Abstract

A resource allocation optimization for indoor Optical Wireless Communications is proposed. A smart coordinator tries to maximize the channel capacity by enabling or disabling the communication of the devices subject to system constraints. Binary Cuckoo Search and Genetic Algorithms were used in order to solve the binary NP-HARD optimization problem. The results show that the total channel capacity slowly decrease while the number of users increase. On the other hand, per-user capacity decrease faster than the total capacity. The minimum QoS of the system is achieved. Binary Cuckoo Search overcomes Genetic Algorithms when dealing with the proposed optimization problem.
OFDMA/VLC系统中QoS的增强
提出了一种室内无线光通信的资源优化分配方法。智能协调器试图通过启用或禁用受系统约束的设备的通信来最大化信道容量。采用二元布谷鸟搜索和遗传算法求解二元NP-HARD优化问题。结果表明,随着用户数的增加,信道总容量逐渐减小。另一方面,每个用户的容量比总容量下降得快。达到系统的最低QoS。二分布谷鸟搜索在处理所提出的优化问题时克服了遗传算法。
