Computation offloading has received much attention to improve the performance or energy efficiency of mobile systems that have usually limited and constrained resource capacities. Yet, applying the computation offloading technique in opportunistic networks that are highly dynamic and often become volatile still remains a challenge due to the following reasons: (1) technical difficulties in constructing...
The ever-increasing demand for multimedia contents has imposed severe traffic overload pressure on mobile network operators (MNOs). Cooperative data offloading is a promising approach to alleviate the traffic congestion, which leverages the device-to-device (D2D) communications among mobile users. However, mobile users may not be obligated to participate in cooperative data offloading, since it will...
An emerging usage is to rely on mobile devices (Smartphones or tablets) for large-scale events. They can be used for many applications like live voting or chatting, but also to access all the data related to an event. However, in such case, handling mobile devices trying to access data simultaneously is difficult. A Wi-Fi access point can only handle a limited amount of devices. Current solutions,...
Machine Type Communications (MTC) has been paid much attention as a new communication paradigm to increase mobile network traffic. Most of MTC terminals are time-driven, that is, they send and receive data periodically. Therefore, network access requests on mobile core networks are concentrated at a specific timing, which results in instantaneous increase in network load. Considering the fact that...
In this paper, we propose a policy-based, real-time packet analytics framework developed to evaluate 3G and 4G mobile communication technologies, and the associated signaling, tunneling, & user application protocols with the ultimate goal of providing context-enriched correlated information to streaming analytics platforms based on business needs. The framework allows user-defined dimensioning,...
By taking into consideration network features of a wireless mesh network environment where mobile cloud computing (MCC) system is deployed, this paper proposes an effective virtual machine (VM) placement algorithm. This algorithm tends to place a newly created VM for a cloud service to a cloud server, which itself is also a mobile device, that occurs lowest network delay when accessing to application...
With the rapid development of wireless network, online reading has become available in mobile reading devices. E-reader users can read and buy books through wireless network. Users can not only access to real-time comprehensive resource, but also access to book reviews, book recommendations etc. 3G communicating technology significantly improved data transfer speed which can meet network transmission...
The future wireless mobile devices considered in this paper incorporate three key features: (1) Wireless Wide Area Network (WWAN) radios, (2) short-range high-data-rate Wireless Personal Area Network (WPAN) radios, and (3) large (>;100GB) amounts of on-board cache. Approaches for finding and exploiting knowledge of Social Networks to decrease spectrum congestion and network latency in networks...
The experience is everything, and we have never had so much experience to try. Mobile internet experience has become one of the new experiences in life. Firstly, this article describes the use intention of mobile Internet in China which both quantity of Chinese mobile internet users and using frequency are low. Secondly, based on TAM and flow experience theory this article builds a model of the mobile...
Mobile commerce is a new technology that offers significant adoption benefits, allowing consumers to make Internet transactions over wireless networks anytime anywhere. This paper presents some initial findings from a study into the uptake of mobile commerce services. Attitudes, subjective norms and perceived behavioural control were positively correlated with the intention to adopt mobile commerce...
The rapid spread of wireless mobile devices and the advances of wireless communication have fueled the interest about streaming 3D graphics on mobile devices to be used in augmented reality based classes of applications. In these types of applications, a real world is mapped into the virtual world and thin mobile devices are employed to navigate in the virtual simulated environment (VE). In evidence,...
Over the last few decades, the Internet has grown exponentially, bringing about hard questions about its future sustainability. At the same time, the proliferation of wireless and mobile devices with Internet connectivity has created a new landscape for a wireless future Internet. It is evident that in the emerging “Future Internet” (FI), wireless and mobile networking will remain significantly important,...
WLAN location determination algorithms can be classified into client-based approach and infrastructure-based approach. This paper proposes an infrastructure-based indoor location determination algorithm using access points (APs) as received signal strength (RSS) data collectors. Beside the role of RSS data collector, the APs can simultaneously play the role of communication. In the proposed system,...
Location aware computing is popularized and use of location information has become important due to huge application of mobile computing devices and local area wireless networks. To serve us well, mobile computing applications need to know the physical location of things so that they can record them and report them to us. Therefore in the future ubiquitous services, location estimation will be a key...
Nowadays, users of mobile phones generate too many files that have to be frequently downloaded to an external storage repository (freeing local space), using a USB cable or a short-range wireless connection such as Bluetooth. This situation is very common in developing countries where there are not many available wireless networks, restricting the user mobility. This paper presents an Internet File...
Rapid development has equipped mobile devices with heterogeneous wireless access capabilities. A lot of work has been done on WLAN-3G integration to support seamless connectivity and global roaming. Most recent research trends focus on interwork gateway or intersystem roaming framework. In this paper, we introduce an application framework providing seamless connectivity for mobile devices across heterogeneous...
Along with the rapid development of 3rd generation mobile communication technologies, the applications of M-Commerce have been greatly expanded. Based on the research and analysis of the J2ME platform, this paper proposes a secure architecture for M-Commerce systems under the 3G networks. The proposed solution is the combination of J2EE and J2ME capabilities based on the three-tier architecture, as...
Nowadays, users of mobile phones generate too many files that have to be frequently downloaded to an external storage repository, restricting the user mobility. This paper presents a File Transfer Service (FTS) for mobile phones with scare storage resources. It is a support that can be used through a set of functions (API) that facilitates file transfer between mobile applications and external storage...
Mobile services are prone to failures caused by the disruption of an active wireless access network connection due to the user’s movement to other networks or signal blocking (shadowing). Thus, proper mechanisms for disconnection tolerant mobile application services are needed. In this paper, we propose a middleware framework that transparently performs required functionality for users in order to...
Mobile learning is an increasingly important source of educational material. However, only scant research has been directed towards how this educational information can be made accessible to the deaf and hearing impaired communities. Sign language is an effective method of communication for normal people to communicate with these two groups. In this paper, we propose to develop a sign language learning...
