Federating the portability and mobility of mobile devices with the computation capacity on desktop computers have been a widely discussed computation model for the next decade. However, the mobility of the mobile devices also introduces challenges on the federation. This work developed the elastic computation framework to tackle the aforementioned challenge. The elastic computation framework federates...
Smart mobile devices are already used for everyday communication between people. They have become ubiquitous devices for receiving and sharing important information, but they poses limited capability of storing and processing multimedia content. Considering that mobile devices will always have these mentioned limitations, the proposed solution is to use collaborative, adaptive multimedia content delivery...
The DA/MS/SS Track is concerned first and fore-most with emerging managerial and organizational decision-making strategies, processes, tools, technologies, services and solutions in the Digital Age. This track has 4 interrelated themes. First theme, Analytics, focuses on decision making processes, tools and technologies. Mobile services focus on development and delivery of data, information and analysis...
Crowdsourcing is an emerging paradigm where users can pay for the services they need or receive rewards for providing services. One example in wireless networking is mobile crowdsourcing, which leverages a cloud computing platform for recruiting mobile users to collect data (such as photos, videos, mobile user activities, etc) for applications in various domains, such as environmental monitoring,...
In mobile ad hoc networks (MANETs), nodes usually have limited radio power and transmit in a very limited area. Communication beyond a node's radio range requires multiple hops between nodes, which in turn, requires nodes in MANETs to cooperate with each other in forwarding packets from a source to a destination. Problems in cooperation arise in self-organizing MANETs where selfish nodes exist. Selfish...
The significant development of mobile cloud computing allows a mobile user to access resources of the nearby mobile devices, i.e., Cloudlets, for processing tasks by using the offloading mechanism. However, due to the mobility of the user and cloudlets, the connection between the user's device and cloudlets may be interrupted since cloudlets move out of transmission range of the user's device. Consequently,...
This paper proposes a performance model for mobile networks carrying adaptive streaming traffic. The proposed model takes into account the flow dynamics in addition to the main parameters influencing the performance of adaptive streaming, such as the playout buffer and the video bit rates. We show how to compute several performance metrics like the average video bit rate, the deficit rate, defined...
The aim of this paper is to give a detailed modeling and performance analysis of Small Cell wireless Networks considering the limited number of mobiles served in each cell and different vacation schemes of the base stations channels, using the Generalized Stochastic Petri nets formalism. Hence, we show how this high level formalism allows a simple construction of detailed and compact models for such...
Network functions virtualization is one of the most promising networking technology trends for mobile operators. Such functions often are considered as virtualized version of physical devices. They follow the same implementation, deployment, and operation and management model as such physical entities. However, some key characteristics of the underlying cloud technologies, such as the elastic provisioning...
Many multimedia applications over Mobile Ad hoc NETworks (MANETs) require Quality of Service (QoS) to meet real-time services. Accurate Available Bandwidth (AB) prediction and allocation of AB are important component for QoS provisioning which is affected by many factors such as latency, bandwidth, reliability, packet-loss, memory size, buffer cache, available capacity, and CPU speed. Media Access...
This paper describes the process of design and implementation of multimedia foreign language teaching simulation software is an open system, the simulation of the software system can realize multi computer courses in foreign language, practice. Course selection, foreign language selection method using menu, each foreign language simulation with animation, pictures and text forms, which uses the material...
Over past few years, among wireless technologies, MANETs has become one of the most important and effective area in extending research capabilities. A great array of scope is lying as platform for research scholars as MANETs are vulnerable to attacks because of their high volatility in location and motion. Protocols assume that no malicious intruder node is present, which impacts all the layers by...
In the era of this growing technology, Mobile Cloud Computing (MCC) has become a major discussion thread for transforming the internet computing infrastructure. For IT world, MCC provides a vast platform where mobile users can explore their data anywhere anytime using Cloud services. Mobile Cloud Computing integrates the advantage of cloud computing, internet technology and mobile computing. That...
The paper presents the use of logistic regression to compute the reliability of MANets based on AODV, DSR and DSDV routing protocols. Simulation is performed in ns-2.35 simulation software. Comparisons of reliabilities of various types of MANets are presented in the paper. The simulation result shows that the reliability of MANet based on AODV and DSR routing protocols are better than MANet based...
The existing mobile Agent model is not good at solving mobile terminals task seamless migration issues in mobile cloud computing environment, this paper proposes a mobile Agent-based task seamless migration model for mobile cloud computing. It constructs the structure of task seamless migration model based on the traditional mobile Agent and describes function of each part. Then, migration weights...
Motivated by studies of wireless ad hoc networks in obstructed environments, in this work we focus on the problem of establishing connectivity at an intersection of two roads, or streets, surrounded by obstacles. An instance of the problem is defined by four street segments meeting at an intersection point, a street width, a node density at each street segment and a transmission range of the communication...
The instrumentation of Self-Organising Network (SON) Functions in such way that they contribute to the operational objectives defined by a wireless network operator is a complex task. In order to enable automation of this configuration, we previously described the concept of a SON Objective Manager (SOM) which determines the best configuration based on conditional, ranked objectives and SON Function...
This paper studies multicast in mobile opportunistic networks. Multicast is an important routing function that supports the distribution of data in a group of users. Our approach is based on the Home-MEG (Markovian Evolving Graph) model. Two types of multicast are investigated: the regular k-ary tree and the irregular uniform recursive tree. The boundaries on the multicast time are determined for...
Mobile Internet access has become the norm rather than an exception in our daily lives, resulting in a large proportion of traffic attributed to mobile devices. To enhance the mobility support in Internet architecture, many research initiatives have devoted to investigating Named Data Networking (NDN) as the fundamental paradigm for the future Internet. NDN supports the consumer mobility by re-issuing...
Nowadays, mobile networks approach a steady growth in traffic demand. As a result, mobile network providers continuously expand their network infrastructure mainly by installing more base stations. Currently, there is a huge number of base stations serving mobile users all over the world, and this number is expected to double in the coming few years, which leads to a larger wastage of energy during...
