Abstract
This paper proposes a new method for finding the available bandwidth of a path in multihop mobile wireless networks. The proposed method finds the link with the minimum current bandwidth and increases its bandwidth. This process is repeated until the bandwidth of the link with the smallest current bandwidth cannot be increased. Then the available bandwidth of the path is found to be the minimum of the current bandwidths of the links along the path. Extensive simulations are performed to compare the performance of the proposed method and that of the method which calculates the path bandwidth hop by hop. Our simulation results show that using the proposed method in a multihop mobile wireless network produces significantly lower call blocking ratio than the method which calculates the path bandwidth hop by hop.
