【摘要】 能量协作是无线体域网的关键和热点问题,通过对基于能量收集的无线体域网能量协作问题研究,在无线体域网能量收集的通信系统中提出了一个能量协作的收集和转发协议,在该能量协作收集转发机制下推导并优化了通信系统的吞吐量。通过仿真实验来验证该能量协作收集转发机制对吞吐量性能的影响,仿真结果表明,通信性能不仅与传输功率有关,而且与通信时隙的活跃时间有关,验证了在实际的能量收集设备之间应用能量协作提高通信性能的有效性。更多还原

【Abstract】 Energy cooperation has become an emerging research topic of wireless body area networks.We investigate the problem of energy cooperation in wireless body area networks based on energy harvesting,and design an energy harvesting and transmitting protocol based on energy cooperation in wireless body area networks.We derive and optimize the throughput of communication system for the proposed protocol and evaluate its influence on the system throughput through the simulation experiments.The simulation results show that the performance is not only related to transmission power but also to the active time of communication duration,demonstrating the effectiveness of energy collaboration among actual energy collection devices on improving the performance of the communication system.更多还原
