Problems solved by technology
[0004]The conventional wireless sensor network is limited by the deployment scale, the transmission range of a single wireless sensor network is limited, and the transmission range cannot be adjusted flexibly. To expand the transmission range, additional sensor nodes need to be deployed. Different sensor networks in the same environment cannot transmit data to each other.

The present invention provides a system for combining wireless sensor networks. The system for combining wireless sensor networks includes a first sink transmitting a request to combine (RTC) and first routing-information. First nodes propagate data and instructions in a first wireless sensor network. The first nodes broadcast the RTC when the first nodes are boundary nodes. The first routing-information is established based on first transmission paths between the first sink and the first nodes. A second sink receives the RTC and the first routing-information from the first sink. The second sink transmits second routing-information to the first sink. The second routing-information is established based on second transmission paths between the second sink and the second nodes. The second node relays the RTC to the second sink according to a flag in a packet of the RTC. The first wireless sensor network combines with the second wireless sensor network to exchange the first routing-information and the second routing-information.
Description
technical field [0001] The present invention relates to a system and method for combining and establishing a secure channel of a distributed wireless sensor network, especially a distributed system that can expand the transmission range of a wireless sensor network by dynamically exchanging routing information. Background technique [0002] The invention relates to a distributed system for merging wireless sensing networks and establishing a safe channel. By establishing a safe channel for exchanging routing information of different wireless sensing networks, the effect of expanding the transmission range of the wireless sensing network is achieved. [0003] A general wireless sensor network (Wireless Sensor Network, WSN) is a network system composed of one to several data collection points and a large number of sensor nodes, and the components communicate with each other through wireless communication. The measurement network has the characteristics of low power consumption...
