The DSR reduces the Data loss and Latency time, while data transmission through the network.
Every Node (System) in the network should have the information about the neighboring Nodes.
The Node automatically handles the Cache Updation Process if any Link failure is happened in the Network.
TCP performance degrades significantly in Mobile Ad hoc Networks due to the packet losses.
Most of these packet losses result from the Route failures due to network mobility.
TCP assumes such losses occur because of congestion.
It applies various techniques to control the congestion.
It mainly concentrates on the route failures in the network
It is proactively disseminating the broken link information to the nodes that have that link in their caches.
It defines a new cache structure called a cache table and present a distributed cache update algorithm.
Each node maintains the information necessary for cache updates in its cache table.
