Abstract: A method for managing a broken node in a wireless personal area network (WPAN) game includes broadcasting alive check data for checking states of nodes from a master node having opened the WPAN game in a standby state of the WPAN game; receiving alive response data to the alive check data from the nodes; and having not received the alive response data from one of the nodes, determining that node as a broken node and broadcasting information as to the broken node to the other nodes. Other methods for managing a broken node in a WPAN game are also provided.

Abstract: A method for packet re-flooding in a wireless ad hoc network for transmitting a broadcast packet from a source node to a destination node. In order to determine the respective nodes received with the broadcast packet from the source node into a certain number of power levels in accordance with the receiving power of the signal carrying the received packet, the packet re-flooding method includes the steps of setting a power level reference by which the power level increases as the receiving power increases, obtaining the receiving power of the signal carrying the packet received from the respective nodes but not the source node, determining power levels based on the power level reference and the obtained receiving power, calculating a back-off delay time in accordance with the power levels of the respective nodes but not the source node, and re-flooding the received packet when the calculated back-off delay time of the respective nodes excluding the source node expires and when the received packet is the first packet that is received. Accordingly, the possibility of having collisions due to re-flooding of the respective nodes is reduced, and also, overall power consumption of the network decreases.
