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...
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...
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...
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...
This study aims to design a web technology based Emergency System (SmartER) system, which will enable the doctors and nurses to perform the patient related procedures more quickly and smoothly in the emergency departments. SmartER is not just software, it is planned as a system that includes a monitor screen to be mounted on the wall, a barcode bracelet for the patients, mobile devices to be used...
In the 5G era, radio IP capacity is expected to reach 20 Gbit/s per sector, and ultra-large content traffic will travel across the faster wireless/wireline access network and packet core network. Also massive and mission-critical IoT is the main differentiator of 5G services. These types of real-time and large-bandwidth consuming services require radio latency of less than 1ms, and end-to-end latency...
We propose a privacy preserving mobile advertising system for in-app ad placement, that enables user profiling and targeted ads without revealing user interests to the mobile advertising companies. Our proposal relies on device-based user profiles, derived from app activity, on the use of Private Information Retrieval (PIR) to query ads database(s) for matching (to profile) ads, without the database(s)...
Vehicle-to-vehicle (V2V) communication technology based on Wi-Fi technology has recently been used to prevent vehicles from colliding with each other. However, in V2V communications, radio waves cannot be diffracted well enough at intersections at which vehicles cannot detect each other. Therefore, such technology might not prevent traffic accidents from occurring. In this study, we used mobile networks...
In this paper, the Beidou satellite navigation system based on the establishment of Beidou Positioning base station, select the cloud platform RTK forwarding mode, using ARM9 processor as the main controller, through the PID to adjust the output control signal, sending CAN communication instructions to control the hydraulic system to complete the intelligent agricultural machinery automatic control,...
Increased Caching Capability is one of the main benefits of Information-Centric Networking and a necessity for highly mobile ad-hoc networks such as VANETs. Hence, it is crucial to efficiently store items to improve resource utilization, increasing cache efficiency, reducing network load. In this paper, we propose a cache content insertion policy, UG-Cache, for ICN-VANETs. In UG-Cache, cache insertion...
MPEG has recently proposed Server and Network Assisted Dynamic Adaptive Streaming over HTTP (SAND-DASH) for video streaming over the Internet. In contrast to the purely client-based video streaming in which each client makes its own decision to adjust its bitrate, SAND-DASH enables a group of simultaneous clients to select their bitrates in a coordinated fashion in order to improve resource utilization...
Mobile edge caching will represent a 5G service able to improve the quality of experience of users served on mobile networks. Video streaming is the candidate traffic category which will leverage such service. In turn, the availability of rate-adaptive video playout mechanisms on board of mobile terminals will improve the video-streaming experience and offer a novel dimension to optimize caching policies...
This paper identifies that the anycast communication pattern is needed in the Machine Type Communications (MTC), where there could be multiple MTC devices being deployed in the same area for the same type of data, the client only cares about the data being retrieved but not where the data comes from. Currently the MTC server can provide such anycast service, but with large signaling overhead and bandwidth...
In this paper we explore the problem of providing selective read/write access to the outsourced data for clients using mobile devices in an environment that supports users from multiple domains and where attributes are generated by multiple authorities. We consider Ciphertext-Policy Attribute-based Encryption (CP-ABE) scheme as it can provide access control on the encrypted outsourced data. One limitation...
A smart campus refers to a campus where modern information and communication technologies bring more convenience to campus life, assist campus users to improve and more efficiently accomplish their daily activities, and enhance social interactions. Regarding the high demand of services such as mining campus users' semantic information, building augmented reality assisted mobile campus and smart class,...
The purpose of this paper is to present a smart interactive mirror interface. In this paper, we describe the design and development of a futuristic mirror that offers simplified and customisable services to the home environment. On a par with the recent advances in the Internet of Things standards and applications, the mirror is designed to enable residents to control the household smart appliances...
The continuous evolution of mobile networks is demanding and promising. The increase in mobile population, the introduction of new applications and use cases which represents a major shift in the paradigm from voice to data especially with the adoption of the IP network from the internet in the mobile networks. This has imposed challenges in current architecture of mobile networks in terms of backhaul...
Computer network and security courses are essential parts of college computer science curriculum, and hands-on networking experience is well recognized as an effective approach to help students better understand the concepts of network and security. However, existing networking labs are usually server-based and relatively cumbersome, which require a certain level of specialty and resource to set up...
Mobile Cloud Computing (MCC) leverages resourceful data centers that are distant (aka the cloud) or closely located (aka edge servers) for computational offloading to overcome resource limitations of modern mobile systems like smartphones or IoT devices. Many research works investigate context-aware offloading decision algorithms aiming to find the best offloading system at runtime. However, all approaches...
Most of latency-sensitive mobile applications require computational resources provided through a cloud computing service. The problem of relying on cloud computing is that, sometimes, the physical locations of cloud servers are distant from mobile users and the communication latency is long. As a result, the concept of distributed cloud service, called mobile edge computing (MEC), is being introduced...
