Towards Optimal MAC without Message Passing in Wireless Networks
One of the key messages in significant research on cross-layer design of wireless networks over the past 15 years is that extensive message passing may be necessary to achieve optimal performance. Heavy message passing is obviously an undesirable feature for practical implementation due to its reduced actual throughput and security issues. In this paper, the authors first summarize their preliminary work that does not need message passing, yet achieves near-optimality. Then, they present their recent efforts to realize such an algorithmic solution in a real network, e.g., IEEE 802.11-based systems, and discuss possible future research directions.
