Wireless ad hoc communication with different power levels for message header and payload |
摘要 |
A method of communicating messages among a number of radio communications devices via a communications medium, each of said messages comprising a message header and a message payload. The method comprises transmitting the message header of a first message, where the first message is to be transmitted from a first one of the number of radio communications devices to at least a second one of the number of radio communications devices, at a first power level high enough to enable each of the number of radio communications devices to receive the message header; transmitting the message payload of the first message at a second power level determined separately from the first power level to be high enough to enable the second radio communications device to receive the message payload. <IMAGE>
