The invention relates to a time-delay constrained wireless sensor network routing implementation method based on a fuzzy gradient. The method comprises a proximate Sink node selection implementation step and a gradient fuzzy classification implementation step. In the method, aiming at limited time-delay constrained energy of a wireless sensor network, each sense node transmits a data packet to anadjacent node along the Sink direction of the base station until data reaches a Sink; and a condition that certain nodes are used up prematurely and a large amount of surplus energies are left in other sensor nodes often occurs in the sensor network, thus the routing of the nodes is focused, and the energy consumption of each node is balanced, thereby effectively improving the network energy consumption efficiency and prolonging the network survival time.
Description
Delay Constrained Fuzzy Gradient Based Routing Method for Wireless Sensor Networks technical field The invention belongs to the technical field of wireless sensor networks, in particular to a fuzzy gradient-based wireless sensor network routing method with delay constraints. Background technique With the deepening of wireless sensor network research, the wireless sensor network system has gradually entered the practical stage, so there are requirements for visualization, diversification, and fine-grained environmental detection results, and the wireless sensor network that guarantees the quality of service QoS is an important research direction. And with the increase of network scale and complexity, the single sink network architecture can no longer meet the system requirements. For a system with two or more sink nodes, the data collected by the node is sent to the nearest sink node through different paths, and one data can be collected through multiple sinks at the same ...
