Relay arrangement method of multi-hop wireless chargeable sensor network based on clustering theory

Abstract

The invention relates to a relay arrangement method of a multi-hop wireless chargeable sensor network based on clustering theory. The method comprises the following steps: firstly arranging an environment for relays of the multi-hop wireless chargeable sensor network; and then determining relay node number according to the coverage probability of the network; selecting an initial location of the relay based on the degree of the sensor node, and then performing classification according to the Euclidean distance between the relay and the sensor node by using a clustering algorithm, and acquiringa new relay location by computing the category centroid of each classification, orderly iterating until the algorithm is convergent, thereby optimizing the location of the relay node, wherein the charging trolley charges the sensor node requesting the charging through an online charging way. By using the arrangement method disclosed by the invention, the relay number can be reasonably determined,and the arrangement of the relays can be optimized, the charging distance between a charging device and the sensor node under the multi-hop wireless charging environment can be effectively prolonged,the time delay of waiting for charging by the node is reduced, and the energy supplementary efficiency of the network is generally improved.
