Abstract

An apparatus and method for requesting channel time allocation in a coordinator-based network. The apparatus includes a controller generating a packet requesting channel time allocation required for reception of data from the coordinator and a transceiver that sends the generated packet to the coordinator. The packet includes information identifying that the device sending the packet is the device receiving the data.

Description

technical field [0001] The present invention relates to a wireless network system and method, more specifically, to a device and method for requesting channel time allocation (CTA) in a coordinator-based wireless network environment. Background technique [0002] As communication and network technologies advance, a wired network environment using wired media such as coaxial or optical cables is developing into a wireless network environment using wireless signals in various frequency bands. According to the transition from wired to wireless technology, computing devices ("wireless network devices") that include wireless interface modules, can realize mobility, and perform specific functions by processing various information are being developed, and are forming Wireless technology for efficient communication between wireless devices on the Internet. [0003] There are two main wireless network structures: infrastructure networks and ad-hoc networks. ...
