摘要
采用当前通信能耗控制算法处理窄带物联网切片资源时,缺乏对网络生命周期的考虑,导致出现网络生命周期短、通信延时较长和数据投递率偏低的问题。为解决上述问题,提出混合式窄带物联网切片资源通信能耗控制算法。考虑混合式窄带物联网的生命周期,根据网络节点能耗、平面跳数和节点度构建切片资源通信能耗优化模型。分析带电粒子在电磁场中的互相作用进行,调整粒子的电荷量,优化粒子群算法,利用优化后的粒子群算法求解能耗控制模型,并获得模型最优解,完成切片资源通信能耗的控制。仿真结果表明,所提通信能耗控制算法的应用下,网络生命周期更长,且通信延时较短,数据的投递率更高。
When the current communication energy consumption control algorithm is used to process narrowband IoT slice resources, it lacks consideration of the network life cycle, resulting in the problems of short network life cycle, long communication delay and low data delivery rate. Therefore, this paper presented an algorithm of controlling energy consumption of hybrid narrow-band IOT slice resource communication. With considering the life cycle of hybrid narrow-band IOT,a model of optimizing energy consumption of slice resource communication was constructed based on network node energy consumption, plane hops and node degree. The interaction of charged particles in electromagnetic field was analyzed. Moreover, the charge quantity of particles was adjusted, and then the particle swarm optimization algorithm was also optimized. Furthermore, the optimized algorithm was used to solve the energy consumption control model, and thus to get the optimal solution of the model. Finally, the control for energy consumption of slice resource communication was completed. Simulation results show that the network life cycle is extended by the proposed method. Meanwhile, the communication delay is shortened, and the delivery rate of data is higher than ever.
