Abstract:
|
Mobile devices such as smart phones or tablets
are rapidly increasing their graphics and networking
capabilities. However, real-time visualization of 3D maps
is still a challenging task to accomplish on such limited
devices. In this paper, we describe the principles involved
in the design and development of a scalable client–server
architecture for delivering 3D maps over wireless networks
to mobile devices. We have developed a hybrid adaptive
streaming and rendering method that distributes the 3D
map rendering task between the mobile clients and a
remote server. This architecture provides support for efficient
delivery of 3D contents to mobile clients according to
their capabilities. As a proof of concept, we have implemented
a prototype and carried out exhaustive experiments
considering different scenarios and hundreds of concurrent
connected clients. The analysis of the server workload and
the mobile clients performance show that our architecture
achieves a great scalability and performance even when
using low-end hardware. |
