Our protocol adapts the error-control code and spreading factor on the links of a direct-sequence (DS) spread-spectrum packet radio network. The radios employ half-duplex transmission, and they operate with fixed power and bandwidth. There are no base stations, access points, or other infrastructure, and the protocol requires no power measurements or channel estimates. We compare the protocol with hypothetical ideal protocols that have perfect channel state information and maximize the throughput for each packet transmission.
