Abstract
Provided is an apparatus and method for allocating time slots to nodes without contention in a wireless network. The method for allotting time slots includes: receiveing a packet length and maximum allowable latencies of the nodes and converting them into data in symbol units; determining a beacon order so that a beacon interval representing a length of a superframe is smaller than or equal to a minimum value of the converted maximum allowable latencies; determining a superframe order so that the sum of a length of a beacon frame, a length of a contention access period, and a length of contention free period is smaller than a length of an active portion, based on the converted packet length; and allocating a guaranteed time slot without contention to each node according to an allocation priority order for the nodes.
