Resource allocation method for small energy harvesting base stations based on coalition game

Abstract

The invention discloses a resource allocation method for small energy harvesting base stations based on a coalition game. The method is characterized in that a model of the small energy harvesting base stations is first constructed, wherein the neighboring small base stations are connected through transmission lines for information exchange and energy transfer; and the non-overlapping coalition game is then established for the problems of energy sharing and time allocation of the small base stations, wherein the small base stations with the energy harvesting capability serve as game participators, strategies serve as coalitions that the small base stations join, a utility function of each small base station is defined as the spectrum efficiency of the small base station for information transmission within a period allocated in the coalition that the small base station joins, and the utility of each coalition is the sum of the utilities of the small base stations joining the coalition.The method adopting the technical scheme has the advantages that the information exchange and energy sharing can be achieved through the transmission lines; and the small base stations joining the same coalition can share transmission times and harvested energy, and the small base stations meeting transfer conditions can transfer among the coalitions, so that the benefits of the corresponding small base stations and the total benefits of the corresponding coalitions can be improved, and the maximum system utility can be achieved.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an energy collection small base station resource allocation method based on alliance game. Background technique [0002] Since the wireless communication system can provide communication services for mobile devices, it is especially suitable for scenarios where the terrain is relatively difficult to lay lines. On the one hand, in order to achieve the goal of providing services for mobile users in a green and energy-saving manner, energy harvesting base stations have always been a hot research point in the field of communication. On the other hand, with the advent of the 5G era, in order to achieve all-round coverage, dense small base station networking is also an area worthy of investment. Due to the scarcity of spectrum resources, spectrum multiplexing technology will be used in dense small base station networks. The problem brought by this method is that it causes interfer...
