Routing method with balanced energy consumption

Abstract

The invention belongs to a routing method capable of realizing the balanced energy consumption by virtue of a mixed potential energy field in the technical field of wireless sensor networks. The routing method comprises the steps of initializing a network, sending a sink node depth value, updating and sending a first skip node depth value, updating a routing list, determining current parameter information of each node in a second skip, determining and updating residual energy of each node, determining and updating an energy density value of each node, processing data packets generated and received by the nodes, determining candidate nodes a next skip, determining a mixed potential energy field value of each candidate node in the next skip, and determining a first-choice node in the next skip and a next skip node. According to the method, the candidate nodes of the next skip nodes are screened out firstly, and then the first-choice node and the skip jump node are screened out from the candidate nodes. The routing method has the characteristics that the network load is uniform, the energy consumption of each node is balanced, a untimely blind zone of the network is avoided, the service life of energy sources is prolonged, the network operation reliability is improved effectively, benefits are increased effectively, the network operation cost is reduced, and the like.

Problems solved by technology

[0015] Although this routing method overcomes the disadvantages of many energy efficient routing methods, such as premature failure due to unbalanced energy consumption in the network, it not only considers the node depth value, but also the node energy density value and Therefore, this method will not only cause data packets to be transmitted later, but also may cause routing loops and redundant hops, which will cause transmission delays and unnecessary energy consumption, restricting the effective transmission of data packets. Defects that affect the smooth and efficient operation of the network, and even cannot ensure that the data packets are finally transmitted to the sink node
