Authentication of Medical Documentation with Privacy Protection and Sharing in Cloud

There is a growing need for better medical care as a result of the adoption of clever electronic gadgets and the development of cloud and cloudlet technologies. Data collection, storage, and dissemination are the three main steps in the medical data processing chain. The traditional healthcare system frequently requires the transfer of medical data to the cloud, resulting in the use of sensitive user data and communication energy. The exchange of medical information is a crucial and difficult problem. In this study, we suggest a brand-new human services framework that makes use of cloud let's flexibility. Security assurance, information sharing, and intrusion detection are among the components of cloudlets. We apply the Number Theory Research Unit (NTRU) technique to encrypt the user's bodily data gathered by wearable devices during the data gathering phase. This information is then efficiently transferred to nearby cloudlets. We also present a trust model to help users choose reliable partners that want to share cloudlet-stored data.

An efficient mobility prediction model for resource allocation in mobile cloud computing

Mobile cloud computing (MCC) is a technology which provides cloud server resources to mobile users with optimized latency. MCC allows mobile device to access cloud resources and to offload tasks to cloud let servers at any time and from anywhere. The cloud let servers are attached to wireless Access points. But mobility plays an important role which leads to the loss of connectivity of mobile devices because of varying signal strengths. On the other hand, optimal code execution is a challenge. In this paper, a connectivity base mobility prediction method is proposed to assign the cloud resources to the user without loss in the connection. The past accessing history of the users and path loss factors are taken into consideration to predict proper access point. From the performance evaluation the performance of the proposed method is increased by 15.23% when compared to other existing methods.

Privacy Protection for E-Health Records Over Mobile Cloudlet

Preparing of therapeutic data for the foremost half incorporates operation, data storage and data sharing etc. Usual social services framework often wants the conveyance for restorative data to cloud which incorporates purchasers touchy information and cause correspondence. For intents and functions, restorative data sharing is basic and testing issue. Be that because it could, there has been protection worries as on the brink of home well-being information can be bestowed to those outsider servers, and to unapproved parties. To ensure the patient's authority over accessing their Personal Health Records (PHR), it is a promising strategy to cipher the PHR before reappropriating. However issues, as an example; danger of protection introduction, ability in key administration, adaptable access, and skillful client denial, have remained the foremost very important difficulties towards accomplishing fine-grained, typographically approved data gets to regulate. During this paper, we tend to propose a completely unique patient driven system and a set of parts for data gets regulate to PHR place away in semi confided in servers. To accomplish fine-grained and versatile data gets to regulate for PHR, we tend to influence Attribute based encryption coding (ABE) strategies to cipher each patient's PHR document. Distinctive in respect to past works in secure information redistributing, we tend to center on various data owner state of affairs, and gap the purchasers within the PHR frame-work into numerous securities areas that very lessens the key administration many sided nature for proprietors and purchasers transportable cloud let. A high-level of patient protection is ensured whereas by misusing multi-specialist ABE. Our commit to boot empowers dynamic modification of access strategies or record qualities, bolsters effective for the asking client/characteristic repudiation and break glass access below crisis things. Broad scientific and trial results as displayed that demonstrate the protection, ability, and productivity of our set up.

Context dependent off loading for cloudlet in mobile ad-hoc network

Cloud Computing in Mobile Ad-hoc network is emerging part of research consideration as the demand and competency of mobile devices increased in last few years. To follow out operation within the remote cloud builds the postponement and influences the administration standard. To keep away from this trouble cloudlet is presented. Cloudlet gives identical support of the devices as cloud at low inactivity however at high transfer speed. Be that as it may, choice of a cloudlet for offloading calculation with flat energy is a noteworthy test if multiple cloud let is accessible adjacent. Here I proposed energy and bandwidth (Traffic overload for communication with cloud) aware cloudlet selection strategy based on the context dependency of the device location. It works on the basis of mobile device location and bandwidth availability of cloudlet. The cloudlet offloading and selection process using given solution is simulated in Cloud sim Simulator.

Task Scheduling tn Cloud Computing using Various Techniques

Cloud computing has become buzzword in computer industry as it provides scalable, reliable and economical services to the users. For better performance of cloud computing it is crucial that an efficient task scheduling algorithm is in place. Scheduling algorithms allocates the resources to the user’s task i.e. it provides mapping between resources and tasks. Scheduling in cloud is NP-hard problem because of large solution space available. Meta-heuristic algorithms have become the most famous scheduling approaches as they provide near optimal solution in short span of time. This paper surveys the various approaches for cloudlet scheduling. It also classifies the various approaches based on the objectives considered for optimization.

Analytical performance models for resource allocation schemes of cloudlet in mobile cloud computing

In the cloudlet architecture of mobile cloud computing (MCC), the mobile users offload their resource-intensive tasks to a local cloud (i.e., Cloudlet) via WiFi connections, to overcome the resourc...

The Silver-Blue Cloudlets again

FROM your last week's issue, p. 264, it would seem that the silver-blue clouds and cloudlets seen at midnight low down over the northern horizon both in this, and last, year's July are attracting much attention among your correspondents; but have not yet had the spectroscope directed to them.
