Abstract
Machine‐to‐machine (M2M) communication technology is an emerging technology that can connect smart wireless devices. The most obvious feature of M2M is that the communication between devices does not require human intervention. Therefore, ensuring the low‐energy consumption of M2M devices is a necessary condition for prolonging the survival time of their devices. This paper first considers the coexistence of M2M and H2H scenarios. Aimed at the energy efficiency of M2M equipment and the channel capacity of H2H equipment, a multiobjective problem is constructed for joint spectrum and power resource management, and a weighted Chebyshev algorithm is proposed to solve this problem. Secondly, in view of the additional interference problems caused by the introduction of M2M communication, the intercell cooperative link selection algorithm is used to optimize its resilience. The effectiveness of the algorithm is proven by simulation results.
Highlights
The development of wireless communication technology and people’s needs complement each other
When the demand factor p changes from 0.3 to 0.9, the energy efficiency of the normalized MTC equipment continues to increase. This is because the higher the weight factor of MTC devices, the higher their priority to obtain band resources
The channel capacity of the normalized HTC device decreases with the increase in P. This is because fewer subcarrier resources are allocated to HTC devices
Summary
The development of wireless communication technology and people’s needs complement each other. It can be applied to a variety of scenarios, such as intelligent transportation system, intelligent monitoring system, medical system, public security monitoring, and electronic meter reading [6] These application scenarios are composed of a large number of mobile devices, and different devices have different quality of service, which will cause huge traffic consumption. The research focus of HTC technology is mainly to improve the user’s transmission rate and reduce the delay, and the number of devices is far less than the number of M2M devices. When MTC devices and HTC devices coexist in the same cellular network and compete for spectrum resources together, the traditional communication quality between people will be affected by MTC. In the future 5G ultradense M2M scenario and the network where MTC and HTC coexist, how to ensure the performance of MTC equipment without affecting the performance of HTC equipment is an important problem to be solved at this stage [8]
