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...
This paper considers the efficacy of using active network technology to offload computation from small mobile devices into network node computing centers. The performance of six algorithms for use in this process is compared and conclusions are drawn.
Current generation of smartphones is running more and more complex applications that reduce the battery life to as short as several hours. Thus, it becomes very important to understand the diversities of applications installed on smartphones and how batteries are consumed across different applications. This paper presents a large-scale battery study on smartphones focusing on diversities in applications...
Nowadays, with the fast advancement of mobile technology, mobile devices are more energy hungry. Battery life has become the performance bottleneck of mobile devices. Short battery life greatly reduces user satisfaction. This paper proposes GScheduler – a dynamic energy-aware task scheduler for mobile devices. The goal of GScheduler is to turn mobile devices and computers at home/office into an energy-aware...
To provide cellular communications for a large number of internet of things (IoT) devices, the mobile core system, called as evolved packet core (EPC) in the 4G system case, emerges to equip a large amount of computational resources. This is because the EPC needs to maintain state information on the communications of the IoT devices, even if they rarely send data. This paper proposes a method for...
In Today's world Mobile devices are the important handheld devices spreading throughout the world, and it is necessary to integrate web services into the mobile device. We introduce a simple approach for dynamically invoking web service methods from mobile devices with minimal user intervention that only involves entering a search phrase and values for the method parameters. This energy efficient...
Smart Internet Devices (SIDs) particularly Smartphones are soon turned to be super computers, while the restricted battery timing is a focused issue which hinders the steady meeting expectations yield of these devices. In addition, various sensors, high resolution LCDs, wireless interfaces, GPS and other advanced features drain battery quickly, thus, shrinking the operational time. Subsequently, increasing...
We present an approach for dynamically outsourcing and composing security functions for mobile devices, according to the network behavior of their running applications. Applications are characterized from a network point of view using data mining and clustering techniques with the aim to select their appropriate security functions. Software-defined networking mechanisms are employed to chain the selected...
Data Prefetching is the process of retrieving and caching data before the user has requested it. It is a technique proposed to reduce latency to data and ensure data access in case of disconnection. It can speed up the user's experience with his mobile app.
The insufficiency of battery lifetime has become the biggest limited of mobile smart-terminal, offloading of mobile computing is a potential effective method to extend the battery lifetime of mobile smart-terminal by executing some computation of applications in remote servers. However, the delay of transmission and the wireless transmission conditions are the main constraints of mobile offloading...
User equipments (UEs) such as smartphones and tablets are widely used in heterogeneous wireless networks which include different technologies like WiFi and Long Term Evolution (LTE) systems. Implementing traffic steering effectively for user equipments to maximize their quality of service has become a key challenge these years. Therefore, in this paper, we propose a device controlled mechanism. We...
The need for increased performance of mobile device directly conflicts with the desire for longer battery life. Offloading computation to resourceful servers is an effective method to reduce energy consumption and enhance performance for mobile applications. Android provides mechanisms for creating mobile applications but lacks a native scheduling system for determining where code should be executed...
Mobile devices have become for many the preferred way of interacting with the Internet, social media and the enterprise. However, mobile devices still do not have the computing power or battery life that will allow them to perform effectively over long periods of time or for executing applications that require extensive communication or computation, or low latency. Cyber-foraging is a technique enabling...
While mobile devices (such as smartphones, tablets and laptops) allow for more flexible and convenient business operations, they are susceptible of thefts. Surprisingly, mobile devices commonly go stolen at offices. When a mobile device is in the theft's hands, it can compromise the data on the device itself or even the data on corporate servers and networks, which can be accessed using that device...
As smartphones have become increasingly pervasive, large amount of mobile data traffic has started to overwhelm the networks. Surprisingly, according to [1], the main cause of network congestion in cellular networks today is not only the data traffic generated by smartphones, but also the underlying signaling from the smartphone applications such as push email, instant messaging, and social network...
Many mobile applications retrieve content from remote servers via user generated queries. Processing these queries is often needed before the desired content can be identified. Processing the request on the mobile devices can quickly sap the limited battery resources. Conversely, processing user queries at remote servers can have slow response times due communication latency incurred during transmission...
Cross platform mobile applications for a range of services including both customer and the operator related services are of considerable importance. The Smartphone user community is growing rapidly which is the evidence of a large scale use of mobile services. The social networking and online entertainment applications are introduced to the mobile community on a very rapid basis in this age. This...
The paper explores the dramatic changes that are imposed on Mobile Networks Business Models, due to introduction of All-IP Network technology. It looks at existing value chains from an architectural viewpoint and how they are affected due to the All-IP transformation. It analyses the value chain for the various parties in this ecosystem (operators, network equipment vendors, Appstores and OTT1 providers).
This paper proposes a new mobile monitoring system for environmental awareness toward wireless sensor networks (WSNs). This system assists Android OS mobile users to observe an environmental behavior, and then to alert for a sudden change with configured thresholds. The paper describes the instrument and component of the key design of the system. In addition, a new efficient technique to transmit...
A novel experimental approach for investigating the performances of context-aware content delivery schemes is presented in this paper. An innovative testbed, capable of remotely controlling multiple terminals, injecting a wide range of traffic loads in real networks and monitoring different performance measures has been developed and utilized for quantifying both the energy costs and user perceived...
