Method for constructing network topology in wireless sense network

Abstract

A method for constructing network topology in wireless sense network includes the following steps: according to an amount of types of the sense terminal in the wireless sense network, configuring cluster heads with the same amount of types; assigning the cluster heads, according to a monitoring region scope, to different monitoring regions; periodically obtaining, by the cluster heads, sense information in the corresponding monitoring region, and determining whether a new sense terminal exists in the corresponding monitoring region; after determining joining a cluster managed by the cluster head, sending, by the new sense terminal, responsive information to the cluster head, requesting, by the cluster head, a central manage unit to adding the new sense terminal into the wireless sense network; adding, by the central manage unit, the new sense terminal to the wireless sense network; notifying, by the cluster head, that the new sense terminal has been added into the cluster, where the cluster head is, and added into the wireless sense network; and after obtaining the notification information, sending, by the new sense terminal, acknowledge information. The method of the present invention can dynamically manage the sense terminal, has a network topology structure with stable and high-efficient construction.

Description

technical field [0001] The invention relates to the communication technology of the Internet of Things, in particular to a network topology construction method of a wireless sensor network. Background technique [0002] The Internet of Things mainly solves the problem of connection between things and things, and between things and people. Compared with the interconnection between people on the Internet, the Internet of Things also incorporates items into the online world. Items are intelligent bodies that can perceive and be perceived. This makes the Internet of Things a network with a larger scale and more complex functions. Therefore, there must be various topology and coordination problems in the Internet of Things. [0003] When the Internet of Things incorporates objects into the network, it mainly relies on RFID technology, wireless sensor network (WSN) technology, intelligent embedded technology, etc. Their common feature is a large scale, but at the same time there a...

Problems solved by technology

[0005] The Internet of Things is committed to realizing the intelligence of things. Many of its applications are tasks with high data transmission rates, frequent communications, and even distributed computing, such as data collection, environmental monitoring, and target positioning. Due to the limitations of the Internet of Things itself , if a single node is allowed to complete data collection, transmission and calculation, its task will be very heavy
