Protocol for wireless networks

摘要

A wireless transmission method includes providing a commanding node and a plurality of sub-networks, each sub-network being assigned a priority level and including at least one responding node. Time slots are assigned to the sub-networks such that time slots assigned to each sub-network are interleaved in time with time slots assigned to at least one other sub-network. Within each time slot, at least one acknowledgement packet is transmitted from the at least one responding node before a command packet is sent from the commanding node within the time slot. Each at least one acknowledgement packet indicates whether or not a most recent command packet from the commanding node was correctly received by the responding node, whereby the command packet comprises a selection bit providing operational information taking into account the priority levels.
