Abstract: A communicating method of a communication device for connecting to a first network and a second network includes: when a rescheduling condition is reached, rescheduling a wake up period of the communication device for the first network at least according to a wake up period of the communication device for the second network; wherein the wake up period of the communication device for the first network is rescheduled by making the communication device a master device in the first network through adjusting a preference parameter of the first network.

Abstract: A method of data communication for a communication device in a wireless ad hoc network is disclosed. The method comprises receiving a service publish message and a service subscribe message from a first communication device of a first service cluster and a second communication device of a second service cluster respectively, wherein the second communication device subscribes a service from the first communication device, and establishing a third service cluster including the first communication device and the second communication device, wherein a schedule of the third service cluster for the communication device, the first and second communication devices of the third service cluster to wake up for data transmission and reception is determined by the communication device or coordinated by the communication device, the first and the second communication devices.

Abstract: A device-centric discovery mechanism requiring very low power consumption to find out information about each other directly in a self-managed mobile environment is proposed. A mobile communications device joins a self-managed communications network, which does not have a centralized management entity. The mobile device receives a request from a peer communications device about publishing a service or subscribing to a service in accordance with a first schedule. The mobile device announce the request on behalf of the peer communications device in accordance with a second schedule. The service is then provided by a service advertiser to a service seeker in accordance with a third schedule.

Abstract: A communicating device includes: a first packet detector and a second packet detector, wherein the first detector is arranged to detect a first preamble included in a first response packet over a first sub-channel; and the second packet detector is arranged to detect a second preamble included in a second response packet over a second sub-channel. The second sub-channel is different from the first sub-channel, and the first packet detector and the second packet detector co-exist in the communicating device.
