This paper introduces a new type of digital and energy integrated wireless communication network, which integrates the independent wireless
information transmission and wireless energy transmission in the traditional
wireless network, and realizes the cooperation and simultaneous transmission
of data and energy. The traditional wireless energy communication focuses on
the physical layer, but the digital energy integrated network proposed in this
paper emphasizes systematicness, and the corresponding protocols and resource
allocation are designed and implemented at each layer of the network. Unlike
other renewable energy sources such as wind and solar power, the power source
in DEINS, namely the radio frequency (RF) signal from the base station, is not
affected by the natural environment and is completely controllable. Digital and
energy integration network has great potential in solving the energy efficiency
problem of wireless communication system and realizing the energy saving
and emission reduction of wireless communication. In this paper, the proposed
digital energy integration network is described from two aspects: energy and
network. In terms of energy, this paper introduces and analyzes the energy
coding, energy model and energy management of digital energy integrated
network. In terms of data network, several core technologies, including physical
layer, data link layer protocol and joint resource allocation, network layer and
typical network application scenarios of digital energy integrated network, are
discussed in each layer of log-energy integrated network. In the introduction
of each layer, this paper focuses on the discussion of new directions rather than
a simple restatement of existing research work. Finally, this paper summarizes
and forecasts the development trend and research direction of this field in the
future.
