Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] figure 1 The method of the entropy-based wireless sensor network QOS routing algorithm provided by the implementation of the present invention in a dynamic water environment is shown, and the method includes:

[0045] In step S101, first divide the information collection area into a network, and after the division, the Sink node broadcasts all the information, so that each node knows the grid and location it takes;

[0046] Under the influence of water flow, the WSN nodes are in an unstable state, so the location calculation of the nodes needs to be carried out continuously. To facilitate ...

Abstract

The invention discloses a determination method of a QOS (quality of service) route longevity path of a wireless sensor network in water environment. The determination method comprises the following steps of: firstly, carrying out a network split on an information acquisition region, enabling a Sink node to broadcast all the information after split, and enabling each node to know the taken framework and position; then, carrying out distributed arithmetic on each framework, seeking one or more than one shortest framework path from each framework to the Sink node, and enabling only can two adjacent frameworks transmit data, so as to ensure that the network transmission energy consumption is least when the network is in normal operation; and finally, seeking a suitable path based on an entropy idea, utilizing the entropy to carry out auto patching on the path after operation for a certain time, namely, achieving the self-healing of the structure of the whole network route after the node is vitiate. Compared with algorithms such as Long-term, DBR, DTN(delay / disruption tolerant network), the QOS route algorithm has better properties on the aspects of route reconstruction times, route success rate, network energy consumption and network delay.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a method for determining a QOS route long-lived path of a wireless sensor network in a water environment. Background technique [0002] Sensors integrating sensing, data processing, positioning and wireless communication functions have broad application prospects in many aspects such as environmental and military monitoring, earthquake and climate prediction, underground, deep water and outer space exploration, while the external environment is uncertain Sexuality often results in the need to deploy hundreds or thousands of such sensors to work together. Therefore, the research on the sensor network (Sensor Network) composed of large-scale sensors (sensing nodes) is attracting extensive attention of researchers, and the research on terrestrial wireless sensor network has been developed rapidly. As people pay more and more attention to the water envir...
