This paper is based upon the concept of improving the novel congestion control scheme in Wireless Sensor Network. In WSN Congestion is an important issue. Congestion occurs at the transport layer of the OSI model. The Novel Congestion Control Scheme proposed a rate-based Fairness-Aware Congestion Control Protocol (FACC), which controls congestion and achieves approximately fair bandwidth allocation for different flows. Congestion occurs at the intermediate nodes in WSN. This means the time during when intermediate nodes send Flow Control Acknowledgement to Source Node to describe the congestion status so as to control its flow rate will result in large amount of packet loss. This motivates the need of new technique to control the packet dropping at the intermediate nodes. So to avoid the packet dropping the proposed work introduced the Improved Novel Routing Algorithm (INOVEL) for Congestion Control in Wireless Sensor Network which works in three phases. These three phases plays an important role in utilizing the available free spaces of the neighbored nodes and free routing paths to accommodate the load of Congestion Affected Node's. This Routing Algorithm is implemented in NS-2 where the results show that such an algorithm improves the performance, efficiency of the network by decreasing end to end delay and increasing both the throughput and packet delivery fraction among the nodes.
