    摘要: A method for optimizing data transfer in a wireless communication network is presented. A routing protocol is run for enabling data transmission devices (101-06) to form the wireless communication network. If routing information indicates that a route from a first data transmission device (101) to a second data transmission device (104) goes via at least one third data transmission (102, 103) device, it is checked whether a direct radio link (110) from the first data transmission device to the second data transmission device could be possible. If the direct radio link is possible, a message receivable by the at least one third data transmission device is sent. The message informs the third data transmission device that data transfer from the first data transmission device to the second data transmission device is direct radio communication and no forwarding actions are needed from the third data transmission device.

    摘要: A waveform and related devices and methods are disclosed for dynamic use of an air interface in a mobile ad hoc network. The waveform includes a dual preamble sequence enclosing self-discovery data that characterizes modulation for a subsequent data signal. The preamble is designed so that the circular correlation of the preamble sequence with itself is an impulse, and the first preamble sequence is a complex conjugate of the second preamble sequence. The preamble sequence can be used to bound a data packet on both sides so that detection of the impulse yields a window in which a data packet can be located, while the self discovery data provides information to extract the data signal from the wireless waveform. In one aspect, the preamble may be implemented using a CHIRP sequence that is a perfect square for more efficient implementation in a wireless modem. In addition, CHIRP sequences for different nodes can be generated with low cross-correlation to reduce interference among nodes in the MANET. The preamble may also support channel sounding or equalization to reverse amplitude or phase distortion in a channel.
