Embodiment

[0045] like figure 1 As shown, the strip network of the present invention consists of a sink node ( figure 1 represented by a five-pointed star) and N wireless sensor nodes ( figure 1 Indicated by a small dot); the sink node is at one end of the strip network, and all wireless sensor nodes extend to the other end in a strip shape; each sensor node has the same computing and communication capabilities, and has the only network-wide The short address ID can dynamically adjust its own functions, and has the functions of sending, receiving and forwarding; the computing power of the sink node is not limited. The communication of all nodes is in the same channel, and the sink node sends data to the wireless sensor nodes in the form of broadcast, multicast or on-demand; the wireless sensor nodes send data to the sink node in the form of point-to-point.

[0046] like figure 2 As shown, the adaptive anti-interference wireless transmission method of the strip network specifically in...

Abstract

The invention discloses a self-adaptive anti-interference wireless transmission method for a band type network. The method includes the steps that when wireless sensor nodes have access to the network, short addresses are distributed by an aggregation node; the aggregation node broadcasts or request information to the wireless sensor nodes; the wireless sensor nodes judge whether they are within a routing radius range of a broadcasting issuing node; each wireless sensor node calculates a response slot time of its own and transmits a response in the response slot time; in the routing radius range, the nodes monitor a new routing node n to conduct broadcasting; the new routing node transmits data packet information to determine a latter route in the same broadcasting mode; the wireless sensor nodes judge whether they are destination addresses of a data packet link layer. The band type network can dynamically adjust the farthest transmission distance of the route according to the communication situation so as to adapt to external environmental inference; when the environmental interference is small, the information can be transmitted efficiently and quickly; when the environmental interference is large, the transmission distance is shortened.

Description

technical field [0001] The technical field of communication transmission of the present invention particularly relates to an adaptive anti-jamming wireless transmission method of a strip network. Background technique [0002] Strip wireless sensor network is a sensor network used in a specific environment, which can be applied to long-distance streets, real-time online monitoring of high-voltage transmission lines, online detection of oil and gas pipelines, online monitoring of cross-river bridges, expressways, mine environments, etc. . One of the typical applications is urban lighting system. [0003] Urban street lighting is an indispensable public facility in people's daily life. Street lighting consumes a lot of power, which brings a huge burden to the power grid. With the advancement of smart city construction, major cities across the country have successively launched smart street lighting systems to realize remote control of the entire street lighting system and ach...
