Adaptive Buffer switching in Ns2

ABSTRACT
There are various factors essential for the design of queue management schemes for routers: queuing delay, link utilization, packet loss, energy consumption and the impact of router buffer size. Buffers present in routers are responsible for holding packets during network congestion to enhance link efficiency and reduce packet loss. Wireless networks are challenged with a wide number of issues in comparison to wired networks and thus, it is important to deal with problems like high network delays and channel under-utilization that occur in fixed sized buffers. The modus operandi is to set the buffer size to the bandwidth-delay product (BDP) of the network. The main objective of this paper is to establish a high performance gain in order to achieve high throughput and low delay. The paper experiments with the proposed dynamic buffer sizing algorithms in 802.11 based wireless network buffer sizes. Experimental results reveal that the proposed algorithms have the ability to demonstrate better performance when compared to the existing methods of operation.
