无线传感器网络中能量有效的波束成形机制
Energy efficient beamforming scheme for wireless sensor networks
摘要
Abstract
Aiming at the limitation of energy and communication distance for nodes in wireless sensor networks and the characteristics of premature death due to ignoring the energy balance for traditional beamforming schemes, an energy ef-ficient beamforming scheme was proposed. First the impact of the number of nodes, the transmission coefficients, the li-mited power, and the arrival phase on the network energy consumption is analyzed, and the corresponding design prin-ciples are given. Then, the nodes which participate the beamforming are selected based on these principles and their transmission coefficients are adjusted according to their residual energy and phase. The analysis and simulation results show that the proposed scheme can effectively increase the number of successful transmission, balance the energy con-sumption among the nodes and prolong the network lifetime.关键词
