Analysis and improvement of TCP fairness across mobile ad hoc networks and Internet
Meilin Shi · Journal of Communications · 2007
The behavior and reason of the TCP unfairness in Internet-connected mobile ad hoc networks based on IEEE 802.11 MAC were exposed through simulations and analysis.The concept of TCP fairness in hybrid environment was de-fined basing on the bandwidth occupation from the gateway,and an adaptive gateway bandwidth control scheme TCP-GAFC was proposed to solve the unfairness problem.TCP-GAFC only needs to be implemented in the gateways without modifying the TCP or MAC protocol.It has good applicability and scalability.The simulation results show that TCP-GAFC can significantly improve the TCP fairness,and can achieve reasonable throughput.
