Abstract: An apparatus and method for hierarchical modulation and demodulation in a wireless communication network are provided. A hierarchical modulation apparatus may map information bits to a plurality of levels based on a predetermined level map, may generate an error verification code for each of the levels based on the information bits mapped to the levels, may generate coded information bits for each of the levels, and may map bits in a predetermined position among the coded information bits, to Pulse-Position Modulation (PPM) symbols in a sequence of the levels.

Abstract: Provided are low-power wireless communication apparatuses and a method thereof. A hub may receive a beacon signal from a neighboring hub that is within a predetermined area from the hub, and control an operation of a node served by the hub based on information received from the neighboring hub.

Abstract: A method and a target node for preventing collisions between networks communicating based on a carrier sense multiple access/collision avoidance (CSMA/CA) scheme, are provided. The method includes synchronizing an object network with a neighboring network. The method further includes allocating, to the object network, a slot index based on a number of the networks, and a contention window (CW) size. The method further includes setting, for the object network, a back-off counter value based on the CW size. The method further includes reducing the back-off counter value based on a channel state of the object network, and the slot index. The method further includes transmitting data related to the neighboring network based on the back-off counter value.
