基于杂草优化算法的电力线通信系统资源分配
Resource Allocation for Power Line Communication System Based on Weed Optimization Algorithm
摘要
Abstract
In order to improve the resource utilization of the power line communication system, this paper proposes a modified Invasive Weed Optimization(IWO) algorithm to allocate resources. Under the criterion of Rate Adaptation(RA), the binary discrete IWO which has directed variation in the individual random position is proposed to realize the optimal subcarrier allocation, which not only meets the constraint of emission power spectrum, but also takes the fairness among users into account. In the environment of a typical power line communication system, simulation results show that, the modified IWO makes the power line communication system have greater throughput and better fairness, and improves the system performance effectively.关键词
