Interference in wireless networks has traditionally been considered harmful. Thus, a traditional issue in wireless networks is to schedule network transmissions so that a receiver receives from only a single dominant transmitter. However, recent analysis has shown that allowing multiple transmissions to constructively interact at the receivers can achieve higher network throughput. In this talk, we investigate the feasibility of achieving practical, distributed constructive interference control in multi-hop wireless networks. We investigate the complexity issues and present a distributed algorithm that takes into account side information at both the transmitters and the receivers. Our technique is effective under a wide range of scenarios and can be viewed as a generalization of distributed MIMO and analog/physical layer network coding. Evaluations and implementation experiences using GNU radio will be reported. This talk is based on joint work with Rich Alimi (Yale), Dawei Shen (MIT), Harish Viswanathan (Bell-Labs), and Y. Richard Yang (Yale).
