摘要
An improved selective acknowledge algorithm is proposed to replace cumulative acknowledge algorithm to solve the "gap" problem in TCP receiver's window caused by high packet loss rate and link re-establishment of mobile ad hoc networks. TCP throughput performance of different TCP variants are compared and analyzed in details by simulations both under static chain topology and under dynamic network topology of mobile ad hoc networks. Simulations also show that the improved algorithm can improve TCP performance in mobile ad hoc networks considerably and leave more reservation space of TCP option for future use.
