Abstract

The invention discloses a method and equipment for relay node selection and power distribution in a wireless relay network. The method comprises the following steps of: obtaining the energy price of each node in the wireless relay network and the link information of a link between each node and adjacent nodes; respectively determining power distribution corresponding to the minimum target function value of the energy price of each node under the condition that the node is selected as a relay node according to the energy price and the link information of each node; and respectively determining the node and the power distribution corresponding to the minimum target function value for each node in power distribution as the relay node and the power distribution for data transmission. The communication equipment provided by the invention comprises an acquiring module, a first determining module and a second determining module. In the method and communication equipment provided by the invention, the pricing strategy of energy consumed by each node is introduced, so that the balance between energy utilization efficiency and energy consumption can be taken into account, and the service life of the wireless relay network can be prolonged.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and communication equipment for relay node selection and power allocation of a wireless relay network. Background technique [0002] Since the relay technology takes into account the characteristics of the two network architectures of the traditional cellular network and the decentralized peer-to-peer network, on the one hand, it can cover the users in the "blind spot" and "hot spot" areas of the cell through the relay, thereby reducing the Wireless transmission power improves the quality of received signals, thereby greatly improving network coverage and increasing channel capacity; on the other hand, compared with non-central distributed peer-to-peer network technology, it can stabilize the network structure, manage simply and effectively, and simplify protocol design. Therefore, the wireless relay network using the relay technology becomes the most promising wir...
