RMAC: A Reliable Multicast MAC Protocol for Wireless Ad Hoc Networks
Overview This paper presents a new MAC protocol called RMAC that supports reliable multicast for wireless ad hoc networks. By utilizing the busy tone mechanism to realize multicast reliability, RMAC has the following three novelties it uses a variable-length control frame to stipulate an order for the receivers to respond, such that the problem of feedback collision is solved; it extends the traditional usage of busy tone for preventing data frame collisions into the multicast scenario; and it introduces a new usage of busy tone for acknowledging data frames. This paper also generalizes RMAC into a comprehensive MAC protocol that provides both reliable and unreliable services for all the three modes of communications: unicast, multicast, and broadcast.
