In IEEE 802.11, multicast protocol is based on the basic access procedure of Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). This protocol does not provide any recovery mechanism for multicast frames. As a result, transmitted multicast frames may be lost due to collisions or errors. Recently, several reliable multicast protocols at MAC layer have been proposed for 802.11. They can...
In this paper, we study reliable multicast at the MAC layer for IEEE 802.11 wireless LANs. In IEEE 802.11, multicast protocol is based on the basic access procedure of carrier sense multiple access with collision avoidance (CSMA/CA). This protocol does not provide any recovery mechanism for multicast frames. As a result, transmitted multicast frames may be lost due to collisions or errors. Recently,...
