利用多目标PSO优化的累积时延和信道容量联合优化的频谱切换算法
|
摘要
目前频谱切换中多以单目标优化设计目标信道,为了满足大容量实时传输要求,需要综合考虑累积切换时延和有效信道容量。对此构建了目标信道设计的多目标函数,提出了求解离散多目标优化问题的粒子群算法(DMOPSO),给出了种群编码、更新方式离散化设计。仿真结果表明,所提出的频谱切换算法得到的最优信道访问解集能够兼顾网络的实时性和高吞吐率,算法复杂度较低。
At present, a single target optimization function is often used in channel design. While in order to meet the large capacity real-time transmission, it is necessary to consider the cumulative delay and channel capacity simultaneously. The multi-objective function of the target channel design was constructed, and discrete multi-objective particle swarm optimization algorithm(DMOPSO) was proposed to solve it. The discretization design of the population coding and updating was given. The simulation results show that the optimal channel set obtained by proposed spectrum handoff algorithm can take into account the real-time and high throughput of the network, while needing the low complexity.
