Multi-hop wireless networks facilitate applications in metropolitan area broadband, home multimedia, surveillance and industrial control networks. Most applications require high end-to-end throughput and/or bounded delay. Current single-hop networks primarily employ random access link-layer protocols such as Carrier Sense Multiple Access (CSMA).

MAX is a time division multiplexed resource allocation framework for multi-hop networks with practical architectures for node scheduling algorithms. MAX tiling delivers optimal end-to-end throughput across arbitrarily large regularly structured networks while maintaining bounded delay. It outperforms CSMA-based random access protocols by a factor of 5-to-8. The MAX approach provides network services including: flexible uplink and downlink bandwidth management, deterministic route admission control, and optimal gateway placement. MAX has being implemented on IEEE 802.15.3 embedded nodes and a test-bed of 50 nodes has been deployed both indoors and outdoors.
