Fast and Low-Power Link Setup for IEEE 802.15.3c Multi-Gigabit/s Wireless Sensor Networks

초록

In this paper, we propose a polynomial-time framework for fast and low-power link setup between two 60GHz IEEE 802.15.3c wireless sensor devices. Due to the narrow beamwidth of 60GHz radio beams, the beam training procedure needs to evaluate a lot of search spaces. Thus, the running time to establish an IEEE 802.15.3c radio link is relatively longer than the running time of other schemes. In addition, evaluating a large search space requires a lot of training packets transmission, which increases the communication power consumption. Therefore, our proposed framework reduces the number of training packet transmission (i.e., the number of search space evaluation) using multi-resolution beam training for fast and low-power link setup.
