Collaborative Beamforming for Wireless Sensor Networks with Arbitrary Distributed Sensors

Collaborative beamforming (CB) has been widely used in a wireless sensor network (WSN) to improve the directivity of signals in long-distance transmission. CB performance has been analyzed for some specific node distributions such as Uniform and Gaussian distributions. However, the results obtained based on a particular distribution for a WSN under a specific condition may not be true for other WSNs under different conditions. This letter proposes a novel unified method to evaluate CB performance for various node distributions. The simulation results verify the proposed method.
