Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with the simulation experiments of examples and the accompanying drawings.

[0034] Such as figure 1 As shown, the application scenario of the present invention embedding the energy-efficient transmission power and transmission time slot allocation scheme in the M2M cellular network is: a small-scale M2M cellular network application environment such as home or office, and does not need to set up new network infrastructure (such as MCG) , replace MCG with H2H terminals with stronger computing power, larger storage space, and easier charging, and realize the M2M communication mode in the cellular network.

[0035] The energy-efficient transmission power and transmission time slot allocation method embedded in the M2M cellular network of the present invention consists of a base station BS, a H2H ter...

Abstract

A high-energy-efficiency power and time slot distribution method in an embedded M2M cellular network is suitable for being used in small-scale wireless network communication of household or an office and the like. A base station BS, a H2H terminal and a plurality of M2M terminals are used to carry out networking. The M2M terminals feed residual energy information back to the H2H terminal. The H2H terminal calculates a time slot number and a distribution parameter of the M2M terminals which carry out networking with the H2H terminal and feeds back to the M2M terminals. The M2M terminals calculate optimal data transmission time and optimal emission power during communication according to received information so that energy consumption of the M2M terminals is effectively reduced. A power and time slot distribution flow is ended till that energy of one M2M terminal is exhausted. The method is simple. Whole network M2M terminal energy consumption is effectively reduced and balanced so that a purpose of prolonging a M2M terminal group network lifetime is reached.

Description

technical field [0001] The present invention relates to a transmission power and transmission time slot allocation method, and is especially suitable for an energy-efficient power and time slot allocation method in a cellular network embedded in M2M used in small-scale wireless network communications such as homes or offices Background technique [0002] With the rapid development of the next-generation 5G (Five Generation) cellular mobile communication technology, the M2M communication mode based on the cellular network has become a key technical component to realize the "Internet of Things". Traditional Human-to-Human (H2H) mobile data services (such as mobile multimedia data download) are often characterized by long time, large data volume, and burst transmission. Different from H2H data services, M2M data services mostly have the characteristics of non-mobility, small scale, low frequency, and periodic transmission, and require group supervision and scheduling for multip...
