The authors study throughput-optimum localized link scheduling in wireless networks. The majority of results on link scheduling assume binary interference models that simplify interference constraints in actual wireless communication. While the physical interference model reflects the physical reality more precisely, the problem becomes notoriously harder under the physical interference model. There have been just a few existing results on link scheduling under the physical interference model, and even fewer on more practical distributed or localized scheduling. In this paper, they tackle the challenges of localized link scheduling posed by the complex physical interference constraints. By co-operating the partition and shifting strategies into the pick-and-compare scheme, they present a class of localized scheduling algorithms with provable throughput guarantee subject to physical interference constraints.
