Abstract: Many of current P2P application tend to use UDP as their transport protocol. Since UDP does not provide congestion control mechanism, the developers of these applications have to decide how frequently to send UDP packet individually. It is necessary to provide a common congestion control protocol specially design for P2P networks. This paper proposes a protocol for such propose and use simulation to valid it

Abstract: Congestion in wireless sensor networks can affect the networks performance seriously,not only it has impact on data transmission and the quality of service, but also wastes energy and shortens the network lifetime. Aiming at this issue, this paper proposed a cross-layer congestion control algorithm based on traffic prediction (CCATP), it can take congestion mitigation measures in advance according to the prediction result. CCATP comprises three mechanisms: (i) congestion prediction; (ii) local congestion control mechanism based on backoff time adjustment; (iii) transmission route selection based global congestion control mechanism; Simulation experiment results show that CCATP can reduce the packet loss number and improve the energy efficiency significantly, so as to effectively improve the service performance of network.

Abstract: Standard TCP has lots of problems; for example, the network bandwidth can not give its full play in certain application conditions such as high speed or long distance. High Speed TCP (HSTCP) can solve these problems, but it has serious problems in the fairness of different RTT. Based on the analysis of HSTCP fairness, an algorithm of adding fair factors to improve fairness of HSTCP has been put forward after fairness simulation test by NS2. NS2 simulation experiments prove that this algorithm has greatly reduced the unfairness because of the different RTT.

Abstract: Multipath Transmission Control Protocol (MPTCP) is proposed by the IETF working group in 2009, can provide end-to-end multi-channel communication, can greatly increase the utilization of network resources and reliability. The study of the details is underway. Congestion control is one of the main issues in MPTCP study. Its goal is to ensure network throughput, to ensure the fairness of the network and to balance congestion .So this paper mainly studies congestion control algorithm. In terms of resource pooling, we propose a MPTCP congestion control algorithm based on packet loss. The algorithm can guarantee the network throughput and improve the fairness among users ,at the same time, the algorithm greatly achieve resource pooling.

Abstract: The traditional congestion control mechanism of transport control protocol (TCP) has been proved cannot satisfy the wireless scenario. The extensive research has been done to understand the drawback of TCP in wireless networks. In this paper, we proposed a new congestion control algorithms for mobile ad-hoc networks (MANET) at the TCP sender side which efficiently adapts to the maximum transmission rate of a mobile wireless link, the new algorithms follow the idea of FAST TCP which uses delay as congestion measure. However, FAST TCP has limitations when used over a dynamic mobile wireless link with a high frame error ratio (FER) and frequent delay changes due to the variable rate. The new algorithms overcome this shortcoming by improving the congestion signal choice. By using analysis, we proved that the new congestion control mechanism provides superior performance over mobile wireless network environments.

Abstract: Congestion is an important issue in the research of end-to-end congestion control. The congestion issue in transmission with TCP is studied. Under the situation of different round trip time and multiple congested gateways, ECC (Explicit Congestion Control) algorithm is proposed to solve the congestion problem of TCP. The basic idea is to explicitly improve Congestion by adding mechanism at both end systems and gateways. Then study the tile congestion of Internet data transmission. Internet data transmission relies on end system mechanisms to keep Congestion. As the number of the users has been very large, this scheme has become vulnerable. It is required to deploy some congestion mechanism at gateways.
