The main objective of the proposed work is to provide an optimal routing in wireless communication in order to improve the better achievable data rates. High bandwidth routing is the most desired advantage in networks with portable nodes. The main objective is to attain a high bandwidth route for increasing the delivery rate in mobile adhoc networks (MANETs). Dynamic high bandwidth (DHB) nodes are selected for consecutive data transmission in MANETs by evaluating their available virtual channel bandwidth using channel rate. The total efficiency of a node is measured through the packets currently received by a node; the corresponding delay and the bandwidth estimated from that received packet. Thereby the routes are computed by this dynamic estimation to improve routing capability in MANETS. Performance analysis of this proposed DHB-routing system is achieved by using the Network Simulator (NS-2) tool. Copyright © 2019 Inderscience Enterprises Ltd.
