The aim is to give a solution of time slot synchronization in wireless Mesh networks(WMN).The traditional solution used full directional antenna in addition with asynchronous contention channel accession mechanism.The efficiency drops because interference between nodes became extremely worse when networks scale expanded.Nodes transmit and receive data in pre-allocated time slots and antenna to reduce interferences.It raised the efficiency a lot.Works are done about discussing features and advantages of synchronous WMN comparing with asynchronous WMN,and significance of synchronization accuracy to WMN.An algorithm of time slot syn-chronization based on GPS second pulse signal is proposed and realized on CPLD platform.
