    • Described herein are technologies that facilitate transfer of data-intensive content between portable telephones. Phones are configured to transmit data indicative of phone location to a proxy server by way of respective cellular network data connections. When a user of a phone wishes to acquire content that is labeled as shareable on another phone, the user of the phone initiates a location-based request, which causes the proxy server to provide a list of phones that are estimated to be in Wi-Fi range of such phone. The user thereafter selects a particular phone, and the proxy server instructs that phone to activate its Wi-Fi radio. The phone of the user additionally activates its Wi-Fi radio, and a peer-to-peer connection between phones is established. Thereafter, rich content is transferrable between the phones.
    • 这里描述的是便于在便携式电话之间传输数据密集型内容的技术。 电话被配置为通过相应的蜂窝网络数据连接将指示电话位置的数据发送到代理服务器。 当电话用户希望获取标记为在另一电话上可共享的内容时,电话用户启动基于位置的请求,这导致代理服务器提供估计为在Wi- Fi范围这样的手机。 用户此后选择特定的电话,代理服务器指示该电话激活其Wi-Fi无线电。 用户的电话另外激活其Wi-Fi无线电,并建立电话之间的对等连接。 此后,丰富的内容可以在手机之间传输。

    • Dynamic time-spectrum block allocation for cognitive radio networks is described. In one implementation, without need for a central controller, peer wireless nodes collaboratively sense local utilization of a communication spectrum and collaboratively share white spaces for communication links between the nodes. Sharing local views of the spectrum utilization with each other allows the nodes to dynamically allocate non-overlapping time-frequency blocks to the communication links between the nodes for efficiently utilizing the white spaces. The blocks are sized to optimally pack the available white spaces. The nodes regularly readjust the bandwidth and other parameters of all reserved blocks in response to demand, so that packing of the blocks in available white spaces maintains a fair distribution of the overall bandwidth of the white spaces among active communication links, minimizes finishing time of all communications, reduces contention overhead among the nodes contending for the white spaces, and maintains non-overlapping blocks.
    • 描述了认知无线电网络的动态时频块分配。 在一个实现中,不需要中央控制器,对等无线节点协同地感知通信频谱的本地利用,并且协作地共享用于节点之间的通信链路的空白空间。 共享频谱利用率的局部视图允许节点动态地将不重叠的时间频率块分配给节点之间的通信链路,以有效地利用白色空间。 这些块的大小可以最佳地打包可用的空白空间。 节点响应于需求定期重新调整所有保留块的带宽和其他参数,使得可用空白块中的块的打包保持主动通信链路之间白色空间的总带宽的公平分配,最小化所有的完成时间 通信,减少竞争白空间的节点之间的争用开销,并维护不重叠的块。
