Abstract
A communication apparatus which, in an ad-hoc network, when receiving control packets from a plurality of terminals, can determine whether or not there is a collision among the control packets, and, based on the determination, can be prevented from continuing to be out of the network due to a collision among the control packets transmitted from the plurality of terminals. In the communication terminal, a communication section receives a control packet which periodically comes up on a communication path. When the communication apparatus receives a plurality of control packets which are defective in at least payload portions thereof within a predetermined time period, if a control section determines that source addresses included in header portions of the control packets which are defective in the payload portions thereof include a source address which is not identical to the other source addresses, the control section determines that the control packets are transmitted from a plurality of terminals and collide with each other.
