Abstract: A method and an apparatus for predicting wired/wireless network traffics through probabilistic traffic characteristic estimation are provided to model characteristics of dynamically-changed traffics, and extract probabilistic characteristics of the traffic from limited sampling data, thereby probabilistically predicting effects of traffics, applied to a specific flow or a specific link, on service quality of the other flow or link for providing services within a network. A frame of a flow flowed into a variation band traffic within a preset time in wired/wireless networks is sampled(S601,S602). A probability distribution function for a continuous function corresponding to a histogram of continuous frame duration extracted through the sampling, continuous frame duration configured from frame pause period data and continuous frame appearance period is calculated(S609). Through the flow frame sampling increase, the probability distribution function of the continuous frame duration and the continuous frame appearance period is modified. Based on the modified probability distribution function, the traffic is predicted.

Abstract: A method and an apparatus for controlling congestion of a node constituting an ad hoc network are provided to reduce a packet loss caused by channel contention, improve throughput, and reduce attempts to re-transmit nodes. A monitoring unit divides channel states into a busy channel state and an idle channel state and monitors them(S210). When there is data to be transmitted during monitoring, a channel contention unit contend with neighbor nodes to obtain a channel(S220). In case of winning, a bandwidth calculation unit calculates a currently available bandwidth by using the busy channel states and the idle channel state(S230). A determining unit determines an amount of transmission data based on the available bandwidth(S240).
