Abstract: A transceiver device (50) acting as a master (2) among a plurality of communication devices (1 and 12) potentially acting as slaves to the master (2). The transceiver device (50) includes a transmitter (68), a receiver (54) coupled to the transmitter (68), and a processor (58) coupled to the transmitter (68) and the receiver (54). The processor (58) is programmed to poll the slaves at a first interval and then receive a communication request while polling from a first slave of the plurality of communication devices to communicate with at least a second slave of the plurality of communication devices. The master (2) then designates communication parameters for communication between the first slave and at least the second slave and then polls at a re-polling interval the first slave and at least the second slave to confirm the termination of communication between the first slave and at least the second slave.

Abstract: An "identical beacons" field ( 401 ) is inserted near the beginning of a transmitted beacon ( 403 ) that contains either an integer equal to the number of consecutive identical beacons sent (i.e., identical to the one presently being transmitted) or a repetition bit indicating whether or not the beacon contains changed information when compared to a prior-sent beacon. After sleeping awhile, a node ( 302 - 304 ) wakes up, receives a first portion of the beacon containing the identical beacons field, and analyzes the identical beacons field. Based on the analysis, the node makes a decision on whether to remain "awake" for reception of the remaining beacon or to return to sleep.

Abstract: A method and apparatus for reducing power consumption within a wireless receiver is provided herein. Particularly, the use of partial chip sequence correlation to reduce the average power consumption of a direct sequence spread spectrum (DSSS) wireless transceiver is provided herein. During operation, the receiver will attempt to correlate, or de-spread, less than all chips that constitute a symbol. A partial correlation may be performed on M chips, where M may be much less than N, the number of chips that represent a whole symbol. In a preferred embodiment, the M chips are the first M chips in the symbol.

Abstract: A direct sequence spread spectrum (DSSS) receiver (100) consistent with certain embodiments has a frequency generator (112) that generates a local oscillator signal without use of a piezoelectric crystal. A frequency converter (108) receives the local oscillator signal and mixes the local oscillator signal with a received DSSS signal to produce a down-converted signal. The received DSSS signal is encoded using a first set of DSSS code. A differential chip detector (116) receives the down-converted signal and converts the down-converted signal to a differentially detected signal. A correlator (120) receives the differentially detected signal and correlates the detected signal with a set of DSSS codes that are time-shifted from the first set of DSSS codes. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: When a candidate node (104) wishes to join a network (100), network access is either allowed or denied based on the candidate node's physical location. More particularly, a plurality of nodes associated with the network aide in locating the candidate node. Once located, a decision is made to either allow or deny network access based on the candidate node's physical location.

Abstract: A node (101) using a contention-based access scheme will monitor a channel for a predetermined condition. If the predetermined condition is detected, the node will defect from the contention-based access scheme (204), where any generated messages will be immediately transmitted. Should a second condition be met, the node will again follow the contention-based access scheme (202).

Abstract translation: 使用基于竞争的访问方案的节点（101）将监视预定条件的信道。 如果检测到预定条件，则节点将从基于竞争的接入方案（204）中缺陷，其中任何生成的消息将被立即发送。 如果满足第二条件，节点将再次遵循基于争用的接入方案（202）。
