Bhawana Pillai, Rakesh Singhai . Congestion Free Routing in MANET based on Node Reliability Supported AODV. International Journal of Computer Applications. 181, 49 ( Apr 2019), 35-39. DOI=10.5120/ijca2019918680
Abstract
In MANET nodes communicate using Adhoc On-Demand Distance Vector routing protocol(AODV). This protocol works on demand, when node wants to communicate, it starts finding the route by flooding the control packets and increases the network congestion. It’s a big challenge as the available channel bandwidth is limited. Earlier many congestion detection and avoidance technique were proposed but they were not feasible for all network situations in MANET due to its adhoc nature. The paper suggests the solution for the problem of congestion based on node reliability mechanism, to handle any type of network based on its size (small or medium) for the controlled communication in case of congestion. The paper proposes the local route repair and node reliability methodology for route establishment process and at the same time Clear To Send / Request To Send (CTS/RTS) mechanism is used to resolve the collision while multiple nodes are competing for the channels availability. Further congestion is minimized with the help of intermediate queue aware based data rate control technique in order to improve overall network performance. The results are taken in different scenario and analyzed the performance for the network parameters routing load, normalized routing load, packet delivery ratio and network throughput. Results demonstrated Packet Data Ratio(PDR) is near about 91 % as compared to normal AODV which is near about 84%. Also the throughput increased from 180 packets/sec to 300 packets/sec.
