Abstract

In the existing system, the problem of TCP in MANET’s environment is packet losses induced by network congestion. In case if congestion occurs it leads to the loss of data. In the proposed system, Blue algorithm is used for avoiding packet loss in TCP with wireless network based on checking size of queue. If the size of queue is maximum, gateway directly forwards the packet to destination through queue. If the size of queue is minimum, gateway compresses the packet and forwards the packet to destination with notification. Thus source node efficiently sends packet to destination via gateway and queue. The destination sends the acknowledgement to source via gateway. Gateway checks the acknowledgement. If acknowledgement is positive, gateway removes the packet from backup or if the acknowledgement is negative, gateway retransmits the packet to destination.
