Embodiment Construction

[0055] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] figure 1 It is a schematic diagram of the reliable multipath aggregation routing algorithm based on energy balance in the present invention. Such as figure 1 As shown, when an event occurs, the algorithm first uses the multi-hop aggregation network energy consumption rate estimation model to estimate the energy consumption rate of the event domain, and assigns the corresponding number of AMNs to the event domain according to the energy consumption rate; The node selection algorithm selects the corresponding number of AMNs in the event domain; then, the remaining energy of the path nodes, the path energy consumption, and the number of path hops are integrated, and the optimal path search algorithm based on the forward forwarding node set is used to design an energy-balanced multi-path aggregation route. , the route includes an optim...

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.

Description

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. [0003] Compared with the active mode, the energy consumption of the sensor nodes in the sleep...
