Methods and Mechanisms on Transmission Control for M2M Communications
Wang Qu · 2013
M2Mcommunications are important parts of the Internet of Things(IoT).Among them,the IP-based M2M communications achieve a unified addressing,coordinated and unified management for nodes,is also a hot research topic for many years.In traditional TCP error control mechanism,the loss of data is simply as network congestion,and congestion control mechanisms are used to solve these problems.The traditional TCP ignores wireless link imperfections including high bist error rate,frequent topology changes,channel asymmetry,unfairness of MAC protocol and so on.Therefore,the traditional TCP is not suitable for secure M2Mcommunications.This paper analyzed the TCP deficiencies and corresponding improving methods that impact the M2Mcommunications,and discussed the appropriate solution respectively from end to end connections,split connections and mixed connections.Finally,the paper proposed TCP improving thinking and research directions for M2Mcommunications.
