Abstract :
For multimedia communications such as video streaming, a QoS-guaranteed TCP (QoS-TCP) has been proposed and evaluated in characteristics of guarantee performance. For wired networks QoS-TCP can guarantee a target bandwidth against competitive back ground TCP traffic, depending on number of the competitive TCP flows and the target bandwidth. In this paper, the characteristics of QoS-TCP in mobile and fixed wireless networks are investigated through both computer simulations and real terminal experiments in both outdoor and indoor environments. Many wireless related factors such as radio interference and handover could affect the performance as well as buffer size and queueing behavior of access points. The experiment results show that QoS-TCP has a possibility to guarantee a target bandwidth, with depending on both the specified target bandwidth and mobile wireless environments (channel capacity).
