In this paper, we propose a QoS optimized power control approach to achieve an optimum multimedia communication quality over the InterPlaNetary (IPN) Internet with a strict energy consumption budget. The transmission power to send each frame is optimized by jointly considering the unequal distortion reduction gain of the multimedia data, energy consumption budget, and overall multimedia communication...
The transplantation and optimization of H.264 algorithm were introduced. The design principle of hardware and the approach of software module for video network server were analyzed, and the approach of developing network function with NDK was studied in detail. The system realized the real-time network video transmission of CIF format. The design is feasible and effective.
Selective encryption for video streaming was proposed for efficient multimedia content protection. However, the issues on joint optimization of video quality, content protection, and communication energy efficiency in a wireless sensor network (WSN) have not been fully addressed in the literature. In this paper, we propose a scheme to optimize the energy, distortion, and encryption performance of...
