【摘要】：在感知无线云网络中,针对感知用户数据传输时发生冲突造成能量浪费问题,给出了一种移动云计算辅助下基于感知数据传输时间优化的终端节能方案。通过云平台强大的计算处理能力对感知用户业务量进行统计分析,并导出了不可靠检测区域;在此基础上,采用感知用户不可靠检测概率为目标函数,使不可靠检测概率最小的同时,计算出感知用户最佳的数据传输时间,并根据业务量对感知用户的传输时间进行自适应调整,实现对感知用户的宏观调控,从而节约系统中感知终端的能耗。仿真结果表明,该方案使得感知用户的碰撞概率降低,提高了感知用户数据传输可靠性,并降低了由于数据碰撞造成的终端能耗。
[Abstract]:In perceptual wireless cloud networks, a terminal energy saving scheme based on the time optimization of perceptual data transmission under mobile cloud computing is proposed to solve the problem of energy waste caused by the collision of perceptual user data transmission. Through the powerful computing and processing power of cloud platform, the perceptual user traffic is statistically analyzed, and the unreliable detection region is derived, on the basis of which, the probability of perceived user unreliable detection is used as the objective function. When the probability of unreliable detection is minimized, the optimal data transmission time of the perceived user is calculated, and the transmission time of the perceived user is adjusted adaptively according to the traffic, and the macro-control of the perceived user is realized. Thus, the energy consumption of the sensing terminal in the system can be saved. The simulation results show that the proposed scheme reduces the collision probability of the perceived user, improves the reliability of the data transmission of the perceived user, and reduces the terminal energy consumption caused by the data collision.
