Embodiment Construction

[0044] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] The present invention optimizes the overall structure of the RFID sensor network by using a computational intelligence algorithm, and adopts a coding method based on random ranking (Random Ranking) to avoid the generation of a ring structure. Better design results than traditional methods can be obtained in a shorter computing time.

Abstract

The invention discloses a deploying method of an RFID sensor network. The deploying method of the RFID sensor network comprises the following steps of S1, obtaining the sum N of RFID sensing nodes and setting total iterations A; S2, deploying evolution population including / ps / individuals; S3, calculating a fitness function value of each individual; S4, updating an iteration counter and judging whether k is smaller than A or not; S5 selecting and using the individuals with minimum fitness function values as optimal individuals and deploying the RFID sensor network according to the optimal individuals. The deploying method of the RFID sensor network has the advantages that the network deploying process is simple and quick, a tree topology structure can be directly formed, operation pressure brought by annular channels in each-time searching is avoided, and computation complexity of the method is remarkably lower than that of an existing heuristic design method.

Description

technical field [0001] The invention relates to the application field of radio frequency identification, in particular to a deployment method of an RFID sensor network. Background technique [0002] Radio Frequency Identification (RFID) is a near-field wireless communication technology. The reading and writing of specific target information can be realized through the electromagnetic field interaction between the radio frequency tag and the identification system (reader). Combining RFID with wireless routers or wireless receivers (Access Point, AP) to form sensing nodes to construct sensor network systems is one of the main directions of its development. It can be used in the Internet of Things, smart home, logistics tracking and other fields, and has important social and economic value. [0003] RFID sensor networks often use a centerless multi-hop architecture to achieve data communication based on signal forwarding between nodes, which can effectively improve the robust...
