Abstract

The invention discloses a wireless sensor network topology resource allocation method and device. A sensor node set and a aggregation node set of a bipartite graph modeled wireless sensor network andthe communication connection relationship between the sensor node set and the aggregation node set are used to realize the sampling and allocation of the sensor nodes and the communication link resources in the wireless sensor network topology under the condition of maintaining the stability of important topological attributes and satisfying the types and quantities of the sensor nodes required bythe user through the bipartite graph sampling technology. The invention can accurately allocate the number of the sensor nodes and the corresponding data communication link resources required by theuser according to the type and quantity of the sensor nodes required by the user under the condition that the topological attributes of the wireless sensor network bipartite graph are stable and constant.

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...
