Abstract: The nodes in wireless network are mobile resulting in dynamic topology with high rate of link breakage and network partitions leading to interruptions in the ongoing communication in contrast to wired network. In the networks the link failure may be occurred due to a loss of energy in nodes, congestion, and power loss in nodes. Routing techniques help in path establishment for transmission. The existing routing protocols suffer from overhead causing energy loss which may be further aggravated by link failures. Different techniques can be used to prevent one path failure and this system uses multipath routing to overcome this issue. In this technique the system uses network coding protection for both single and multiple link failures. The system states that in connection each node receives a multiple copies of same data, first copy from the primary path and second copy from secondary path. In order to improve the performance, data is to be transmitted through the secondary path is compressed using Huffman coding in order to save the energy consumption. And encoding mechanism is used for providing security for the data transmitted between source to destination. This will ensure the recovery of data in failure of working path.
