Abstract
Mobile Ad-hoc network is a network grouped by large number of wireless mobile nodes. These nodes are capable of moving in random fashion and at any time these nodes could join and leave the network. Additionally, the quick development of IoT causes a more noteworthy measure of data transaction while the information’s are exchanged. This causes congestion especially in dense area which leads to delay in transmission also packet loss. And this may result an extreme issue where there is a more traffic huge system and high portability that authorize dynamic topology. In order to avoid this issue, we proposed the efficient Bandwidth Aware Routing Scheme. The proposed scheme settle the level of congestion in the network through bandwidth capacity monitoring and thereby cache the data. And also the calculation of availability of bandwidth as well as the bandwidth used for data transmissions must be done. Before data transmission, the residual cache also be calculated. This routing mechanism utilize the mechanism of feedback which informs about the traffic rate which helps to correct the data rate. These data rates will be modify depends upon the availability of bandwidth and the routing path queue. Using these strategies, we did simulations with the help of NS 2.35 tool where we used TCL for configuring the node and its deployment as well as mobility for data interaction. The outcomes delineates to demonstrate the strength of the proposed scheme over fundamentals in terms of Quality of Services (QoS) for Ad-hoc networks and the probability of congested node included both static as well as dynamic topologies.
