Topology control method for reducing inter-link interference

Abstract

The invention discloses a topology control method for reducing inter-link interference, which mainly solves the problem that the reduction of the inter-link interference cannot be guaranteed existing in the prior art. The implementation process of the method comprises the following steps: constructing a maximum power topology by a central control node; traversing all edges in an edge set of the maximum power topology by the central control node by taking the interference of the edge as standard, deleting and optimizing the edge set to construct an entire network topology; broadcasting entire network topology information by the central control node to all nodes in a network except for the central control node; determining logic neighbor nodes of all the nodes except for the central control node in the network by the nodes except for the central control node according to the received entire network topology information and adjusting the transmitting powers of the nodes. The topology control method has the advantages that the energy consumption of the node is reduced and the inter-link interference is reduced, and can be used for a wireless sensing network.

Problems solved by technology

When studying the channel assignment or scheduling problem based on the underlying topology, it is necessary to consider the interference caused by a pair of nodes to the link that can communicate within the transmission range during the communication process, and the above two types of algorithms cannot guarantee that the link can be reduced. Interference between, and thus can not provide a good underlying topology
