Resilient P2P multimedia exchange in a VANET

Multimedia exchange within a Vehicular Ad Hoc Network (VANET) may be facilitated by exploiting the peer-to-peer (P2P) paradigm. Urban VANETs are characterized by restricted vehicle mobility, driver actions, and bunching at obstacles, leading to wireless interference and broken links. Similarly P2P communication relies on distributed sources which are intermittently available. However, routing packets over multiple hops and multiple paths still results in packet losses, resulting in poor quality reconstructed video at a receiver. This paper proposes a slice compensation scheme employing spatial Multiple Description Coding to provide error resilience as a solution to these problems. Results show constant good quality video despite increasing packet loss ratios.
