Abstract:

To improve the spatial sharing gain in millimeter-wave wireless personal network (WPAN), an interference-aware beamforming mechanism (IBF) was firstly proposed, and then a maximum coexistence possibility algorithm (MCP) based on physical interference model was presented. With help of interference information obtained using IBF and link coexistence conditions derived under physical interference model, MCP could increase the spatial sharing gain by efficiently and exactly identifying the coexistence link set. Simulations show that the MCP algorithm outperforms the maximum sector number difference (MSND) algorithm based on protocol interference model and the blind algorithm based on physical interference model in terms of spatial sharing gain, and the comparative advantage increases along with the sector number and node number.

Key words: millimeter-wave wireless personal network, interference-aware beamforming, spatial sharing
