ABSTRACT

Congestion control in wireless ad-hoc networks is a genuine problem. In this thesis, the two routing protocols for congestion control are calculated. The measures to decrease the collision problem arc described wit h special congest ion control routing protocols. After the comparison between AODY and R-AODY with the help of some congest ion control mechanism, it is found that AODY works on a simple algorithm which is not sufficient to control the congestion in ad hoc network. On the other hand R-J\ODV uses drop factor techniques which drop the extra packets on the network and also decreases the congest ion
on heavy traffic load. However, R-AODV works better on heavy traffic as compared to
AODY. Apart from this, R-J\ODY 's performance is not affected y the quantity of mobile nodes and data rate. Additionally, my results show that when RAODY is compared with
/\ODY method , its delay per packet decreases hut the quantity of packet delivery ratio increases.
