Abstract
A multiple access and data channel scheme is presented for reducing network communication collisions and susceptibility to jamming signals in a distributed network to increase network connectivity and communication throughput. An order wire channel (202) is used to gain access to a data channel (204). To gain access to the data channel (204), a source radio sends a transmit probe (TXP) over the order wire channel (202) to the target radio. The target radio senses its environment and responds with a receive probe (RXP) which comprises data channel transmission parameters including the data channel frequency, transmit power, spread code, and transit timing to be used for the data transmission. Source radio moves to the data channel using the data channel transmission parameters specified by the receive probe (RXP) to communicate with the target radio. If a collision occurs of the order wire channel (202), the source radio retransmits the transmit probe after a random time period.
