摘要： The present invention relates to a bio-inspired distributed wireless resource allocation, and a method of solving a conflict of a firing phase allocation in the bio-inspired distributed wireless resource allocation includes (a) selecting a reference firing phase having a preset degree of allocation-available space, on the basis of firing phase allocation information within a received firing message, when a newly-entered node attempts the firing phase allocation, (b) calculating changeable positions of the reference firing phase and a succeeding firing phase of the reference firing phase under assumption set based on the firing phase allocation information, and (c) setting a space between the changeable positions as an allocation-available range and allowing the newly-entered node to be allocated with an arbitrary firing phase within the allocation-available range.

摘要： A system for downlink transmission using heterogeneous power includes a plurality of sensor nodes, a coordinator connected to a network including the plurality of sensor nodes and configured to transmit data to the plurality of sensor nodes, a power source configured to supply power required for the coordinator to transmit data to each of the plurality of sensor nodes through a single transmission passage at a position away by a specific distance from the network, to the coordinator, and a battery configured to supply power required for the plurality of sensor nodes to perform communication within the network, to the plurality of sensor nodes, wherein when a destination node as a reception target of the data, among the plurality of sensor nodes, receives the data, the destination node transmits a signal indicating the data reception to the other remaining nodes among the plurality of sensor nodes.
