Mobile Cloud Computing

Motivation Mobile devices (e.g., smartphone, tablet pcs, etc) are increasingly becoming an essential part of human life, Dream of “Information at your fingertips anywhere anytime”, Mobile devices still lack in resources compared to a conventional information processing device such as PCs and laptops

NIST Definition NIST Definition “A model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction”

4 Cloud Deployment Models Private cloud -Enterprise owned or leased Community cloud -Shared infrastructure for specific community Public cloud -Sold to the public, mega-scale infrastructure Hybrid cloud -composition of two or more clouds

Where is the MCC? Mobile Cloud Computing (MCC) at its simplest, refers to an infrastructure where both the data storage and the data processing happen outside of the mobile device. Mobile cloud applications move the computing power and data storage away from mobile phones and into the cloud, bringing applications and mobile computing to not just smartphone users but a much broader range of mobile subscribers”

Different Perspective for Architecture of MCC Agent-client scheme

Architectures of MCC

Protocol Model The concept model of cloud computing cannot be directly applied to the MCC. While MCC focuses on the connection between client and cloud, which may differ from common features of cloud computing.

Resource Scheduling Resource scheduling components address the schedule of resource, such as computing resource and storage resource.

Context Management Context Enabled features of mobile device allow us to ascertain additional information from the computing device itself without the need for explicit user input. Two major classes of contexts: Social Context, Spatial context

Two major approaches Application partition and offloading technology play an important role for the implementation of elastic applications. Application partition decompose complex workload to atomic ones, thus can be processed concurrently. Offloading application can free burden of mobile devices.

Advantageous of MCC

How MCC Can Extend Battery Lifetime? Challenges:

How MCC Can Improve Storage Capacity? Challenges

How MCC Can Improve Reliability? Challenges

Other advantageous of MCC Dynamic provisioning, Scalability, Multi-tenancy, Ease of integration.

Applications of MCC Mobile commerce, Mobile healthcare, Mobile learning, Mobile Gaming.

Mobile Commerce Mobile commerce (m-commerce) is a business model for commerce using mobile devices.

Mobile Commerce Some categories of M-commerce: Finance, Advertising, Shopping.

Mobile Learning (M-LEARNING) = (E-LEARNING) + Mobility

Mobile-healthcare Comprehensive health monitoring services, Intelligent emergency management system

Mobile Gaming Mobile game (m-game) is a potential market generating revenues for service providers. M-game can completely offload game engine requiring large computing resource (e.g., graphic rendering) to the server in the cloud, and gamers only interact with the screen interface on their devices.

ISSUES AND APPROACHES OF MCC ISSUES AND APPROACHES OF MCC

Issues in Mobile Communication Side

Low Bandwidth Solutions

Availability Solutions Finding stable neighbour WiFi multi-hop networking system G. Huerta “A virtual cloud computing provider for mobile devices,” in MCS, 2010. L. Zhang,, “WiFace: a secure geosocial networking system using WiFi-based multi-hop MANET,” in MSC, 2010.

Heterogeneity Solutions Context management architecture based on Intelligent Radio Network Access

Issues in Computing Side

Issue and Solutions in Computing Offload Offloading in the statistic environment is not always the efficient way to save energy For small calculation and depending on the transmission technology; Tradeoff between communication and computation cost.

Issue and Solutions in Computing Offload For the dynamic environment, offloading encounter new problems as Changing connection statues and bandwidth, Data may reach not to the end users.

Issues in Computing Side Security Security for mobile users, Security for mobile applications, Privacy Security of data on cloud Integrity Authentication,

Issues in Computing Side Security Security for mobile users, Security for mobile applications, Privacy Solutions Installing and running security software on the cloud.

Issues in Computing Side Security of data on cloud Integrity Authentication, Enhancing the efficiency of data access, Context aware mobile cloud services,

Open Issues Open Issues

How to combine the two technology seamlessly? The main aim of MCC is to provide PC_like services to mobile devices, How can the services from PC’s platforms be transplanted to mobile devices?

Low bandwidth Mobility of users Increasing the demand of mobile users, More Bandwidth is required to offer MCC.

Low bandwidth: 4G Solutions Increases bandwidth for subscribers up to 100 Mbit/s (for “LTE Advanced” standard) and 128 Mbit/s (for “Wireless MAN-Advanced” standard); Wider mobile coverage area, Quicker and reliable handoff, Varied services,

Low bandwidth: Femto Cells Solutions Provides very good coverage for small area with high capacity,

Low Bandwidth: Cognitive Radios Solutions Cognitive radio can be expected as a solution to achieve more spectrum utilization in mobile communication environnent and increase the bandwidth efficiency.

Handover (HO) in MCC Due to mobility of users, MCC encounters HO of users during the services Internetworking HO Intranetworking HO

Pricing Mechanism Using services in MCC involves with Mobile service provider (MSP) Cloud service provider (CSP).

Service Convergence The development and competition of cloud service providers can lead to the fact that in the near future these services will be differentiated according to the types, cost, availability and quality. A single cloud is not enough to meet mobile user’s demands. The new scheme is needed in which the mobile users can utilize multiple cloud in a unified fashion The mobile sky computing, will enable providers to support a cross-cloud communication and enable users to implement mobile services and applications.
