Study on Different Transmission Control Protocols Used in Wireless Networks

Transmission control is an important issue for supporting Quality of Services (QoS) in Wireless Sensor Networks (WSNs). This chapter gives an introduction to the transmission control relevant protocols and algorithms, often developed for particular applications to reflect the application-specific requirements. According to the functionality, the existing works can be categorized into three main types: congestion control, reliability guarantee and fairness guarantee. Due to the unique constraints of WSNs, these transmission control protocols are not “cleanly” placed on top of the network layer, but call for careful cross-layer design. In the end, some exciting open issues are presented in order to stimulate more research interest in this largely unexplored area.

Testing And Evaluation

Datacenter is the important infrastructure to provide resource and service in Internet. Due to the widely observed congestion, all kinds of transmission control mechanisms have been proposed to satisfy diverse network performance demands. Based on InfiniBand (IB) which is widely applied for datacenter construction, this paper proposed a generic testing and evaluation platform IBperf to verify transmission control protocols. We designed a central controller to instruct distributed clients to generate different communication patterns and execute commands of the protocol. The transmission performance can be derived based on the captured packets and digest. In the experiment, IB congestion control (CC) was evaluated through IBperf on our real IB platform. IBperf showed the improvement of fairness and throughput with low overhead based on CC mechanism. It proved IBperf to be an effective tool for the evaluation of IB datacenter.

Different Characteristics

Multipath Transmission Control Protocol (MPTCP) is an extension of TCP meant for multihomed devices, which uses all the available interfaces for a single connection. MPTCP was evolved for Bandwidth aggregation and re silence to network failure. The wireless networks of multihomed devices are of different characteristics, when used together decreases Quality of Service (QoS). MPTCP schedulers tried to fill this gap with different approaches. In this paper we tried to study these schedulers in different network scenarios and came with the findings that to achieve good throughput and decrease download time, only fast paths are preferred.
