煤矿井下无线传感器网络分布式信道快速分配算法

Distributed channel fast allocation in wireless sensor network

在深入分析现有的分布式信道分配算法的基础上,结合无线传感器网络节点分布的特点和网络架构等特征,通过采用接收者协议干扰模型和确定网络节点最小发射功率的方法,提出了基于网络拓扑最大链路边数的分布式信道分配算法CALENT.与现有的无干扰分布式信道分配算法Dis-Link的深入分析和对比研究表明,CALENT算法在同信道干扰指数和算法收敛速度等方面具有明显的优势,性能表现更为优越.

Based on in-depth analysis of the existing distributed channel allocation algorithms and by using the receiver protocol interference model and determining the minimum transmission power of the network nodes, this paper proposes an innovative fast distributed channel allocation scheme based on largest edges of network topology（CALENT） with the combination of distributed and architecture features. In compari- son with the existing distributed channel allocation algorithm Dis-Link, CALENT has better performance in co-channel interference index and convergence velocity.
