    摘要: A method (200) for enabling compatibility of wireless devices having different regulation settings. The method includes upon initialization of a wireless device, scanning a predefined common channel (S220); forming a WiNet service set (WSS) by wireless devices communicating over the predefined common channel (S230); upon switching of the wireless devices in the WSS to a channel other than the predefined common channel, checking if a new wireless device attempts to join the WSS (S240, S250); and adding the new wireless device to the WSS if such attempt was detected (S290).

    摘要: A communication system includes first and second devices, where a processor of at least one of the first device and the second device is configured to establish a superframe having a superframe duration (Ts) and transmit a beacon by the first device during each of the superframe duration (Ts); scan by the second device all sectors (Nbeam) by scanning each sector for a superframe duration (Ts) and repeating a jump sequence. The jump sequence has a sequence duration (Ttotal) which is equal to a sum of a control duration (Tc) of a control channel and durations of data channels (KTd). The processor is further configured to find the first device by the second device during a find time (Tf), where the control duration (Tc) is greater than the durations of data channels (KTd).

    摘要: In a communication network (100), a method (400) of reserving X slots (610) for transmitting data from a source device (110A) to a destination device (110D) via multi-hop relay includes sending a first hop reservation request from the source device (110A) to a second device (110), for transmitting data from the source device to the destination device. The first hop reservation request identifies the source device, the destination device, and X proposed slots (610) to be reserved for the first hop. The source device then receives a first message, addressed to the source device from the second device, indicating that the first hop reservation request is pending and that the X slots proposed by the source device have been reserved by the second device. Later, the source device receives a subsequent message indicating whether a final hop reservation request has been accepted by the destination device.

    摘要: A wireless device (A) in a first antenna sector (40) is discovered using a directional antenna (322), which sends and receives signals in multiple antenna sectors. Multiple primary beacons are transmitted in corresponding primary beacon time slots (1P-4P), which correspond to the antenna sectors (10-40) and have associated secondary beacon time slots (1s-4s). A secondary beacon is received from the wireless device in a first secondary beacon time slot (4sA) associated with a first primary beacon time slot (4P) corresponding to the first sector, the secondary beacon being responsive to a first primary beacon included in the first primary beacon time slot. An additional first secondary beacon time slot (4s) is added in association with the first primary beacon time slot. The additional first secondary beacon time slot enables an additional wireless device in the first sector to send an additional secondary beacon in response to a subsequent first primary beacon included in the first primary beacon time slot.

    摘要: The present invention provides a system (600), device (500) and method (400) for automatic partner selection in an existing Cooperative MAC (CMAC) protocol, which uses the Ready-to-Send (RTS), Clear-to-Send (CTS) and Partner-Clear-to-Send (PCTS) handshaking to establish cooperation. The present invention enables a “best” partner/relay (500.R.k) who is also willing to cooperate to relay information to a destination (500.D.J) for the transmitting device (i.e., the source), without the source (500.S.i) making a decision on partner selection. That is, the present invention provides a new mechanism by which the best partner/relay (500.R.k) that is also willing to cooperate will “step in” automatically without the source's involvement in selection of the partner/relay (500.R.k). This mechanism is contention-based and the partner is “selected” using local information only in a fully distributed manner.

    摘要: Under the present invention, a wireless component such as an access point or a mobile device is configured to manage the buffering of newly transmitted TCP packets. Specifically, the wireless component can receive both forwarded TCP packets and newly transmitted TCP packets. If a set of newly transmitted TCP packets is received out of order(i.e., before a set of previously transmitted TCP packets that must be forwarded), one out of order (newly transmitted) TCP packet will be passed for each of a quantity of tokens present on the wirelesss component. Each out of order TCP packet that is not passed will be buffered. Once a previously requested forwarded TCP packet is received and passed, the quantity of tokens is restiored to a predetermined quantity, and a commensurate number of buffered TCP packets can be passed.

    摘要: A method enables a wireless device (310) to rendezvous with another wireless device (320) through a wireless network (330), where activation schedules of the wireless devices are not synchronized. The method includes determining a number of time units in each cycle of multiple communication cycles, identifying active time units in each cycle during which the first wireless device enters an active mode, and identifying inactive time units in each cycle during which the first wireless device enters an inactive mode. The sum of the active time units and the inactive time units equals the number of time units in each cycle. A first active time unit in each cycle occupies a same position in the cycle as an active time unit in a previous consecutive cycle. Also, a second active time unit in each cycle occupies a different position in the cycle than any active time unit in the previous consecutive cycle.

    摘要: A method for deterministic directional discovery of neighbor devices by a device in a wireless network comprises dividing equally an access time to a discovery channel to predefined number of sector scanning periods (410), wherein each sector scanning period includes a predefined number of discovery sweep periods (430), and each discovery sweep period includes a pre-defined number of time slots (440); scanning the discovery channel in a single sector during a current sector scanning period (S310); transmitting a discovery frame towards each sector during each time slot of each discovery sweep period of the current sector scanning period (S320); checking if at least one response to a transmitted discovery frame has been received during the current sector scanning period (S330); and setting the device to scan the discovery channel in a next sector during a next sector scanning period, thereby sequentially accessing the predefined number of sector scanning periods (S35)
