    Comparative analysis of queue mechanisms with respect to various traffic in wired-cum-wireless network
    (Institute of Electrical and Electronics Engineers Inc., 2014) Dhadse, J.S.; Chandavarkar, B.R.
    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.

    Improving RED for reduced UDP packet-drop
    (Institute of Electrical and Electronics Engineers Inc., 2015) Mukund, Y.R.; Rohit, C.; Chandavarkar, B.R.
    This paper gives an understanding of how the Random Early Detection(RED) algorithm can be implemented in a network involving UDP sources. The User Datagram Protocol(UDP) protocol is an unreliable protocol and does not have the mechanism to detect the packet drops that are carried out by the RED gateway which results in a bias by the gateway against UDP packets. By manipulating certain parameters of the RED algorithm we can make the algorithm less biased against the UDP packets. Various methods have been simulated and their corresponding results are shown in this paper. The aim is to show that the algorithm can be used in a network which consists of both the TCP and the UDP sources. © 2015 IEEE.
