摘要
基于协作通信技术,提出了一种协作路由策略,考虑了协作节点个数、星座体积和最优跳数的影响,通过理论证明和优化算法给出了其协作路由策略理想上限,并分析了其能量效率。理论分析及仿真结果表明,基于文中方案,通过选取合适的协作节点数和每跳距离可以有效提高无线传感器网的端到端能量效率,其性能要优于传统理想多跳路由方案。
Based on multiple-hop routing and cooperative communication technologies, a MISO- Based cooperative routing strategy is proposed and its energy efficiency is analyzed in this paper. We investigated the upper bound of energy consumption through the proof of theory and optimization algorithm. Theory analysis and simulation results show that based on the proposed method, by choosing appropriate cooperative node number, the constellation size and the distance per hop, the energy efficiency of wireless sensor networks can be improved effectively. The performance outperforms the traditional ideal multiple-hop routing scheme.
