In this paper, it was explained that IEEE 802.11b WLAN system, communication method, and throughput measurement of the EI. Next, we measured the throughput of the WLAN influenced the CCI and the ACI. And we obtained the threshold value by analyzing measurement result. Finally, under the method of Direct Sequence Spread Spectrum (DSSS) in WLAN, it explained that why the throughput decreases and why...
In IEEE 802.16 Wireless MANs supporting OFDMA- PHY, random access with CDMA-based mechanism is proposed to request bandwidth for uplink data. Collision, which increases the Round Trip Time (RTT), is not avoided due to random access during requesting bandwidth among subscriber stations (SSs). In this paper, we propose an efficient resource allocation for Transmission Control Protocol (TCP) services...
Due to the growth of the wireless technology, demands on quality of service (QoS) in wireless networking have increased. Although IEEE 802.11e has been proposed for the support of the QoS, it still has weakness on the adapting varying profiles of multimedia traffic. Especially, Variable Bit Rate (VBR) streams cannot be supported in the current standard in terms of delay. In this paper, we first investigate...
