Abstract

The invention discloses a wireless sensor network topology resource allocation method and device, using a bipartite graph to model the sensor node set, the convergence node set and the communication connection relationship between them, and through the bipartite graph sampling technology, in the Under the conditions of maintaining the stability of important topology attributes and satisfying the types and quantities of sensor nodes required by users, the sampling and allocation of sensor nodes and their communication link resources in the topology of wireless sensor networks can be realized. The present invention can be based on the types and quantities of sensor nodes required by users , under the condition of keeping the topological properties of the wireless sensor network bipartite graph stable, accurately allocate the number of sensor nodes and corresponding data communication link resources for users.

Description

technical field [0001] The invention relates to the field of wireless sensor network topology control, in particular to a wireless sensor network topology resource allocation method and device. Background technique [0002] Wireless sensor network topology control consists of two parts, namely topology construction and topology maintenance. Once the initial network optimization topology is established, the network begins to perform its assigned tasks. First, there is a topology initialization phase for all wireless sensor networks. At this stage, each node transmits with its maximum transmit power to establish the initial topology. After the initialization phase, the initial topology is optimized by running different algorithms or protocols, and finally an optimized topology is constructed, which is called topology construction. Once the topology construction phase has established an optimized network topology, the topology maintenance phase must start working. In the to...
