Increased availability of wearable devices, smart phones establishes a platform for designing innovative distributed crowd sourcing mobile applications. These applications can take advantage of computation offloading to augment the constrained resources and unavailability of required context on single mobile device. ContextMete is an offloading architecture that execute such applications across the...
One of the thrusts of mobile and pervasive computing is supporting vision-based perception applications. Vision-based applications, such as augmented reality, are those that help users augment their understanding of the physical world through the camera(s) on their mobile devices. Such applications need to provide a seamless experience and hence require minimal end-to-end latency. However, these applications...
Mobile cloud computing (MCC) is the most promising cloud solution for the future mobile environment. It aims to integrate mobile devices with cloud computing, and provide to mobile users an online access to unlimited cloud resources. Furthermore, MCC has changed the concept of mobile devices from primitive gadget to full computers that accommodate work, personal and mobility needs. Thus, in this paper...
Mobile cloud computing is a promising approach to overcome limitations of mobile devices in terms of battery consumption and capability to execute computation-intensive applications. It consists in outsourcing some parts of computation-intensive applications to cloud servers, so that the overall energy consumption and execution time of application's running are optimized. In addition to classical...
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...
Mobile device consumerisation has introduced the Bring-Your-Own-Device (BYOD) trend to the organisational context, allowing employees to work using their personal devices. However, as personal mobile devices are perceived as less secure than those provided by the organisation, BYOD has risen security concerns about corporate information being accessed by mobile devices from inside and outside the...
The resource demands of specific services develop as well along with the increase of mobile. Nonetheless, mobile certainly will often be restricted performance that is regarding computation, storage, battery life, context adaptation of connectivity, scalability, and heterogeneity included security issue. An outstanding solution to address these limitations is definitely to offload computation is mobile...
For the last decade, researchers are showing interest in mobile cloud computing (MCC) for its promising potentiality. It combines cloud computing and mobile computing providing better quality of service to user with mobile device. Resource famished applications can now be executed on mobile devices by offloading the task on cloud. Major research areas in MCC are how, where and when to offload a task...
Existing research on implementing the mobile cloud computing paradigm is typically based on offloading demanding computation from mobile devices to cloud-based servers. A continuous, high quality connection to the cloud infrastructure is normally required, with frequent high-volume data transfer, which can have a detrimental impact on the user experience of the application or service. In this paper,...
Proliferation of Cloud markets has created influx of e-service consumers seeking cost effective services. But, mobile consumers face the challenge of intermittent internet disconnection, long latency, and high energy consumption. To address this challenge, Ad-hoc Mobile Cloud (AMC) paradigm has evolved, where web services are hosted and provided by mobile peers. However, there are three inherent challenges...
Computation offloading is a promising way to improve the performance as well as reducing the battery power consumption of a mobile application by executing some parts of the application on a remote server. Recent researches on mobile cloud computing mainly focus on the code partitioning and offloading techniques, assuming that mobile codes are offloaded to a prepared server. However, the context of...
Although extensive progress has been made in Mobile Cloud Augmentation, automated decision support on the device that enables the opportunistic and intelligent use of cloud resources is missing. Furthermore, we need solutions with reflective capabilities that can handle a changing environment and runtime variability. To simplify the deployment of smart mobile applications, we present a framework with...
The ad-hoc mobile market is the environment that allows the interconnectivity of mobile devices within community of users that are ready to communicate and share services between providers and consumers. Issues like service discovery and selection are major obstacle in ad-hoc mobile. With the growing of this market, researchers are concentrating on service discovery with little on selection. Provision...
In this paper, we propose a context-aware distributed data storage mechanism to optimize the performance of reading/writing in the emerging mobile cloud computing environment. In particular, the exploited context information including user mobility pattern, network condition, and data access preference (intensity to read and write/update). The context information is utilized to improve the efficiency...
eHealth technology can bring about many benefits for patients, health professionals, and institutions by providing faster, safer, and better healthcare services through the integration of Information and Communication Technologies (ICTs) with eHealth. We believe the success of the next generation of healthcare services requires advances in modern computing to support truly intelligent, instrumental...
We improve data access efficiency in mobile cloud storage by exploring users' context information. Specifically, we optimize data reading and writing on mobile devices from/to distributed cloud storage according to network condition, user mobility pattern, and data access preference. We propose a Reed-Solomon erasure code based context-aware distributed storage system. Then, a mixed integer linear...
As the number of mobile devices per user increases, the need to connect/combine them grows. Current approaches focus on the use of cloud-hosted backend services which allow file and app-state synchronization but fail in providing true resource sharing among mobile devices. To enable true resource/service sharing, the mobile devices of a single user should be combined into a cloud of cooperating mobile...
Over the last few years, we are witnessing the proliferation of mobile Internet devices (MIDs) and the wide spread adoption of cloud computing for both personal and corporate usages. These technologies are converging in what is known as mobile cloud computing (MCC) paradigm. This paradigm aims at addressing resource poverty of mobile devices. Several works investigated the challenges of mobile cloud...
The widespread use of mobile devices such as smartphones and tablets is flanked by an ever increasing supply of mobile applications. Along with this trend, expectations and requirements of users rise as well. For example, users do not want to compromise on comfortable daily routines as available on desktop computers. However, an intrinsic characteristic of mobile devices is their limited availability...
