Abstract

The invention relates to a reliable multipath aggregation routing algorithm based on energy balance, and belongs to the technical field of wireless sensor networks. The algorithm includes: analyzing the characteristics of network data transmission, combining the density and location information of nodes, establishing a multi-hop aggregation network energy consumption rate estimation model; Select more AMNs and fewer AMNs in the area; design an optimal path search algorithm based on forward forwarding node sets, and use this algorithm to design energy-balanced multi-path aggregation routes, including an optimal main path for data collection and each The optimal aggregation path of AMN nodes, all the aggregation paths converge on the aggregation node on the main path; the monitoring data reaches the aggregation node through the aggregation path, and after the aggregation node completes the data aggregation, it reaches the Sink node through the main path. The invention can effectively balance the energy consumption of the network, prolong the service life of the network and improve the reliability of event detection.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and relates to a wireless sensor network routing method with reliable detection and high energy efficiency. Background technique [0002] Sensor nodes in wireless sensor networks are generally powered by batteries, and are usually deployed in harsh environments or unattended monitoring areas. It is very difficult to charge nodes or replace batteries, and their energy resources are severely limited. Therefore, energy utilization efficiency and network life are very important. Important performance indicators of wireless sensor networks. In addition, sensor nodes are usually used to monitor events, and sink nodes complete event detection by processing data collected by sensor nodes, so event detection reliability is also an important performance indicator of wireless sensor networks. [0003] Compared with the active mode, the energy consumption of the sensor nodes in the sleep mo...

AI Technical Summary

Problems solved by technology

On the premise of ensuring the reliability index of network detection, selecting fewer active monitoring nodes can reduce network energy consumption and prolong network life, but the detection quality will also decrease

And more monitoring nodes mean more energy consumption, which will reduce the network lifetime

At present, there are few methods that take into account both network energy efficiency and detection reliability.
