Abstract

The invention belongs to the technical field of wireless resource allocation, and discloses a topology control method with high energy efficiency. The topology control method comprises the steps of firstly loading network parameters, and determining a performance objective of the network; establishing a neighbor list of each node in the wireless Ad Hoc network; calculating the optimal power of each node according to the performance objective of the network; and constructing a network topology structure with the optimal node degree according to the optimal power of each node. The topology control method can be used for optimizing the large-scale wireless Ad Hoc network, and enables the network to have the advantages of high energy efficiency and optimal connectivity at the same time. The innovation of the invention lies in that both the energy consumption and the connectivity of the network are taken into consideration, and a topology control method capable of improving the energy efficiency and communication efficiency of the network is proposed.

Description

technical field [0001] The invention belongs to the technical field of wireless resource allocation, and in particular relates to an energy-efficient topology control method Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: In a wireless Ad Hoc network, the topology of the wireless Ad Hoc network describes the connectivity information of the entire network, including node information in the network and connection conditions between nodes. Topology control refers to the construction of network topology by adjusting the transmit power of nodes with the goal of high energy efficiency and connectivity when network resources are generally limited. Topology control technology is a key technology to improve network energy efficiency. By adjusting the transmit power of nodes, the purpose of optimizing network performance is achieved. Aiming at the problem of low energy consumption, N.Li proposed a topology control met...
