Message in Message (MIM): A Case for Reordering Transmissions in Wireless Networks

Message In Message (MIM) is an exciting development at the physical layer of IEEE 802.11. Two transmissions that otherwise conflict with each other, may be made concurrent with MIM. However, the benefits from MIM are not immediate. Higher layer protocols need to be explicitly designed to enable its inherent concurrency. This paper investigates the opportunities and challenges with MIM, and demonstrates a link layer framework to harness its potential.
