We propose procedures for autoconfiguration of wireless mesh networks based on DHCP protocol. The proposed mechanism provides automatic address and radio parameters set-up for nodes with multiple radio interfaces, allowing us to fully automatically form and to start a wireless mesh network, and to route packets. It supports mesh networks comprised of multiple IP subnets build with multiple networking technologies. Some performance issues of the autoconfiguration procedure are discussed. The autoconfiguration scheme was implemented and tested on OpenWRT platform.
