Wireless sensor network-based route establishing method and device

Abstract

The invention discloses a wireless sensor network-based route establishing method and a wireless sensor network-based route establishing device, and is used for solving the problem that related information of the MSN in the current area cannot be acquired in real time, so a Microsoft service network (MSN) is moved to a new area currently before a route is successfully established or when the route is just established to cause a condition that data cannot be routed to the MSN during data transmission on the established route in the route establishing method in the prior art. The method comprises the following steps of: determining a first wireless sensor node corresponding to a signal which is detected by a mobile terminal currently and has the signal intensity greater than the preset intensity threshold value; determining a second wireless sensor node capable of establishing a route with the mobile terminal currently according to the first wireless sensor node and the current network topology information of the mobile terminal in the wireless sensor network; and establishing the route between the mobile terminal and the second wireless sensor node.

Description

technical field [0001] The invention relates to the technical field of sensors and communication, in particular to a method and device for establishing a route based on a wireless sensor network. Background technique [0002] In recent years, with the rapid development of microelectronics technology, micro-electro-mechanical systems (MEMS, Micro-Electro-Mechanical Systems) technology and wireless communication technology, the design and application of low-power wireless sensors integrating sensing and wireless communication functions become a reality, the resulting wireless sensor network has a huge application prospect in medical treatment, public security, military and environmental monitoring and so on. [0003] In a wireless sensor network, there are generally two types of nodes, one is a wireless sensor node (Sensor Node), which is equipped with various types of sensors, and the surrounding environment is detected and sensed through these sensors; the other is a wireles...

AI Technical Summary

Problems solved by technology

[0006] The embodiment of the present invention provides a wireless sensor network-based route establishment method and device to solve the problem that the route establishment method provided by the prior art cannot obtain the relevant information of the current area where the MSN is located in real time. Before the establishment is successful or the route has just been established, MSN has moved to a new area, so at this time the data transmission according to the established route cannot be routed to MSN
