Abstract
A routing control apparatus that constructs a transmission path for transmitting communication data in a wireless mesh network includes: a previous hop state managing unit that receives a first control signal for constructing a portion of the transmission path, and manages first information indicating operability, which is availability of a previous hop apparatus in a future, the portion being from a source apparatus to the routing control apparatus; an operation state managing unit that manages second information indicating operability of the routing control apparatus; and a routing control processing unit that compares the first information and the second information, and, if the operability of the routing control apparatus is higher than or equal to the operability of the previous hop apparatus, transmits a second control signal for constructing a remaining portion of the transmission path other than the portion.
