Wireless Mesh Network (WMN) is a new wireless technology and it has the features of large area network coverage, Internet broadband access, self-healing, self-configuring and self-organizing. Routing is an important research issue in WMN. Many routing protocols are available in WMN. These protocols are divided into two categories proactive (table driven) and reactive (on-demand) protocols. This paper discusses the performance of proactive routing protocol Destination Sequenced Distance Vector (DSDV) in WMN by considering the various performance metrics (packet delivery ratio, routing overhead and dropped packets) by varying transmission rate and mesh client speed.
