Abstract: The concept of bandwidth is central to digital communications, specifically to packet networks, as it relates to the amount of data a link or network path can deliver per unit of time IEEE 802.11-based networks have been able to provide acertain level of quality of service (QoS) by the means of service differentiation, due to the IEEE 802.11e amendment. However, no mechanism or method has been standardized to accurately evaluate the amount of resources remaining on a given channel. Such an evaluation would, however, be a good asset for bandwidth-constrained applications. It is reduce the collision and we want to improve the Throughput value and finally we find the Bandwidth.
In multihop ad hoc networks, such evaluation becomes even more difficult. Consequently, despite the various contributions around this research topic, the estimation of the available bandwidth still represents one of the main issues in this field. We propose an improved mechanism to estimate the available bandwidth in IEEE 802.11-based ad hoc networks. Through simulations, we compare the accuracy of the estimation we propose to the estimation performed by other state-of-the-art QoS protocols.
