摘要： A communication unit (10) can have at least a first receiver (11) and a second receiver (12). The latter typically consumes more power than the former during ordinary operation. Pursuant to one embodiment a communication unit can use the lower-power receiver to detect energy on a monitored channel while the second receiver is retained in a reduced power mode of operation. Upon detecting an absence of channel activity the second receiver can be restored to normal operability to effect such activities as are then presently required.

摘要： Wireless sensor platforms (10), when deployed, can ascertain whether they can meaningfully participate in communications with more than one cluster (22, 23) of such devices. When true, such multi-cluster platforms can serve as bridge nodes to facilitate the passing of data collected from one cluster to or through another cluster. In a preferred embodiment, the platforms serving as bridge modes (24 and 25) utilize a communication schedule that imposes no greater work load than the load the platform would otherwise have served as an ordinary node, and preferably the workload is considerably reduced. This aids in ensuring that the portable power reserves of the bridge nodes will support bridge operations for at least as long as the clusters are otherwise functioning.

摘要： A method (600) performed by a packet scheduler of an access point (215) of adaptively resizing a scheduling window in a Quality of Service enabled Local Area Network (200) is disclosed. The packet scheduler schedules data packets for a given duration, termed a scheduling window. The packet scheduler according to an embodiment of the invention adaptively changes the duration of the scheduling window based on the QoS requirements of data packets to be transmitted to and from the access point (215). In particular, the duration of the scheduling window is changed based on the delay requirement of the data packet having the most constraint QoS requirement.
