Abstract: A method for visualization of a communication path includes: executing, by a processor of the node apparatus, a wireless communication processing that includes receiving a first frame transmitted wirelessly from a first node apparatus or a terminal apparatus, the first frame including first time information indicating a timing to cause the light emitting device to emit light, and performing at least either one of processing to utilize the path information to transmit the received first frame to a second node apparatus according to the path information and processing to terminate the received first frame according to the path information; executing, by the processor of the node apparatus, an application processing that includes causing the light emitting device to emit light, based on the first time information included in the first frame.

Abstract: A method executed by a wireless communication device used in a wireless ad hoc network includes: designating a bit in a loop detection array added to a received frame in accordance with identification information of the wireless communication device; deciding that a route in which the received frame has been transmitted is not a loop when the bit designated in the loop detection array is not used; deciding that the route is a loop when the bit designated in the loop detection array is used; updating the bit designated in the loop detection array to a state of being used and transmitting the received frame toward a destination node when it is decided that the route is not a loop; and returning the received frame to an adjacent node that is a local transmission source of the received frame when it is decided that the route is a loop.
