Comparative analysis of queue mechanisms with respect to various traffic in wired-cum-wireless network

Abstract

Current Active Queue Management (AQM) and TCP are designed to work well for wired networks where packet loss is mainly due to network congestion. In wired cum wireless networks, however, wireless bandwidth is much smaller than the wired network and at base station packet loss occurs due to bottleneck wireless link. As a result, the performance of TCP flows is significantly degraded. To overcome this problem, Base Station (BS) is the key point for performance enhancement in wired-cum-wireless network. There is need of AQM at base station which stabilize the system and achieve low delay, low packet loss, and high link utilization regardless the dynamic of network conditions. To study the behavior of Queue at base station, we carry out simulation of wired-cum-wireless network with respect to various traffics (Background, streaming, conversational) in ns-2. © 2014 IEEE.
