Abstract

Node deployment has an influence on energy dissipation of cooperative transmission scheme (CTS) in wireless sensor networks. In order to reduce the energy dissipation in single-hop wireless sensor networks, the problem of node deployment for cooperative beamforming (CBF) based CTS is studied in this paper. First, the energy dissipation for CTS based on CBF is studied, then the node’s position and the modulation size is optimized through two-step optimization to minimize energy dissipation. Numerical results show that the optimized node deployment and CBF scheme can greatly reduce the energy dissipation.

单跳无线传感器网络中基于协作波束成形的CTS节能节点部署优化

摘要

节点部署对无线传感器网络中的协作传输方案（CTS）的能耗有影响。为了减少单跳无线传感器网络中的能量消耗，本文研究了基于协作波束形成（CBF）的CTS的节点部署问题。首先，研究了基于CBF的CTS的能量耗散，然后通过两步优化来优化节点的位置和调制大小，以最小化能量耗散。数值结果表明，优化的节点部署和CBF方案可以大大降低能耗。
