摘要

针对工业现场环境下无线传感器网络易受干扰而导致可靠性和吞吐量降低的问题

提出了一种基于单接口的多信道MAC层协议.该协议针对分簇式网络

采用改进的MMSN算法为各簇分配簇内通信基础信道

保证网内任意相邻簇信道互异

避免邻簇间的干扰

并在通信过程中根据实际信道质量和干扰强度动态分配簇内节点的通信信道

在抵御干扰的同时提高了信道的利用率.仿真结果表明

相比传统的MAC协议

该协议能有效提高无线传感器网络的吞吐量和抗干扰性.

Abstract

A single interface based multi-channel MAC protocol(SIMC)is proposed to avoid the decrease of wireless sensor networks' throughput and reliability caused by variable interferences in industrial environment. SIMC protocol achieves distributed network management by clustering. The cluster head nodes construct the fixed channel network with the improved MMSN algorithm

which ensures the difference of each adjacent cluster's channel. During the communication

cluster nodes switch channels based on the current channel's actual quality and interference intensity to resist external interference and improve the channel utilization rate. The simulation results show that the SIMC protocol can effectively increase WSN's anti-interference ability and throughput in comparison with traditional MAC protocol.
