The wide deployment of Wireless network has increased the network traffic. Long congestion and frequent link failures in wireless network lead to more number of packets being dropped and incur high end-to-end delay, thereby degrading the overall performance of the network. For solving the issue of congestion in Wireless network, congestion controlled the adaptive routing mechanism is proposed. The proposed work has three phases namely congestion detection, alternative path computation and Fast retransmit and fast recovery the packets on a new path. Congestion control is mainly incorporated at the transport layer. Congestion in the path can be detected based on the free space available in the buffer. To identify multipath routing and load aware of each node to minimize the data drop but all given approach are using routing base congestion control. Different approaches to congestion avoidance have been introduced in the past few years. The traditional flooding and gossiping algorithm can cause loss of data. Random Early Detection (RED) is an alternative way to reduce packet loss as congestion measure. Instead of dropping only at a full buffer, RED maintains an exponentially weighted-queue length and drops packets with a probability. If the weighted queue length is less than a minimum threshold no arrival packets are dropped. When it exceeds a maximum threshold all packets are dropped. When it is in between minimum and maximum threshold a packet is dropped with a probability that is piecewise linear and increasing function of the CR (Congestion resistant) algorithm. This algorithm will find another way to send the packets and to maintain that, this way is shortest safe way and controls congestion.
