A method and apparatus for energy adaptive resource allocation in energy harvesting network are provided. The method includes: allocating, by an energy adaptive resource allocation apparatus, non-competition slots of a next frame to at least one first wireless communication device whose energy queue state exceeds a predetermined threshold value among wireless communication devices succeeded in data transmission; and allocating, by the energy adaptive resource allocation apparatus, competition slots of the same number as that of at least one third wireless communication device expected to attempt data transmission to the next frame in consideration of a harvested energy amount and an average energy harvesting rate of at least one second wireless communication device.

Method and apparatus for energy adaptive resource allocation in energy harvesting network

The present disclosure relates to a method for joint random access control and resource allocation in a wireless communication system, and an apparatus using the same. A method for joint random access control and resource allocation in a wireless communication system includes estimating the total number of Machine Type Communication (MTC) devices, and determining at least one of an access control probability and an amount of resources to be allocated in a next frame depending on an amount of resources required to satisfy a random access delay requirement, by considering access control and resource allocation based on the total number of random access MTC devices.

According to the present invention, there is disclosed a method for reserving data transmission from a transmitting node to a receiving node in a receiver-initiated asynchronous MAC (Medium Access Control) protocol. The method includes receiving a base beacon frame from the receiving node and when transmitting a data frame to the receiving node, transmitting the data frame, with a reserved field value set in a portion of a header of the data frame.

Data transmission reservation method and apparatus, data reception method and apparatus, and data transmission and reception system in receiver-initiated asynchronous medium access control protocol

Disclosed are a method, an apparatus, and a system for collecting tags which may reduce recognition time and energy consumption as compared with a tag collection technology in an active radio frequency identification (RFID) system standard according to the related art. The method for collecting tags by an apparatus for collecting the tags in a RFID system, one collection round including: recognizing tags; and collecting data from recognized tags, wherein the recognizing of the tags comprises one scan period, and comprises repeatedly performing a scan process until the tags are recognized using a bit map indicating a recognition status of the tags within one scan period.
