Paper Title
Study of MTCD Grouping and Resource Scheduling for Reducing Signal Load in LTE Network

This paper studies the load of control signal for machine type communication devices (MTCD) in long term evolution (LTE) network. Comparing to the traditional wireless communication services, internet of things (IoT) shall accommodate much more sensors or machine nodes and, therefore, introduce huge signaling load for radio resource management procedure. In order to reduce the signal overhead, the dynamic device grouping approach is proposed in this paper. Additionally, we also propose the residual radio resource allocation scheme based on the usage prediction. The purpose of the proposed grouping and allocation scheme is not only to reduce the number of control message generated but also to effectively utilize radio resource. According to the experimental results, the proposed device grouping and radio resource allocation scheme properly achieve the above objectives.
