computing utilities. These services vary in the context of physical location, as well
as the distribution nature of requested data and resources. In this framework, a
cloud computing system can be classified as public, private, community-based, or
so-called social, hybrid or a combination of all the above, based on the model of

]. On the other hand, the lack of processing power and capacity
resources for mobile devices to efficiently manipulate 3D video content aggravate
the reliability for executing these resources in the mobile terminal and cause
capacity-oriented failures. Execution failures due to the lack of processing
resources should be adjusted through the offloading process and the resource/task
migration mechanism. In this context, a mechanism has to be investigated for
ensuring that the capacity of supplied resources can be expanded to meet the
needs of mobile devices for the efficient manipulation of 3D media content.
Based on the lack of resources for running and executing concurrent processes
associated with the efficient 3D video content manipulation over mobile devices,
this chapter elaborates on the resource migration according to a proposed cloud-
computing scheme. This scheme guarantees that the resource utilization, the oper-
ational efficiency, the portability of claimed resources, and the on-the-move fulfill-
ment of mobile users claimed tasks, in terms of memory for an efficient 3D video
content manipulation, are maximized. This is achievable through the dynamic task
migration, which enables partitionable 3D content associated tasks to be a-priori
migrated, according to the scheduling policy of the resource sharing process, in
order to avoid potential memory failures on a wireless device. In this framework, a
partitionable parallel processing cloud-rack system is studied, where partitions are
handled by a subsystem cloud rack that receives and handles the migration process
of the claimed resources.
The structure flow of this chapter is as follows: Sect.
7.2
describes related work
regarding cloud-based 3D media content, as well as highlights the need in adopting
a dynamic task migration scheduling policy based on capacity-awareness for
mobile computing environments. Section
7.3
presents the proposed migration
scheduling scheme that enables a cooperative mobile resources migration for
efficient 3D media content manipulation fulfilling the requested resources for the
mobile devices. Section

presents the results obtained, by conducting simulation
experiments for the performance evaluation focusing on the behavioral character-
istics of the scheme along with the system response. Finally, Section

concludes
this chapter, elaborating on research findings, as well as on potential future
directions.
7.2 Related Work and Research Motivation
The recent trend in multimedia content delivery through mobile computing plat-
forms is related with the adoption of procedures that efficiently manage the content
information. The main idea of multimedia content delivery is to obtain multiple
streams of content, transferred to various user-terminals by exploiting a number of
