Fig. 1From: On multi-copy forwarding protocols for large data chunk dissemination in vehicular sensor networksAn example to show the challenge in proposed scenario. The relay vehicle R1 holds an audio clip p1 to the destination vehicle D1 while the relay vehicle R2 tries to send a video clip p2 to the destination vehicle D2. Each vehicle can only hold one data content due to storage limitation. The arrows show their moving directions. a First, R1 meets R2. b Then, relays meet their destinationsBack to article page
