Abstract

A beamforming approach can be used in a wireless sensor network (WSN) to increase the effective communication range of the network. In this paper, the impact on array performance of node position deviations with respect to the ideal array element locations is examined and a distributed beamforming algorithm is proposed to compensate for these position deviations. Simulation results are provided to demonstrate that the proposed solution closely approximates the performance of an ideal uniform linear array.
