Performance Improvement of TCP Based on Routing Protocol in Multi-hop Ad hoc Networks
Zhang Li-jun · Journal of Nanjing Institute of Posts and Telecommunications · 2005
In multi-hop Ad hoc network based on IEEE 802.11,Frequent collision in MAC layer influences TCP performance.In order to improve the successful probability of TCP data transmission,this paper proposes a scheme relying on the routing protocol to keep TCP unaware of the short and frequent interruption of the low layers.With the new scheme,the simulation results show that TCP drop rate was reduced by a large margin,and that TCP throughput was increased about 12%-200%.
