A game apparatus repeatedly switches between a doze state in which a wireless communication function is restricted, and an awake state. The game apparatus stores unicast data and broadcast data acquired in the awake state, in a normal queue, and transmits the pieces of data to air in acquisition order. On the other hand, in the doze state, the game apparatus stores acquired broadcast data in a preferential transmission queue, and stores acquired unicast data in the normal queue. Thereafter, when the game apparatus becomes the awake state again, the game apparatus transmits the broadcast data stored in the preferential transmission queue in preference to the unicast data stored in the normal queue.

Systems and methods of preferential queuing by an information processing apparatus in a doze state

An apparatus and method are provided for saving power an independent basic service set (IBSS) comprising a master and a plurality of clients. According to the apparatus and method, a client of the IBSS receives a keyset packet from the master during an interval, the keyset packet including an aggregate of current client data, wherein the interval is a member of the group consisting of: a beacon interval and a coordination transmission interval. The client sends a key packet to the master during the interval, the key packet including new data from the client. The client contends for a shared wireless medium to send the key packet. The client enters an idle state for a duration of the interval after sending the key packet.

Channel-occupancy efficient, low power wireless networking

An apparatus and method are provided for efficiently sharing a single wireless channel and for providing improved power saving. Automatic beacon 'sliding' establishes a round-robin contention-free channel schedule among multiple IBSSs. Entering an idle state immediately following communication after a beacon saves power. Further power savings occur when presumptions of pending traffic may be made.
