ABSTRACT
IEEE 802.11-based networks have been able to provide a certain level of quality of service (QoS) by the means of service differentiation, due to the IEEE 802.11e amendment. There exists no mechanism or method that has been standardized to accurately evaluate the amount of resources remaining on a given channel. An evaluation of this kind would be a good asset for bandwidth-constrained applications. In multihop ad hoc networks this evaluation becomes even more difficult. The estimation of the available bandwidth still represents one of the main issues in this field. The proposed work provides an improved mechanism to estimate the available bandwidth in IEEE 802.11-based ad hoc networks. The estimation performed by other state-of-the-art QoS protocols, BRuIT, AAC, and QoS-AODV is also analysed. The scope of the proposed work is to reduce the collision and to improve the throughput value and finally the Bandwidth is estimated.
