“…One major concern in mobile connectivity is how to efficiently access cloud-based applications when using a resource-constraint mobile device, where essentially applications require a continuous Internet connection that is difficult to obtain in challenged environments (lack of communication, interference access networks and even areas with high costs of Internet roaming) [Pal, 2016]. Some researchers have started to explore and analyse existing solutions in order to understand the relevance, innovation and future prospects of this field.…”

“…Some researchers have started to explore and analyse existing solutions in order to understand the relevance, innovation and future prospects of this field. For example, [Pal, 2016] explore the emergence of extending cloud-based applications with mobile opportunistic networks in challenged environments and observe how local user's social interactions and collaborations help to improve the overall message delivery performance in the network. On the other hand, [Tsai, et al, 2010] Bluetooth [Fernando, et al, 2013].…”

“…Finally, when focusing on mobile devices and the intent they deliver services, a variety of communication procedures can be found, such as a "Device to Cloud" (D2C), "Cloud to Device" (C2D) and "Device to Device" (D2D) [Pal, 2016]. In D2C architecture approach, mobile devices connect to the cloud through an Internet connection and the data storage and processing happens outside the mobile devices; In C2D approach applications run inside the mobile devices and are executed at the edge of the mobile network; the D2D approach is done through a direct communication between nearby devices that aim to improve information availability and energy efficiency [Pal, 2016] [Alam, et al, 2015]. Researchers have been developing different architecture approaches that follow these classifications models:…”

“…[Verbelen, et al, 2012] presents a 'cloudlets' approach, where cloud-based applications have moved nearer to the user's mobile devices in the form of 'small data storage'. Cloudlets are used for mobile devices due to its widely dispersed and decentralised Internet infrastructure and the ability to provide a high bandwidth of network utilisation [Pal, S. (2016)]. The proposed architecture reduces the bottleneck of wireless communications and improves latency, since it introduces a 'pocket cloudlet' where full or a part of the cloud-based applications is stored inside the mobile device.…”

Mobile devices led to a new generation of applications that exploit their intrinsic mobility, proximity to the user, and dependence on handled devices. However, in the current technological landscape, companies face problems associated with the development of mobile applications and rapid integration with their enterprise systems to ensure value-added services to its customers. Furthermore, there are still problems with the availability and quality of communications, establishing itself as an obstacle to the provision of highly integrated applications on always-connected environments. The connectivity problem in mobile devices is generalizable and in this sense an abstraction can be created with reduced implications in the development and adaptation of existing applications to allow the services availability of the applications in highly variable environments. To fill this gap, we propose a generic model for dynamic switching of communication channels to ensure the principles of transparency in distributed environments by: (1) designing an interchangeable communication layer for mobile applications; (2) ensuring the transparency of the communication channels; (3) proposing a framework for the development of mobile applications in distributed environment to guarantee the upper cited communication transparency. Therefore and in order to support the proposed model a research is presented with mobile users of various ages and nationalities as a way of motivation for the current thesis, which allowed to measure its importance and framed the implementation of the case study that validated the proposed model and architecture using software engineering methodologies.

With the popularity of smartphones and upsurge of mobile applications, mobile devices have become prevalent computing platform. Although MCLOUD paradigm solves the problem of limited resources constraint of mobile system and unavailability of internet, through several offloading technique. Nevertheless, mobile users are still reluctant to adopt this paradigm, due to security concerns of their data. This research provided security on the users task and still minimize the total computational time of the MCLOUD. Tasks were programmatically broken down into smaller tasks and encrypted using homomorphic encryption system and assigned to slave devices which were admitted into the MCLOUD during the resort point process through the WIFI Direct wireless network. Using a test bed of three (3) smartphone devices, several task sizes ranging from 2KB, 4KB up to 20KB were used to test the implemented security framework and the time taken to complete computation of each task size is recorded for both MCLOUD and standalone architecture, the total execution time was compared and findings shows that computation involving security on MCLOUD takes less time compared to computation on standalone devices, the following readings were recorded. For the 4KB task size, MCLOUD spent 48500microseconds while standalone spent 241000microseconds; for the 6KB task size, MCLOUD spent 99500microseconds while standalone spent 453000microseconds; whereas in the 8KB task size, MCLOUD spent 109500microseconds while standalone spent 553000microseconds,which is approximately five (5) times faster than standalone execution. MCLOUD framework was observed to have a lower computation time, decreasing computational time ratio, higher throughput per seconds, It was discovered that computation on distributed encrypted data (MCLOUD) using homomorphic encryption is safer and faster than standalone single device computation.

Nowadays, there is tremendous growth in the Internet of Things (IoT) applications in our everyday lives. The proliferation of smart devices, sensors technology, and the Internet makes it possible to communicate between the digital and physical world seamlessly for distributed data collection, communication, and processing of several applications dynamically. However, it is a challenging task to monitor and track objects in real-time due to the distinct characteristics of the IoT system, e.g., scalability, mobility, and resource-limited nature of the devices. In this paper, we address the significant issue of IoT object tracking in real time. We propose a system called ‘TrackInk’ to demonstrate our idea. TrackInk will be capable of pointing toward and taking pictures of visible satellites in the night sky, including but not limited to the International Space Station (ISS) or the moon. Data will be collected from sensors to determine the system’s geographical location along with its 3D orientation, allowing for the system to be moved. Additionally, TrackInk will communicate with and send data to ThingSpeak for further cloud-based systems and data analysis. Our proposed system is lightweight, highly scalable, and performs efficiently in a resource-limited environment. We discuss a detailed system’s architecture and show the performance results using a real-world hardware-based experimental setup.
