The wireless sensor network based on the low-power consumption lossy network routing protocol comprises sensor nodes and a gateway node. On the basis of the existing protocol, the remaining energy of the current node is measured through an energy supply and evaluation module, a phenomenon of bearing heavy forwarding and transmission tasks when the current energy is over low can be avoided, and network energy consumption of the same node is avoided. nodes in the network are layered, a certain sink node is selected to fuse data information and then transmit the data information, repeated data transmission is avoided, and the wireless sensor network efficiency is improved.

Description

technical field [0001] The invention relates to a wireless sensor network for smart homes, in particular to a wireless sensor network based on a low-power lossy network routing protocol and a calculation method thereof. Background technique [0002] Wireless sensor networks have the characteristics of limited node energy, large-scale deployment, data-centricity, and dynamic topology. In order to meet application requirements, it is often necessary to deploy a large number of nodes in the monitoring area to obtain accurate data. When the network scale is large, it is necessary to consider the fault tolerance, stability and scalability of the network; unlike the traditional address-centric network, the wireless sensor network uses data as the center for query or transmission; node exit and new join, Therefore, routing must be able to establish and maintain a dynamic topology. In wireless sensor networks, due to energy constraints, nodes often cannot communicate directly. When...

Problems solved by technology

Due to the limited storage capacity, communication capacity and energy of sensor nodes, the design goal of traditional wireless sensor network routing protocols is often to simplify the protocol algorithm and save energy consumption, which makes the scalability of the network poor.

However, with the development of wireless sensor networks, the application scenarios are becoming more and more complex. In large-scale networks, maintaining network stability, reducing node energy consumption and good scalability have become the main challenges in designing routing protocols.
