Reducing Traffic Congestion for Machine to Machine Type Communication Over 4G-LTE Network by Decreasing Total Bytes Transmitted

摘要

In the near future, with the development of Machine to Machine (M2M) communication service providers may see a spike in traffic degrading the quality of service (QoS). With the addition of several M2M devices, it is expected to create conditions for overload in the Radio Access Network (RAN) and Core Network in 3GPP LTE networks. There are many studies that examine various characteristics of M2M communication devices including protecting the physical devices, authentication methods, congestion controls, privacy protection and many others. However, congestion will be a persistent problem with the increased devices and is the focus of this paper. There is research on the methods to control congestion, though this paper is considering increasing availability through reducing total bytes transmitted and thus avoiding or reducing overload and congestion in LTE network. In this paper, we have proposed and tested various optimizing mechanisms for reducing the signalling traffic and bandwidth utilization, thus decreasing the overload in the LTE architecture.
