We need to have an adaptive TCP protocol that can be tolerable on wireless network environement. TCP Westwood for use in the environe-ment that have a very high loss rate like a sattelite was proposed by modifying the existing bulk retransmission protocol. Bulk retransmission mechanism shows a highly enhanced performance on networks that have a very high loss rate but are prone to bursty loss networks. Also, it can exprience less performance on low late transmission environement. This paper proposes Adaptive Bulk Retransmission Mechanism that adjusts the number of bulk retransmitted packets based on the network conditions. The proposed mechanism was evaluated by using NS-2.
