Abstract

The invention relates to a reliable multi-path aggregation routing algorithm based on energy balance, and belongs to the technical field of a wireless sensor network. The algorithm comprises the following steps: analyzing a network data transmission feature, and establishing a multi-hop convergence network rate estimation model by combining the density and location information of the node; selecting more AMN and less AMNs at event regions with low energy consumption rate and high energy consumption rate by using a node selection algorithm based on the space relevancy; designing an optimal pathsearch algorithm based on a forwarding node set, and designing the multi-path convergence routing in energy balance by adopting the algorithm, wherein the multi-path convergence routing comprises anoptimal main path for data collection and an optimal convergence path for each AMN node, and all convergence paths are converged on an aggregation node on the main path; monitoring the data to arrivethe aggregation node through the convergence path, and enabling the data to arrive a Sink node through the main path after the aggregation node accomplishes the data aggregation. Through the algorithmdisclosed by the invention, the network energy consumption can be effectively balanced, the network life is prolonged, and the event detection reliability is improved.

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and relates to a wireless sensor network routing algorithm 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.

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.
