TCP SACK and TCP Vegas Performance in Wireless Ad Hoc Networks

Simulation method is employed to analyze the performance of TCP SACK and Vegas in wireless ad noc networks. An improved Adapted SACK option format(ASACK)and a new technique named RTT Notification (RN) are used to improve the performance of TCP Reno and Vegas in wireless ad hoc networks respectively.Associativity-Based Routing(ABR) protocol is also implemented to investigate how the stability of routes affects the performance of TCP Vegas.
