Secure Video Multicast over Wireless Ad-hoc Networks using Network Coding

Video streaming over wireless networks has been continuously increasing, which results in significant energy consumption and growing security concerns, especially for safety-related services such as video surveillance. Advanced transmission and security mechanisms are required to improve video quality, protect video transmissions, and in the same time achieve energy efficiency. One of the promising solutions is to exploit network coding. In this research paper, we provide network coding aided transmission as well as security mechanisms, and compare them to non-network coding schemes. It is proved that using network coding is capable of significantly improving the achievable video quality, and reducing the computation complexity as well as signaling overhead for data encryption.
