Abstract: In an apparatus and a method for controlling traffic for real time service between a wireless local area network (LAN) terminal and an access point in a wireless LAN system, a transceiver transmits and receives a packet to and from the access point, a signal-determination unit determines whether the packet to be transmitted/received via the transceiver is a real time packet, and a signal-controlling unit controls re-transmission according to transmission failure when the packet to be transmitted is determined to be a real time packet by the signal-determination unit. In this way, the invention maintains optimum traffic status in a wireless LAN environment, and lowers the risk of resetting the access point or the wireless LAN terminal. In addition, the invention prevents several coexisting wireless LAN terminals from interfering with real time traffic thereof and from delaying or corrupting voice and image data.

Abstract: A method for determining a transmission time of collected context information at a sensor node in a communication system that includes a client, at least one sensor node collecting context information, and an access point (AP) forwarding the context information received from the sensor node to the client. The communication system operates in a session layer of protocol layers of open systems interconnection (OSI). The sensor node calculates a transmission period in which the collected context information is transmitted, and randomly determines a transmission time at which the context information is transmitted within the calculated transmission period. Since the collected context information is transmitted at the transmission time randomly determined by the sensor node, the load on the AP can be balanced.
