High-throughput interference-aware MAC protocols for heterogeneous ad hoc networks and multihop wireless LANs

In this paper, we propose the interference-aware multiple access (IAMA) scheme for medium access control (MAC) in ad hoc networks and multihop wireless LANs. We propose various components such as spread spectrum and collision prevention techniques for IAMA and other existing/future protocols to achieve interference awareness and collision control. IAMA is the first distributed MAC scheme that can support interference-aware and collision-free transmissions without relying on busy tone or dual transceivers per mobile device. Enabled by its interference awareness, IAMA can naturally support efficient power-controlled variable-radius multiple access, power engineering, and directional antennas.
