Abstract:
The IEEE 802.11 multicast protocol is proper to send data to multiple recipients. Nowadays, Wi-Fi equipped smart phones are in the access of almost every person which increases amount of data transmissions. In this paper, we discuss the flaws in existing IEEE 802.11 multicast protocol and propose an efficient way to improve its performance. The proposed system has an assisting station (AS) and the stations that want to join a multicast group have radio frequency monitoring (RFMON) modules which help themselves overhear the data. Thus, for multicasting, the access point (AP) transmits unicast data to AS by the fixed Internet protocol (IP) address while stations in multicast group can also receive the data. The proposed system improves efficiency and reliability, while reducing delay for multicast transmissions.
