摘要： A wireless network device includes an inactive mode clock, a transceiver module, and a control module. The transceiver module transitions the wireless network device from an inactive mode to an active mode. The transition occurs a wake-up period before an expected one of delivery traffic indication message (DTIM) beacons. The control module selectively adjusts the wake-up period during operation based on hardware/software delays of the wireless network device and drift of the inactive mode clock.

摘要： Methods and systems for providing location-aware WiFi access for a portable device include determining an initial location of the portable device and transmitting the initial location to a WiFi location provider, wherein the WiFi location provider comprises locations and WiFi parameters for a plurality of WiFi access points, wherein each WiFi access point has a corresponding wireless range. The locations and the WiFi parameters for a set of WiFi access points are then received from the WiFi location provider, wherein the set of WiFi access points are within a radius of the initial location of the portable device. At least one WiFi access point in the set of WiFi access points is scanned for that contains the portable device within its wireless range. The portable device then connects to the at least one WiFi access point, thereby forming a WiFi connection.

摘要： A protocol governing the operation of an ad-hoc WLAN enables each device in the WLAN to be configured as a registrar and/or an enrollee. Accordingly, each device is configurable. to support both the registrar as well as enrollee modes of operations. ID response to a time-driven user action, the device may be configured to enter into a registrar mode or an enrollee mode. While in the registrar mode, the device enters into an aggressive beaconing phase by setting its beacon contention window to a relatively very small value. The aggressive beaconing increases the probability of the discovery of the registrar by the enrollees. Optionally the device may prompt the user to select between a registrar and an enrollee mode of operation by displaying the option on an LCD panel.

摘要： A device previously configured as a registrar and that has established an independent ad-hoc network is automatically discovered by another device also previously configured as a registrar. To form an ad-hoc wireless network between these two devices, each device periodically enters a scanning mode to scan for and intercept beacons transmitted by the other device. Upon such interception, one of the devices becomes an enrollee in accordance with a predefined condition and in response to a user selected option. Subsequently, the enrollee modifies its beacons to include an attribute, such as the MAC address, associated with the other device. After intercepting the modified beacon, the remaining registrar prompts it user to decide whether to allow the enrollee to join the registrar's network. If the user responds affirmatively, a handshake is performed between the two devices and a subsequent attempt is made by the enrollee to join the registrar's network.

先前配置为注册服务商并建立了独立专用网络的设备由之前配置为注册服务商的另一设备自动发现。为了在这两个设备之间形成ad-hoc无线网络，每个设备周期性地进入扫描模式以扫描并拦截由另一个设备发送的信标。在这样的监听之后，其中一个设备根据预定义的条件并响应于用户选择的选项而成为登记者。随后，参与者修改其信标以包括与其他设备相关联的属性，例如MAC地址。拦截修改后的信标后，剩余的注册服务商提示用户决定是否允许参与者加入注册服务商的网络。如果用户作出肯定响应，则在两个设备之间执行握手，并且随后尝试登记者加入注册服务商的网络。

摘要： Symmetrical and asymmetrical ad-hoc, wireless networks and a method for saving power in the same may include causing a first station to determine whether a second station has a master capability to buffer data traffic for the first station. A first station requests the second station to buffer the data traffic intended for the first station for a first predetermined period. The first station enters a first power save mode, and the second station buffers the data traffic for the first station for the first predetermined period. The first station exits the first power save mode after the first predetermined period and the second station sends the buffered data traffic to the first station. Both the first and second stations may have master capabilities, or only one of the first and second stations may have a master capability.

摘要： An ad-hoc network approach for addressing ad-hoc network address assignment, name resolution, and service discovery in ad-hoc networks. The size of the ad-hoc network may be limited to a selected number of ad-hoc network stations. A first portion of the ad-hoc network address assigned to stations joining the ad-hoc network may be fixed and a second portion of the ad-hoc network address may be selected dynamically, as each new station joins the ad-hoc network. A station may generate an information element that may be included in ad-hoc network messages. An exemplary information element may include a last byte of the ad-hoc network address associated with the transmitting station, a 4-byte timestamp field which indicates a number of milliseconds since the station claimed the network address, a user-friendly name to identify the station, a universally unique identifier (UUID) for each service offered by the transmitting station, and a network-address-in-use bitmap.
