摘要:
A wireless device transmits beacon packets at periodically occurring time intervals across a wireless channel. When the wireless communications device has not formed a piconet with one or more remote devices, the device scans the wireless channel for a predetermined amount of time immediately following each of the periodically occurring time intervals. During this time a remote device may respond to the beacon packet.

摘要:
A method, system and program code are provided to implement a wireless network having a plurality of devices in which one of the devices coordinates wireless communications between the devices. The method and system evaluates device parameters of one or more of the plurality of devices, the device parameters including at least available power source characteristics for a device; and determines a coordinator from the plurality of devices based on at least the available power source characteristics, such as an available power source capacity, for the one or more of the plurality of devices, the coordinator adapted to coordinate wireless communications between the devices in the wireless network.
摘要:
A wireless communications device detects a change in its residual energy status, and transmits the residual energy status across a wireless communications network to a remote device that coordinates communications in the wireless communications network. For example, the remote device may be a piconet coordinator (PNC) in an IEEE 802.15.3 network, or a master device in a Bluetooth network. A wireless communications device that coordinates communications in a wireless communications network (the coordinator) transmits one or more first handover commands to one or more remote devices upon the occurrence of a triggering event. Based on responses to these first commands, the coordinator selects a remote device for coordinating future communications in the wireless communications network.
摘要:
A method of coordinating devices in a wireless network is provided. First capability data associated with a first type of power source and a first state of the power source of a first device is received at a second device. Second capability data is transmitted to the first device from the second device. The second capability data is associated with a second type of power source and a second state of the power source of the second device. The first capability data is compared with the second capability data at the second device. If the comparison indicates the first capability data is less desirable than the second capability data, the second capability data is transmitted again to the first device from the second device. If the comparison indicates the first capability data is more desirable than the second capability data, the first capability data is received again from the first device at the second device.

摘要:
Generating a protected content stream from a data stream provides enhanced security in short-range wireless communications networks. This protected content stream is transmitted across a first short-range communications link. In addition, information for converting the protected content stream into the data stream is transmitted across a second link. The first link may be an ultra wideband (UWB) link, while the second link may be a Bluetooth link.
