Abstract

The invention provides a routing protocol with high-efficient energy based on multiple mobile aggregation nodes. A plurality of mobile aggregation nodes are deployed in a perception area of a wireless sensor network, and each mobile aggregation node is a cluster head and is used to form a plurality of clusters. Each mobile aggregation node can carry out autonomous movement and can communicate with each other. A current sensor node firstly determines a distance between the node itself and the mobile aggregation node, and if the distance is less than a transmission radius, the current sensor node directly communicates with the mobile aggregation node. Otherwise, a maximum optimal hop count of the current sensor node to the mobile aggregation node and a maximum distance between the current sensor node and a next hop of a sensor node are calculated so as to find an optimum next hop of the sensor node. In the invention, defects of an energy cavity phenomenon and uneven distribution of cluster heads are avoided, a network flow load is mitigated and a life cycle of a wireless sensor network is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a method for transmitting data in a wireless sensor network. Background technique [0002] A wireless sensor network is usually composed of a large number of small and low-cost sensors, and the sensor nodes send the collected information to the sink node through a single-hop or multi-hop mode. These sensor nodes themselves have computing power, storage capacity and communication capacity. Since WSN does not need the support of fixed network infrastructure, it has the advantages of easy rapid deployment, easy expansion, strong resistance to destruction, and suitable for harsh environments. Many fields have important research significance and broad application prospects. [0003] Due to the small size of the sensor nodes, the calculation, storage and communication capabilities of the nodes are limited; in particular, the sensor nodes are generally pow...
