Node-Priority Based Resource Allocation in Wireless Mesh Networks
-
摘要: 随着网络负载的增加,多射频多信道(MRMC)无线Mesh网络的性能也随之下降。为减小网络中的拥塞和干扰,提升网络性能,综合考虑链路干扰和链路负载,提出了一种基于节点优先级策略的信道资源分配(NPFCA)方案,并引入离散粒子群优化(DPSO)算法对NPFCA进行快速迭代收敛。仿真在不同的正交信道数以及不同网络负载下进行,结果表明,该NPFCA方案在不同网络条件下,其吞吐量较传统的CCA和C-HYA算法分别具有32.9%~73.3%和5.5%~17.0%的提升。
