Integrated Resource Adaptive On Demand Geographic Routing (IRA-ODGR) for MANET

It is a big challenge to develop routing protocol that can meet different application needs and optimize routing paths according to the topology change in mobile ad hoc networks. The existing work presented two self-adaptive on-demand geographic routing schemes to build efficient paths based on the needs of user applications and adapt to various scenarios for provide efficient and reliable routing. To overcome the impact due to inaccurate local topology knowledge, the topology information is updated at a node in the specific time periods. The on-demand routing mechanism reduces to control overhead made on geographic routing. The route optimization scheme adapts routing path according to the topology changes and actual data traffic requirements. Adaptive parameter setting scheme is introduced to allow each node to determine and adjust the protocol parameter values independently. However, existing work did not address resource parameters such as energy, bandwidth and data loss. The proposal presents and Integrated Resource Adaptive on Demand Geographic Routing (IRA-ODGR) for MANET. The node energy resource is optimized with path energy consumption rate and bandwidth utilization of the path is analysed. Loss rate is reduced in geographic routing with dynamic routes. The simulation conducted to demonstrate IRA-ODGR routing protocols.
