Performance Improvement of Mobile Adhoc Networkusing Energy-Bandwidth Aware Routing SchemeTechnique

Mobile ad-hoc network is made up of a large number of infrastructure-less wireless nodes. It takes a considerable amount of energy for a node to transmit and receive a huge number of messages. Shortage of sufficient bandwidth, energy, and queue size required to exchange the information can lead to congestion, which may increase transmission delay and packet loss. To address these issues, an Energy-Bandwidth Aware Routing Scheme (EBARS) is developed. EBARS monitors residual bandwidth capacity in network pathways, residual energy of the nodes, and available spaces in node queues to avoid congestion. By calculating the residual bandwidth, residual energy of the node, and queue length of the path, congestion may be prevented in advance, and the data rate of a sender node can be controlled accordingly. Before sending messages, the quantity of available and utilized bandwidth and the queue length cache must be computed.The Setdest utility is utilised to achieve node mobility, and the C++ language is used in the backend to enhance the routing protocol’s capabilities. Awk scripts are used to extract the findings from the trace files. The EBARS technique beats the BARS technique in packet delivery ratio, throughput, end-to-end delay, and packet loss parameters.
