Abstract:
Satellite communications is one of the wireless communication technologies, which is widely spread all over the world. Vegas is a kind of the Transmission Control Protocols (TCPs) over satellite communications. However, there are some shortcomings with this protocol, such as being less aggressive and unfair. These would penalize its performance over satellite communications to a certain extent by taking into account the long round trip time and high packet error rates. In this paper, an adaptive end-to-end congestion control algorithm (Vegas-L) is proposed to overcome these issues. Vegas-L can take full advantage of the historical information of network to divide network conditions into more detailed states, then carry out some adaptive and reasonable adjustments according to the specific network state. Simulation results show that Vegas-L is not only able to improve the aggressiveness to gain high throughput but also has the ability to enhance its fairness over satellite networks.
