基于节点可信度的无线Mesh网络信道分配策略

目前很多无线Mesh网络（WMN）是以多信道、多接口环境搭建,如何进行有效的信道分配来提高网络性能是无线Mesh网络研究的重点之一.综合考虑了网络链路负载、节点可信度和链路干扰等因素,提出了一种基于节点可信度的无线Mesh网络信道分配策略（NTCA）对重要链路优先分配信道,从而降低链路冲突率.通过实验仿真表明,与随机信道分配策略相比,NTCA策略能有效降低网络冲突,提高网络性能.

A node trust based channel assignment scheme for wireless mesh network

Nowadays,a lot of wireless mesh networks were constructed with multi-channel and multi-interface.Channel assigned effectively to improve the performance of network is an important research area for wireless mesh network.This paper propose a node trust based channel assignment scheme（NTCA） to assign channel more effectively.The scheme considering many factors such as link load,node trust degree and link interference.It assign the important link prior,so it can reduce the link collision.Simulation results indicate that,compared with the random channel assignment strategy,NTCA can effectively reduce the network conflicts,and improve network performance.
