Bandwidth estimation in network probing techniques are playing vital role in today’s networks. It should satisfy a better quality of service (QoS). This is due to the service amendment of IEEE 802.11. The existing methodology is standardized to evaluate the amount of resources remaining on a given channel. It will be more helpful for bandwidth-constrained applications. The same methodology is not good due to potential non linearities in networks. The existing methodology uses min plus algebra of network calculus. In this project, we propose a new methodology for estimation of bandwidth performed by other state-of-the-art QoS protocols using the justification of min plus algebra technique and thereby developing a more versatile system.
