Adaptive multi-path routing for congestion control

Routing of data packets from source to destination is the primary function of Network layer. If a single path is chosen for data transfer from source to destination, congestion and packet transfer delay increases. In order to minimize this problem, multi-path routing protocol is preferred. There are many multipath routing techniques available; such as SMPC, SMPC-I, SMPC-P. In multi-path routing, not all the paths may have the same capacity, and then there is every possibility of occurrence of congestion at a router in the path. The proposed method provides a better solution for minimizing the congestion by rerouting the data packets over other paths, which are not utilized by the same in multi-path routing. This method avoids the unnecessary dropping of packets at a congested router and improves the network performance.
