Performance Parameter Optimization for Congestion Control in MANET

Each network device has buffer for storing incoming packet if packet is not instantly transferred, store packets if buffer space is available and drop packets if buffer space is exhausted. Mobile ad hoc Network (MANET) devices also using buffer space for same purpose as other network devices. MANET has its own routing protocols which can compromised with frequent route exchange, dynamic topology, bandwidth constraint and multi hop routing. Efficiently managing buffer in devices is new area for research is called Active Queue Management. AQM manages queue according to queue policy for accepting incoming packets and forwarding received packets. To work in with congestion control there is FIFO and RED queuing techniques. In FIFO algorithm it wait for the first queue to finish and then get process to next step over. A Red queue work where number of data packet need to be hold and then process in the FIFO and required manner. In this paper our work is performed towards the congestion control protocol over the AODV DSR and DYMO protocol using RED algorithm.
