The rapid spread of wireless mobile devices and the advances of wireless communication have fueled the interest about streaming 3D graphics on mobile devices to be used in augmented reality based classes of applications. In these types of applications, a real world is mapped into the virtual world and thin mobile devices are employed to navigate in the virtual simulated environment (VE). In evidence, one of the prime difficulties in 3D streaming over thin mobile devices consists of the limited mobile resources and capabilities, i.e., low processing power, limited storage capacity, limited graphics’ hardware and graphics’ accelerator making it very difficult for mobile devices to render and process large and complex 3D scenes. So far, a significant body of work has been dedicated to the challenges of mobile networks-based 3D streaming such as streaming performance, and bandwidth limitation. On the downside, very few studies have been committed to the mobile supplying partner strategies aiming at determining the peer that owns the correct information and that possesses enough bandwidth to send the required data quickly and efficiently to other peers in need. In this paper, we propose MOSAIC, our supplying partner strategy protocol for mobile networks-based 3D streaming. MOSAIC is based on the quick discovery of multiple supplying partners, by optimizing the time required by peers to acquire data, avoiding unnecessary messages propagation and network congestion, and decreasing the network bandwidth over utilization.
