In certain platforms, such as Google Docs, documents are adapted for specific mobile device types, and the installation of their applications is required. Although the documents can be accessed via Web browsers, their correctness is not guaranteed. In content selection, the document is adapted into various versions, from which the optimal one, based on a quality of experience (QoE) criterion, is delivered...
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...
Congestion in today's mobile networks is mainly managed by end to end congestion control algorithms such as TCP. However, in spite of its many merits, TCP does not cope well with the high variability inherent to radio links and customer experience may sometimes be poor as TCP reveals unable to rapidly grasp such a fluctuating bandwidth. To remedy this problem, we introduce in this paper a new proposal...
This paper targets empirical voice and video quality assessment in mobile networks and presents fundamental QoS testing methods in correlation to RF indicators. The paper focuses on the most critical performance parameters for real-time services (e.g. voice) such as call drop vs. poor coverage in UMTS. The empirical study was based on a clearly defined drive test scenario with predetermined routes...
To gain competitive advantage in today's mobile market, cellular network testing, monitoring and improving customer experience is crucial. Today independent benchmarking companies are hired by mobile operators to run drive tests in a certain geographical areas. The high cost for running these tests results in a low frequency of execution, typically this benchmarking is executed no more than two or...
The mobile network operators (MNOs) that are deploying the IP Multimedia Subsystem (IMS) experience rapid growth of mobile contents and mobile subscribers' requests. Consequently, system performance could be affected and the management of different types of content resources gets expensive and gradually harder. In fact, with the emergence of the big data technology, MNOs must think of making the most...
The incremental needs of the wireless technologies came from the rapid proliferation of the mobile devices, which become one of the life necessities for people. The clear growth in the mobile application markets either in video, audio, or web surfing and with all the innovations and inventions in the technologies, the needs of using the wireless heterogenous networks become a fact. In this paper,...
A Mobile Adhoc Network (MANET) is featured by multi hop wireless connectivity with topology change due to highly mobile stations with autonomous configuration ability. Therefore, it is very challenging to develop vibrant and resourceful routing Protocol for MANET which also performs excellent routig with security feasibility. This paper presents a detailed study and analysis of various routing issues...
Cloud Radio Access Network (Cloud RAN) is novel mobile network architecture. It uses cloud computing capabilities to enhance the quality of service (QoS) in next generation 5G networks. The basic concept of Cloud RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Remote Radio Heads (RRHs), and move them to the cloud for centralized signal processing...
In this paper we propose architecture of software-defined heterogenous network based on integration of such modern technologies as NFV, SDR and SDN. We have discovered that mobile network that is built according to SDN, SDR and NFV principles will allow to create new mobile networks. Such networks will constitute a base for transition between standards (GSM-UMTS-LTE-LTE Advanced), providing high quality...
Transportable nodes in a healthy and demanding network set-up of Mobile Adhoc Network (MANET) are self-governing with self-configurable potential due to high occurrence of topology alteration and changeable rescheduling of the network mechanism during data communication. Due to simplicity of set up, the energetic networking system in MANET is very victorious in conditions where it is complicated to...
In this contribution, a cognitive quality of service (QoS) mechanism is proposed for improved handoff decisions in mobile communication networks. The proposed design is a hybrid channel perception tool that trains observed key performance indicators (or channel characteristics) to discover the system's channel behavior. A Hidden Markov Model (HMM) framework is adopted to ensure that the available...
With enormous growth of wireless communication technologies, mobile phone plays an important role in future development of ubiquitous network. New cellular devices are equipped with powerful computing, communicating and storage facilities which will improve scalability, energy efficiency and decrease packet delay, etc. The performance metrics like coverage, enhanced target tracking and superior channel...
Security is the main issue of the mobile ad-hoc network, because of mobile nodes behavior. The topology of MANET changes frequently due to nodes mobility, by this property newly node easily enters or exit from a particular area. In this paper, we go through the study about mobile ad-hoc network and role of soft computing in this network. In our proposed work we apply Dempster Shafer theory for calculating...
Universal telecommunications growth is largely attributed to rapid technological innovation and progressively more liberal policy environments. In the past decade, many developing countries have implemented technical and legislative reforms that have resulted in increased adoption of telecommunications technology. This has in turn led to productivity improvements and the successful adoption of mobile...
Rapid advancement in ad hoc networks and its variants, create a need for efficient and accurate routing decisions. As routing decisions for Mobile Ad hoc Networks has great impact on the overall performance of the network Quality of Service (QoS) parameters (delay, bandwidth, PDR etc.), optimized routing protocols need to be designed. One of the biggest challenges in designing ad hoc routing protocols...
Cloud Radio Access Network (C-RAN) is a novel mobile network architecture that brings baseband processing units (BBUs) of a set of base stations into a central server keeping only remote radio heads (RRHs) at the cell sites. Because of their limited resources, running sophisticated applications on mobile handsets could result in poor performances and shortened battery lifetime. One promising solution...
A Mobile Adhoc Network (MANET) is self-possessed combination of mobile nodes. It has to be self-structured. The MANET has few specific goals. These are mobility extensions into wireless domain and autonomous mobile dominion. In this set of specified nodes that form adhoc network with routing infrastructure too. Multicasting is responsible for transferring information efficiently from a source to any...
The self-organizing wireless Mobile Ad-hoc Networks are characterized by the routing protocols they employ and the wireless technology used by the nodes in those networks. Process of route formation in MANETs is based only on the decision of network layer; resulting in network prone to congestion and degraded performance. Constraints imposed by MAC sub-layer and PHY layer go unnoticed with conventional...
Quality of Service (QoS) is defined as the capability of network elements (e.g. application, host and router) to provide some sort of assurance and service differentiation for consistent network data delivery. Recently, Internet Engineering Task Force (IETF) has introduced Network Mobility Basic Support (NEMO BS) protocol (RFC 3963) to address the challenges of the entire network mobility (such as...
