What does cloud mean in mobile?
The mobile cloud is Internet-based data, applications and related services accessed through smartphones, laptop computers, tablets and other portable devices.
Mobile cloud computing is differentiated from mobile computing in general because the devices run cloud-based Web apps rather than native apps. Users subscribe to cloud services and access remotely stored applications and their associated data over the Internet.
mobile cloud computing extends cloud computing by providing enhanced service availability and by exploiting information about a user's location, context and network intelligence, thereby considerably improving user experience. Leveraging the mobile device storage, sensing and processing resources for optimizing cloud-based application also adds to better user experience.
The obstacles facing mobile cloud computing include limitation of wireless bandwidth capacity and fluctuations in network service delivery. Mobile technology assumes a shared bandwidth capacity, so that users within any particular mobile cell share the available bandwidth while accessing the data network, e.g. the Internet. To overcome this intrinsic limitation, and to address the increasing bandwidth demand, wireless networks are continuously being upgraded – with the IP-based 4G wireless broadband network technology as the ultimate long term goal.
