ABSTRACT
Due to the dynamic topology, self-configuration and decentralized nature of Mobile Ad hoc Network
(MANET), it provides many benefits in wireless networks and is easy to deploy. But the transmission of
data over ad hoc networks has elevated many technical issues for successful routing. Congestion is one of
the important issues which cause performance degradation of a network, due to long delay and high packet
loss. This paper proposes a Congestion aware Link Cost Routing for MANET where the protocol finds a
path with optimized linked cost based on SNR, Link delay, and the and remaining battery power. Along
with this optimization, in this protocol, every node finds its congestion status and participates in the route
discovery on the basis of its status. Data forwarding is also done based on the congestion status at the time
of forwarding. The protocol results in better performance in terms of packet delivery fraction, end to end
delay, throughput, and packet drop when compared to existing protocols.
