Abstract
Multicast/broadcast is an important service primitive in
networks. The IEEE 802.11 multicast/broadcast protocol
is based on the basic access procedure of Carrier Sense
Multiple Access with Collision Avoidance (CSMA/CA). This
protocol does not provide any media access control (MAC)
layer recovery on multicast/broadcast frames. As a result,
the reliability of the multicast/broadcast service is reduced
due to the increased probability of lost frames resulting
from interference or collisions. In this paper, we propose
a reliable Batch Mode Multicast MAC protocol, BMMM,
which substentially reduces the number of contention phases,
thus considerably reduces the time required for a multi­
