Summary:
In this paper, we have proposed a packet assignment scheme in a frame structure, which is suitable for video transmission using multicast distribution in wireless LAN systems. Multicast distribution transmits data packets to nearby receiving terminals using single transmission rate. The same data packet is simultaneously distributed to multiple terminals. However, there is a problem when multicast distribution is performed using a single transmission rate. The efficiency of the entire radio network decreases if packets fail to arrive at a receiving terminal far from the access point or if distribution to a faraway terminal occurs at a low transmission rate. The packet assignment scheme proposed in this paper is realized by assigning multiple transmission rates to packets that are encoded by scalable video coding in a frame structure to resolve this issue. we confirmed the performance of the proposed scheme by using an evaluation scheme, which evaluates metrics consisting of propagation parameter and quality of experience.
