireless links could not support the increasing demand for rich multimedia. In this perspective multiple...
