3 Abstract Proposal of routing method that improves transmission capability in WMN KOBAYASHI Wataru In recent years, Wireless Mesh Network have been forcused along with the popularization of mobile terminal and Wi-Fi. Wireless Mesh Network is expected as a temporary wireless infrastructure in a time of disaster beacause it can build a wireless netowrk to easily wide range. However, wireless mesh network has a problem. It is a problem that efficency of data transfer decrease due to control conmmunication increase than wireless network. Our reseach group have proposed routing method MBCR for improvement of efficency of data transfer by reduction of control communications. Tnis manuscript extended routing method that can respond to specific node placement, and confirmed performance of extended routig method. key words Wireless Mesh Network, MBCR ii
