ABSTRACT

The term bandwidth refers to the data rate that a network link or a network path can transfer. Bandwidth is one of the guarantee attribute to measure the performance of the network. Measuring available bandwidth in ad hoc networks is a challenging issue in Mobile Ad hoc Network (MANET). In this paper, the new technique is proposed to evaluate the accurate available bandwidth in ad hoc networks. This technique considers reducing backoff time, node’s and link’s capability. By these network flows, the amount of bandwidth is wasted. Estimating accurate available bandwidth allows a node to make an optimal decision before sending a packet in networks.
